WE-T100 uses a split design: the transmitter body is separate from the external pressure probe. The body supports rail, wall, pole and hoop mounting; the probe uses threaded mounting with M6*1, M8*1, M10*1, M12*1, M14*1.5, M16*1.5, M20*1.5, G1/8, G1/4, G1/2, ZG1/4, ZG1/2, PT1/4, PT1/2, NPT1/8, NPT1/4 or NPT1/2, other mountings on request. Match the fitting thread to the probe before installation. Power the P1 version from a wide voltage input of 9~30VDC, or use the P0 version with its 19000mAh lithium battery. The LoRa antenna fixes to the SMA female connector, maximum transmit power 22dBm. The specification prints no terminal-by-terminal wiring drawing, so confirm terminal assignment with the factory before energising.

WE-T100 measures gauge pressure. The conventional range is 0~1.6MPa and the ordered ranges are R10 0~1MPa, R16 0~1.6MPa, R25 0~2.5MPa and R40 0~4MPa, with other ranges customised. Accuracy codes are A01 0.1%, A25 0.25%, A05 0.5% and A10 1%, with minimum resolution 1kPa and stability 1%FS. Output follows the communication code: LR for LoRa on the 410.125~490.125MHz band, 4G for MQTT, HTTP and WES cloud service protocol, RS for RS485, NB for NB2. RS485 is compatible with WES-IO at a fixed 9600bps and with Modbus, with baud rates 2400, 4800, 9600, 19200, 34800, 57600 and 115200. Range and accuracy are fixed by the ordering code, for example WE-T100-LR-A10-R10-P0-M6; the specification prints no in-field range or offset register.

The WE-T100 product specification says nothing about field firmware updating and names no firmware version, update tool or configuration software. It states only the data path: the transmitter communicates with the WES Edge Computing Gateway over the WES-WIO wireless terminal communication protocol, reporting on-site pressure and condition detection data. Before any update is attempted, have the tool version and a parameter template ready, and record the ordering code, for example WE-T100-LR-A10-R10-P0-M6, the serial number and the communication settings, so parameters can be restored if something goes wrong. Ask ftd_sales@west-hn.com for the current firmware package, tool version and parameter backup procedure.

The WE-T100 specification has no step-by-step troubleshooting chapter. Its fault detection covers pressure threshold overrun, abnormal pressure value change and low battery, sent through the WES Device Management Platform for notification by SMS and email. Then confirm the installed range matches the process, one of R10 0~1MPa, R16 0~1.6MPa, R25 0~2.5MPa or R40 0~4MPa, and that the probe thread is correct and fully engaged. Check the supply, either the 9~30VDC input or the 19000mAh battery, and treat a low battery flag as a real cause. Judge the reading against the stated 0.5%FS accuracy, 1%FS stability and 1kPa minimum resolution. The document gives no zero or span adjustment, so escalate a persistent deviation to ftd_sales@west-hn.com.

State the base model WE-T100 and the full ordering code, since every option is fixed by the ordering code. Give the range you need: the conventional 0~1.6MPa, or R10 0~1MPa, R16 0~1.6MPa, R25 0~2.5MPa, R40 0~4MPa, or a customised range. Add the accuracy code, A01 0.1%, A25 0.25%, A05 0.5% or A10 1%. Add the communication method, LR for LoRa, 4G, RS for RS485 or NB for NB2, the power supply, P0 battery or P1 9~30VDC, and the probe thread, for instance M20*1.5 or G1/2. State how many units you need. A full example is WE-T100-LR-A10-R10-P0-M6. The specification shows no explosion-proof marking or other certification, so name any certification your site requires. Price, lead time and warranty terms are not stated there.

WE-T101 is a split level transmitter: the probe contacts the medium in a sealed measuring chamber and connects to the transmitter by cable. When installed, the metal probe should sink into the bottom of the container. Choose a place that is easy to maintain, away from vibration and heat sources. The process connection is M30x1.5 with D 30mm or M20x1.5 with D 20mm, and the fitting thread must match the product. Avoid collision or friction with the container wall. Lower the probe slowly into the medium to avoid impact on the diaphragm. The cable is a special waterproof cable, so avoid wear, puncture and scratch. Cable lengths are 5m, 10m, 20m, 50m or 100m. Housing is ABS/PC and the process connection 304SS or 316LSS.

WE-T101 measures liquid level as gauge pressure. The measurement range runs from 0m~1m to 10m, with accuracy 0.5%F.S and resolution 0.01m; ordered ranges are R05 0~5m and R10 0~10m. Output depends on the communication code: LR for LoRa on the 410.125~490.125MHz band, 4G, RS for RS485, NB for NB2. RS485 is compatible with WES-IO at a fixed 9600bps and with Modbus, default data format 115200, n, 8, 1. On site you can set Address (LoRa 1-99, RS485 1-64), Net 1-99, Channel 0-83 and Baudrate 4800, 9600, 19200, 38400, 57600 or 115200. Zeroing uses the Calibration item: keep the sensor in air, enter Setting, scroll to Calibration and confirm. A read example is 01 04 00 15 00 02 60 0F answered by 01 04 04 00 00 00 0A 7B 83, reading 0.1 m.

The WE-T101 instruction manual, version U-WE-T101-CN1 first edition August 2025, does not document a field firmware update and names no firmware file, update tool or configuration utility. It does provide Modbus register tables that include software version bytes and the hardware version, so the running versions can be read from the device. If an update is ever required, have the tool version and a parameter template ready, record the ordering code, for example WE-T101-LR-R10-P0, together with the current Address, Net, Channel and Baudrate values, and confirm the procedure with ftd_sales@west-hn.com before starting. The manual states nothing about what happens to saved parameters after an update.

The manual lists faults in this order. Meter not displayed: the battery is low, so replace the battery with a new one. Abnormal liquid level value: check for broken level probe cables. Unable to receive data: for 4G and NB install the SIM card correctly and check the local 4G signal strength; for LoRa check whether the supporting gateway is connected and whether the LoRa parameters agree with it. Card unreadable: reinsert the card, renew the card fee or unbind the card. Also confirm the probe reaches the right depth, judge the reading against the stated 0.5%F.S accuracy and 0.01m resolution, and check the supply is DC 9-30V or the 19000mAh battery. The manual prints no gain or span adjustment besides the zero Calibration item.

State WE-T101 with the full ordering code, since range, communication and power supply are fixed at order time. Give the range: R05 0~5m or R10 0~10m, within the 0m~1m to 10m measurement span. Give the communication method, LR for LoRa, 4G, RS for RS485 or NB for NB2. Give the power supply mode, P0 battery powered or P1 9~30V DC, and the cable length, 5m, 10m, 20m, 50m or 100m. State the process connection, M30x1.5 or M20x1.5, the wetted material, 304SS or 316LSS, and the cable sheath, PVC or PU. State how many units you need. A full example is WE-T101-LR-R10-P0. The manual shows no explosion-proof marking or other certification, so name any certification required. Price, lead time and warranty terms are not stated there.

WE-T103 uses a one-piece body with the probe on board, and the sensor measurement interface is an epitaxial gas duct whose length can be customised; the standard tracheal length is 1.5m. Mount the body on a 35mm rail: fit the accessories on the back of the transmitter, fix them with the two screws and snap the unit onto the rail. Wall, holding rod and hoop mounting are also supported. The measured medium must be compatible with the structural material and must not block the inlet hole; the medium is gas at -20~85 C. Keep the transmitter away from high voltage, serious electromagnetic interference and high-power equipment. Never pierce the pressure hole with iron wire or a steel needle, and do not press the diaphragm by hand.

WE-T103 measures differential pressure. The conventional range is +/-500Pa, and the ordered ranges are R1 +/-100Pa, R2 +/-500Pa, R3 +/-1000Pa and R4 +/-1500Pa. Accuracy is +/-2% FS, with accuracy codes A1 1% or A2 2%, minimum resolution 0.1Pa, stability better than +/-0.2% FS, and overload 150%F.S. Output follows the communication code: LR for LoRa on the 410.125~490.125MHz band, 4G, RS for RS485, NB for NB2. RS485 is compatible with WES-IO at a fixed 9600bps and with Modbus, default format 115200, n, 8, 1; the baud rate gear runs 0:4800 up to 5:115200, default 5. Read the pressure with 01 04 00 15 00 01 20 0E, answered 01 04 02 00 32 38 E5, which reads 50Pa. Zeroing uses the ZeroSet item with both sensor ends at the same pressure.

Firmware can be updated from the device cloud platform. In the mini program open the device, click O and M, then Firmware Upgrade and tap Upgrade; the device enters the upgrade state and you wait for the upgrade to end. The manual cautions that this is not necessary and to proceed with caution. The same O and M page offers Restart, Factory Reset, which restores device attribute values to factory defaults, and Recognize. Before updating, record the ordering code (for example WE-T103-LR-A1-R2-P0), Device ID, baud rate gear and thresholds, since the manual does not state which saved parameters survive. The manual is U-WE-T103-CN1, August 2025, and names no firmware version. Ask ftd_sales@west-hn.com for the current firmware package.

The manual lists faults in this order. Meter not displayed: the battery is low, so replace the battery with a new one. Pressure value is small: the pressure hole is blocked, so remove the gauge and clean the pressure hole. Unable to receive data: for 4G and NB install the SIM card correctly and check local 4G signal strength; for LoRa check whether the supporting gateway is connected and whether the LoRa parameters agree with it. Card unreadable: reinsert the card, renew the card fee or unbind the card. No data on the platform: check the procedure for bugs. Also confirm the two ducts are connected the right way round and are not kinked or blocked, and judge the reading against the +/-2% FS accuracy, 0.1Pa resolution and 150%F.S overload.

State WE-T103 and the complete ordering code, because communication, accuracy, range and power supply are fixed by selection. Give the range: R1 +/-100Pa, R2 +/-500Pa, R3 +/-1000Pa, R4 +/-1500Pa, or a customised range. Give the accuracy code, A1 1% or A2 2%. Give the communication mode, LR for LoRa, 4G, RS for RS485 or NB for NB2, and the power supply, P0 battery powered or P1 9~30V DC. Because the sensor interface is an epitaxial gas duct, state the tracheal length needed, as 1.5m is standard. State how many units you need. A full example is WE-T103-LR-A1-R2-P0. The document shows no explosion-proof marking or other certification, so name any certification required. Price, lead time and warranty terms are not stated there.

WE-T110 uses a split design, with the transmitter body separate from the external temperature probe. The probe mounting options run from M6*1, M8*1, M10*1, M12*1, M14*1.5, M16*1.5 and M20*1.5 through G1/8, G1/4, G1/2, ZG1/4, ZG1/2, PT1/4, PT1/2, NPT1/8, NPT1/4 and NPT1/2. The body supports rail, wall, pole and hoop mounting. Power the P1 version from a wide voltage input of 9~30VDC, or use the P0 version with its 19000mAh lithium battery. The LoRa antenna fits the SMA female connector, with maximum transmit power 22dBm. The body is IP67 rated and measures 78 x 121 x 51.4 mm, working from -20~70 C. The specification prints no terminal-by-terminal wiring drawing, so confirm terminal assignment with the factory before energising.

WE-T110 measures temperature. The conventional range is -50~200 C with other ranges customised, and the ordered ranges are R1 -50~200 C and R2 200~500 C. Accuracy is +/-0.3 C, minimum resolution 0.1, and stability better than 0.25%RH/Y. The accuracy level codes are A1 1/3B, A2 A, A3 B and A4 C. Output follows the communication code: LR for LoRa on the 410.125~490.125MHz band, 4G for MQTT, HTTP and WES cloud service protocol, RS for RS485, NB for NB2. RS485 is compatible with WES-IO at a fixed 9600bps and with Modbus, with baud rates 2400, 4800, 9600, 19200, 34800, 57600 and 115200. Range and accuracy are fixed by the ordering code, for example WE-T110-LR-A2-R1-P0-M20.

The WE-T110 product specification does not describe field firmware updating and names no firmware version, update tool or configuration software. It states only the reporting path: the transmitter reports to the WES Edge Computing Gateway through the WES-WIO wireless terminal communication protocol. Because the document is silent, nothing can be confirmed from it about what happens to saved parameters after an update. Before any update, have the tool version and a parameter template from the supplier ready, and record the ordering code, for example WE-T110-LR-A2-R1-P0-M20, the serial number and the communication settings, so parameters can be restored. Ask ftd_sales@west-hn.com for the current firmware package and procedure.

The WE-T110 specification has no troubleshooting chapter. The faults it does name are temperature threshold overrun, abnormal temperature change and low battery, reported through the WES Device Management Platform by SMS and email. Start from those: check whether a threshold alarm is active and whether the battery is low. Then judge the reading against the stated figures, accuracy +/-0.3 C, resolution 0.1, stability better than 0.25%RH/Y, and the -50~200 C or 200~500 C range. Check that the probe is fully inserted in the process and the thread properly engaged, and that the supply is 9~30VDC or the 19000mAh battery. The document gives no zero or offset adjustment, so escalate a persistent deviation to ftd_sales@west-hn.com.

State the base model WE-T110 and the full ordering code, because range, accuracy, communication, power and thread are fixed by selection. Give the temperature range: R1 -50~200 C, R2 200~500 C, or a customised range. Give the accuracy level, A1 1/3B, A2 A, A3 B or A4 C. Give the communication method, LR for LoRa, 4G, RS for RS485 or NB for NB2, and the power supply, P0 battery powered or P1 9~30VDC. Give the probe mounting thread, from M6*1 to M20*1.5 or the G, ZG, PT and NPT options, and state how many units you need. A full example is WE-T110-LR-A2-R1-P0-M20. The specification shows no explosion-proof marking or other certification, so name any certification required. Price, lead time and warranty terms are not stated there.

WE-T113 splits body and probe. Flange mounting is stated for the probe, the body takes rail or wall mounting, and the probe thread is customizable. Supply is P0 with a 19000 mAh battery or P1 with 9 to 30 VDC, IP67.

• Fit the body to a 35 mm rail with the supplied clip or to a wall bracket.
• Keep the probe sensing part below the body so condensation cannot reach it.
• In ducts, pass the probe through the flange interface, sensing face into the airflow and sealed; in rooms mount it 1.2 to 1.5 m high.

The document names only the SMA female antenna port and the RS485 or LoRa output and prints no terminal wiring table, so ask for the wiring and gland detail at ftd_sales@west-hn.com. No explosion-proof marking is given here.

WE-T113 measures -40 to 125 degrees C and 0 to 100 %RH, with accuracy +/-0.2 degrees C and +/-2 %RH, selectable +/-3 %RH or +/-5 %RH, and resolution 0.1 degrees C and 1 %RH. Sampling period default is 30 s, reporting cycle default 1 hour.

Output is LoRa on 410.125 to 490.125 MHz, 4G, NB or RS485. RS485 address is 1 to 64, LoRa address and net 1 to 99, channel 0 to 83. Baud rates are 4800, 9600, 19200, 38400, 57600 and 115200 bps, and the Modbus default format is 115200, n, 8, 1.

Holding register 0x0000 is the device ID, default 1, and 0x0014 sets the display unit, 0 Celsius or 1 Fahrenheit. To switch to Fahrenheit send 01 06 00 14 00 01 08 0E; the read request 01 04 00 16 00 01 D0 0E answers 01 04 02 00 41 79 00, read as 65 %RH.

The WE-T113 manual gives no firmware name or version. Its only update path is the O and M page of the WES Device Management Platform, which offers Firmware Upgrade, a step the manual marks as not necessary and to be done with caution.

• Before any update, read the software version from Modbus registers 0x0009 and 0x0010, and record your device address, LoRa net and channel, baud rate and thresholds.
• Factory Reset restores device attributes to defaults, and holding the key 10 to 11 seconds returns parameters to default.

The manual is U-WE-T113-CN1, first edition August 2025. Ask ftd_sales@west-hn.com for the firmware image and tool version.

Chapter 6 of the WE-T113 manual lists faults in this order. Meter not displayed is linked to a low battery, so replace it. Unable to receive data means checking the SIM card is fitted and checking local 4G signal strength. LoRa network not connected means checking that the supporting gateway is connected and that LoRa parameters match it.

A drifting or wrong reading is not in that table, so use the installation notes: keep the probe sensing part below the body so condensation cannot run down the leads, and avoid dead corners, heat and steam sources.

Check the supply, 9 to 30 VDC on P1 or battery on P0, then read the alarm code, where 6 is sensors. The document gives no zero or span procedure for this model.

Quote the WE-T113 by its ordering code: communication mode LR for LoRa, 4G, RS for RS485 or NB; accuracy level A1 for 1 %RH; range R1 for -40 to 125 degrees C; power P0 for battery or P1 for 24 VDC; and the probe thread specification, which is customizable.

• Also state the humidity range you need, 0 to 100 %RH, and the probe cable length, which the document does not list as a selection item.
• Give the reporting cycle you intend to use, since the document ties battery life to it, and the quantity of units required.

An example code from the document is WE-T113-LR-A1-R1-P0. Price, lead time and warranty terms are not stated in the document, so ask ftd_sales@west-hn.com for those.

WE-T122 splits body and probe, and the document gives straight pipe and drop-in probe paths, the drop-in version using a special waterproof air conduction cable. The body takes guide rail, wall, snap ring or hoop mounting.

• Supply is P0 with a 19000 mAh battery or P1 with 9 to 30 VDC, at IP67; mount the body on a guide rail, wall, snap ring or hoop.
• The drop-in probe is the wet part, so keep its cable and gland sealed.

The document prints no terminal wiring table and no thread for the drop-in probe; it names only the SMA female antenna port and the RS485 or LoRa output. Ask ftd_sales@west-hn.com for the wiring diagram and gland specification. No explosion-proof marking is stated.

WE-T122 measures conductivity over 0 ms/cm to 4 ms/cm, the conventional range, with other ranges customizable. Detection accuracy is 3 %FS and minimum resolution is 1 us/cm.

Output is LoRa on 410.125 to 490.125 MHz, 4G, NB or RS485, compatible with WES-IO at fixed 9600 bps and with Modbus. Baud rate options are 2400, 4800, 9600, 19200, 34800, 57600 and 115200, with data bits 7 or 8, stop bits 1, 1.5 or 2, and parity None, Odd or Even.

The ordering table uses R4 for the 4 ms/cm range and marks the accuracy rating as not applicable. The document prints no register map, no default baud rate, no default address and no command example, so ask ftd_sales@west-hn.com for the protocol list.

The WE-T122 product specification says nothing about firmware: no firmware version, no update procedure and no configuration tool name, so do not plan a field update from it.

What to have ready instead is the configuration data the specification does print, so you can ask for the right tool: the communication mode, the range code R4 for 4 ms/cm, the power code P0 for battery or P1 for 9 to 30 VDC, and the unit serial number.

It only states that the transmitter reports to the Shidian Technology equipment management platform and that it supports fault detection for a conductivity threshold exceeded, abnormal changes in conductivity value and low power. Send that list to ftd_sales@west-hn.com and ask for the current configuration tool.

The WE-T122 document has no troubleshooting chapter or fault table, so the checks below follow only what it states.

• Confirm the reading sits inside the 0 ms/cm to 4 ms/cm conventional range, since the specification gives 3 %FS accuracy and 1 us/cm resolution.
• Confirm the drop-in probe uses the special waterproof air conduction cable and that the probe and cable are intact at the intended immersion depth, because the document names that cable for this installation.
• Confirm the P0 battery or the P1 9 to 30 VDC supply is healthy, and that threshold or abnormal-change fault detection has not triggered.

The document gives no zero, span, grounding or shielding procedure; ask ftd_sales@west-hn.com for the calibration procedure.

State the WE-T122 base model plus the selection codes: communication mode LR, 4G, NB, RS or MB; the range code R4 for 0 ms/cm to 4 ms/cm; power mode P0 for battery or P1 for 9 to 30 VDC; and the sensor probe mounting, which the table marks not applicable.

• Add the conductivity range you actually need, since the document says other ranges can be customized, and the accuracy you need.
• State the probe cable length required, because the document does not list cable length as a selection item.
• State the quantity of units required.

An example code in the document is WE-T122-LR-R4-P0. Price, lead time and warranty conditions are not stated in this document, so ask ftd_sales@west-hn.com.

WE-T130 integrates body and probe in one unit and mounts by thread. The selection table lists M6*1, M8*1, M10*1, M12*1, M14*1.5, M16*1.5, M20*1.5, G1/8, G1/4, G1/2, ZG1/4, ZG1/2, PT1/4, PT1/2, NPT1/8, NPT1/4 and NPT1/2, with other methods customizable. Body mounting is by guide rail, wall, snap ring or hoop.

• Supply is P0 with a 19000 mAh battery or P1 with 9 to 30 VDC, at IP67.
• The unit is flameproof, explosion-proof mark Exib IIBT4, stated to comply with GB3836.1-2010 and GB3836.4-2010, so install within that marking.
• The document prints no terminal wiring table and names only the SMA female antenna port and the RS485 or LoRa output. Ask ftd_sales@west-hn.com for the wiring and gland detail.

WE-T130 measures gauge pressure over a conventional range of 0 to 1.6 MPa, with accuracy of +/-0.5 %FS and minimum resolution of 1 kPa. Range codes are R10 for 0 to 1 MPa, R16 for 0 to 1.6 MPa, R25 for 0 to 2.5 MPa and R40 for 0 to 4 MPa; accuracy classes are A01 for 0.1 %, A25 for 0.25 %, A05 for 0.5 % and A10 for 1 %.

Output is LoRa on 410.125 to 490.125 MHz at 22 dBm, or 4G, RS485 or Modbus. The protocol is WES-IO compatible at fixed 9600 bps and Modbus, with baud rates 2400, 4800, 9600, 19200, 34800, 57600 and 115200, data bits 7 or 8, stop bits 1, 1.5 or 2 and parity None, Odd or Even.

The document prints no register map, default address, default baud rate or command example, so request those from ftd_sales@west-hn.com.

The WE-T130 datasheet does not mention firmware at all: no firmware version, no update procedure and no configuration tool. It says nothing to confirm before an update and nothing about saved parameters, so do not plan a field update from it.

What to have ready instead is the ordering and configuration information the datasheet does print, so you can ask for the right tool and a parameter template: the communication mode, the range code such as R10 or R16, the accuracy class such as A01, the power code P0 or P1, the thread code such as M20*1.5, and the serial number of the unit.

Send that list to ftd_sales@west-hn.com and ask for the current configuration tool and its version.

The WE-T130 datasheet has no troubleshooting chapter, so the order below follows its own fault detection list.

• Pressure threshold overrun is first, so confirm the process pressure is inside the selected range, 0 to 1 MPa, 0 to 1.6 MPa, 0 to 2.5 MPa or 0 to 4 MPa, and that the alarm threshold is set correctly.
• Abnormal pressure value change is next, so compare the live reading against a known reference, keeping the stated accuracy of +/-0.5 %FS and 1 kPa resolution in mind.
• Low battery is the third condition, so check the P0 19000 mAh battery or the P1 9 to 30 VDC supply.

For zero, span, grounding or shielding checks the datasheet gives nothing; ask ftd_sales@west-hn.com for the calibration procedure.

State the WE-T130 base model and its selection codes: communication mode LR, 4G, RS or MB; accuracy class A01, A25, A05 or A10; pressure range R10 for 0 to 1 MPa, R16 for 0 to 1.6 MPa, R25 for 0 to 2.5 MPa or R40 for 0 to 4 MPa; power P0 for battery or P1 for 9 to 30 VDC; and the thread, for example M20*1.5, G1/4, NPT1/4 or PT1/4.

• State that you need the explosion-proof version, marking Exib IIBT4 to GB3836.1-2010 and GB3836.4-2010, and say where it will be installed.
• Give the quantity of units required.

An example code in the document is WE-T130-LR-A10-R10-P0-M6. Price, lead time and warranty conditions are not given in this document, so ask ftd_sales@west-hn.com.

WE-T131 is a split transmitter and probe. The probe installs by immersion using a specialized waterproof gas-conducting cable, and the probe is also listed as threaded; the transmitter body takes guide rail, wall, clamp or clamping ring mounting, at IP67.

• Supply is P0 with a 19000 mAh lithium battery or P1 with a 9 to 30 VDC wide input.
• The product is explosion-proof, intrinsically safe type, mark Exib IIBT4, stated as compliant with GB3836.1-2010 and GB3836.4-2010, so install within that marking.
• The document prints no terminal wiring table and names only the SMA male antenna connector and the RS485 or LoRa output. Ask ftd_sales@west-hn.com for the wiring and cable gland detail.

WE-T131 measures liquid level over 0 to 5 m, with detection accuracy of +/-0.5 %FS, minimum resolution of 0.1 m and stability of +/-0.3 %FS per year. The selection table offers range codes R05 for 5 m and R10 for 10 m, and accuracy class 0.5 %FS.

Output is LoRa on 410.125 to 490.125 MHz at 22 dBm with -147 dBm receiver sensitivity, 5 km in open line of sight, or 4G, RS485 or Modbus. The protocol is WES-IO compatible at fixed 9600 bps and Modbus, with baud rates 2400, 4800, 9600, 19200, 34800, 57600 and 115200, data bits 7 or 8, stop bits 1, 1.5 or 2 and parity None, Odd or Even.

The document prints no register map, default address or command example, so ask ftd_sales@west-hn.com for the register list.

The WE-T131 specification says nothing about firmware. It gives no firmware version, no update path and no configuration tool name, so there is no field update procedure to follow from this document, and nothing about what happens to saved parameters.

What to have ready instead is the configuration data the document does list, so you can request the correct tool: the communication mode, the range code R05 for 5 m or R10 for 10 m, the 0.5 %FS accuracy class, the power code P0 or P1, the probe installation method and the unit serial number.

Send that list to ftd_sales@west-hn.com and ask for the current configuration tool, its version and a parameter template.

The WE-T131 specification has no troubleshooting chapter, so this follows its own fault detection list.

• Liquid level threshold exceedance is first, so check whether the level is outside the configured threshold and whether the reading sits inside the 0 to 5 m range or the 10 m option.
• Abnormal liquid level fluctuation is next, so look for aeration or surface movement.
• Low battery is the third condition, so check the P0 19000 mAh lithium battery or the P1 9 to 30 VDC supply.
• Confirm the specialized waterproof gas-conducting cable is intact and its gland sealed.

The document gives no zero, span, grounding or shielding checks; ask ftd_sales@west-hn.com for the calibration procedure.

State the WE-T131 base model with its selection codes: communication mode LR, 4G, RS or MB; range R05 for 5 m or R10 for 10 m; accuracy class 0.5 %FS; power P0 for battery or P1 for 9 to 30 VDC; and the probe installation, threaded or immersion.

• State the level range you need in metres, since the document says other ranges can be customized, and the immersion depth or cable length required, which the document does not list.
• State that you need the explosion-proof unit with mark Exib IIBT4 to GB3836.1-2010 and GB3836.4-2010.
• Give the quantity of units required.

An example code in the document is WE-T131-LR-R10-P0. Price, lead time and warranty are not stated in the document, so ask ftd_sales@west-hn.com.

WE-T132 is a split transmitter. The host takes guide rail, wall, clamp or clamping ring mounting, and the external probe mounts direct or by thread. Probe thread options: M6x1, M8x1, M10x1, M12x1, M14x1.5, M16x1.5, M20x1.5, G1/8, G1/4, G1/2, ZG1/4, ZG1/2, PT1/4, PT1/2, NPT1/8, NPT1/4 and NPT1/2. Supply is the 19000 mAh lithium battery (P0) or 9 to 30 VDC (P1). LoRa and 4G units use an SMA female antenna socket; the RS485 unit is compatible with WES-IO at fixed 9600 bps and with Modbus. The sheet prints no RS485 terminal numbers, so ask ftd_sales@west-hn.com for the wiring drawing. Housing is IP67 and explosion-proof Exib IIB T4 under GB 3836.1-2010 and GB 3836.4-2010, so keep the intrinsically safe circuit and the certified entries intact.

The standard WE-T132 range is -50 to 200 deg C (R1); code R2 covers 200 to 500 deg C and other ranges can be customized. Output follows the communication code: LR LoRa on 410.125 to 490.125 MHz, 4G, or RS485. RS485 is compatible with WES-IO at fixed 9600 bps and with Modbus; baud rates 2400, 4800, 9600, 19200, 34800, 57600 and 115200 are supported, with 7 or 8 data bits, 1, 1.5 or 2 stop bits and none, odd or even checksum. The document prints no Modbus register map and no command examples. Setup is done on the 3-key interface with the 128x64 LCD or through the Shidian platform, and a customized range must be fixed at order. Accuracy class A1 to A4 (1/3B, A, B, C) is chosen in the model code.

The WE-T132 specification sheet names no firmware package, update tool or version and states no field update procedure, so it cannot say what happens to saved parameters during an update. What the sheet does describe is local configuration through the 3 keys, 2 LED indicators and the 128x64 LCD that shows sensor values and status, plus reporting to the Shidian Technology equipment management platform, where after-sales staff are notified by SMS or email. Before any update, write down the full model code such as WE-T132-LR-A2-R1-P0-M6, the accuracy class, the range, the supply mode and the current parameter values. Ask ftd_sales@west-hn.com for the tool version and the parameter template that match this unit.

The WE-T132 specification sheet has no troubleshooting section, so these checks follow its specifications:

• Confirm the probe is fully seated in the process thread and touches the medium.
• Check that the configured range matches the probe range in the model code.
• Check the battery, since low battery is a reported fault; on a P1 unit check 9 to 30 VDC.
• Check the SMA antenna is fitted and the LoRa or 4G link reaches the gateway.
• Confirm RS485 baud rate, data bits, stop bits and checksum match the master.
• Check grounding and shielding; the unit is rated 4 kV contact and 8 kV ESD.

Ask ftd_sales@west-hn.com for the full fault table.

State these points for a WE-T132 quotation: measurement range, standard -50 to 200 deg C or R2 200 to 500 deg C or a customized range; sensor probe installation thread and method, chosen from M6x1 through NPT1/2 or a custom method; communication mode LR, 4G, RS or MB (RS485/Modbus); accuracy class A1, A2, A3 or A4; power supply P0 battery or P1 9 to 30 VDC; antenna and any cable requirement; and the explosion-proof marking, Exib IIB T4 with GB 3836.1-2010 and GB 3836.4-2010. State the quantity and any accessory needed. Price, lead time and warranty terms are not given in this document and cannot be promised; send the request to ftd_sales@west-hn.com.

The WE-T160 host mounts on a guide rail, wall, snap ring or hoop. The ultrasonic probe is fixed by thread and is specified as Thread Fixed, NPT 2 in. Note the installation height, which is the distance from the probe to the bottom of the well, water or tank, and which must be set in the World Power Equipment Assistant applet before normal use. Inside the radiation radius of the probe there must be no obstacle higher than the object being measured; for the 8 m range that radiation radius is 1.5 m. Supply is the 19000 mAh lithium battery (P0) or 9 to 30 VDC (P1). The probe is IP68 and the host is IP67. This datasheet prints no output terminal numbers, no cable length and no gland detail, so ask ftd_sales@west-hn.com for the wiring diagram.

The WE-T160 measures level over 0 to 8 m, with a 0.3 m measuring blind spot, accuracy plus or minus 0.5 percent FS, minimum resolution 0.001 m and stability plus or minus 0.3 percent FS per year. The selection table lists R8 8 m only; other ranges can be customized. Communication codes are LR LoRa, 4G/cat1 and NB, and the selection table shows the accuracy rating and sensor probe mounting as N/A. Power codes are P0 battery and P1 9 to 30 VDC. Output is radio to the edge gateway, not a 4 to 20 mA loop; the datasheet gives no baud rate, no address and no Modbus register example. Configuration is by the host keys and LCD, and the level reference is set by entering the installation height in the World Power Equipment Assistant applet.

The WE-T160 datasheet names no firmware file, tool or version, and contains no update procedure, so it cannot say what happens to saved parameters during an update. What it does state is that the installation height is set with the World Power Equipment Assistant applet once installation is complete, and that over-limit level, abnormal level change and low power faults are sent to after-sales staff by SMS or email through the Shidian Technology equipment management platform. Before any update, record the full model code, for example WE-T160-LR-R8-P0, the P0 or P1 supply mode, the range, the installation height and the LoRa network settings. Ask ftd_sales@west-hn.com for the tool version and the parameter template that fit this unit.

The WE-T160 datasheet has no troubleshooting table, so these checks follow its installation notes:

• Clear the ultrasonic path: no obstacle higher than the measured object may sit inside the radiation radius, 1.5 m for the 8 m range.
• Confirm the reading is above the 0.3 m blind spot and that the probe is vertical over the liquid.
• Re-check the installation height in the World Power Equipment Assistant applet, because level is computed from it.
• Look for condensation, foam, vapour or turbulence on the path, and silt on the probe face.
• Confirm 9 to 30 VDC on P1 or replace the battery on P0, then check the probe cable, antenna and gateway link.

Ask ftd_sales@west-hn.com for the full fault list.

State these points for a WE-T160 quotation: level range, R8 8 m or a customized range; probe process connection, which the datasheet gives as Thread Fixed, NPT 2 in; communication mode LR, 4G/cat1 or NB; power supply P0 battery or P1 9 to 30 VDC; the required probe cable length; the medium and site conditions such as river, reservoir, tank, sewage cellar well or sewage well; the probe IP68 and host IP67 ratings; and the quantity, plus accessories such as the antenna or the mounting hoop, snap ring or guide rail hardware. Leave the accuracy rating and sensor mounting code to the supplier, as both are marked N/A. Price, lead time and warranty terms are not given in the document, so they cannot be promised.

The WE-T161 is a split radar level transmitter. Its process connection is thread M32x1.5 with D 10 mm, the cable is 1.5 m as standard and other lengths are customized, the housing is ABS/PC and the sheath is PVC or polyurethane PU. Mount the radar probe vertically over the medium, keep it at least 20 cm from the container side wall, and install it perpendicular to the liquid level so nothing interferes inside the 2.75 degree beam. Fit drip protection: bend the probe cable entry, cable and conduit downward; keep the unit away from vibration and heat sources. Power is the 19000 mAh lithium battery or 9 to 30 VDC, typical 24 V. Protection level is IP67. The manual prints no terminal numbers; ask ftd_sales@west-hn.com for the wiring sheet.

WE-T161 measures level from 0 m to 20 m, with a radar probe blind zone of 0.15 m or less, a beam angle of 2.75 degrees, accuracy plus or minus 2 mm and resolution 1 mm. Communication codes are LR LoRa, 4G/Cat1 and NB; LoRa runs in the 410.125 to 490.125 MHz band. The parameter list holds Address (1 to 99, LoRa only), Net (1 to 99, LoRa network ID) and Channel (0 to 83, LoRa channel), plus zero point calibration. Click the key to reach the QR code screen and triple click to enter parameter setting; single click moves the flag, double click edits and saves. Collection is 30 seconds and reporting 5 minutes by default, both adjustable, and both can be set from 1 minute to 18 hours. No Modbus register or command examples are printed.

WE-T161 firmware is updated from the World Electric Device Assistant mini program or web terminal, not from a file named in the manual. Connect the device by Bluetooth, then open the operation and maintenance page, where restart, identify and upgrade are listed; choose firmware upgrade, press upgrade and wait for the upgrade to finish. The manual gives no firmware version number and does not say what happens to saved parameters, so before you start record the device address, the LoRa Net and Channel values, the zero point calibration and the full model code such as WE-T161-LR-R20-P0, together with the manual version U-WES-T161-CN2, 2nd edition August 2025. Ask ftd_sales@west-hn.com for the tool version and parameter template.

Chapter 6 of the WE-T161 manual lists these faults in this order:

• Meter not displayed: the battery is low, replace it with a new one.
• Collection value abnormal: the probe connection is disconnected, so check that the field host is properly connected to the probe.
• Unable to receive data: on 4G or NB judge the state from the indicator light, install the SIM card correctly and contact the operator to set up the network or check local 4G signal strength; on LoRa check the gateway is connected and its parameters match the LoRa settings.
• Card unreadable: reinsert the card, check the card fee and the card binding.
• No data on the platform: there are bugs in the general procedures, check the procedure.

Give these details for a WE-T161 quotation: measurement range, R20 20 m; process connection, thread M32x1.5 with D 10 mm; communication mode LR LoRa, 4G/Cat1 or NB; power supply P0 battery powered or P1 9 to 30 VDC; cable length, standard 1.5 m or a customized length; and whether the cable entry needs drip protection or an extension. State the quantity and any accessory required, such as the antenna supplied in the standard configuration with the transmitter, instructions and certificate of conformity. Both the accuracy level and the sensor mounting rows of the selection table are marked N/A, so confirm those with the supplier. Price, lead time and warranty terms are not promised in this manual; send the request to ftd_sales@west-hn.com.

WE-T185 is a split transmitter. The host supports guide rail, wall, card ring and hoop mounting; the body clips onto a 35 mm guide rail fixed by two screws, or a fixing card held by a spring can be pushed in for screw or tie mounting. The process connections listed for the pressure side are M20x1.5 with D 20 mm, M27x2 with D 27 mm, M14x1.5 or NPT 1/2 with D 14 mm, G 1/2 with D 20.995 mm and G 1/4 with D 13.157 mm. Supply is the 19000 mAh lithium battery or DC 9 to 30 V. The cable is 1.5 m; other lengths are customized. Housing is ABS/PC, the pressure process connection is 304SS or 316LSS and the methane connection is aluminium alloy. Protection is IP67. The manual prints no terminal numbers or gland detail, so ask ftd_sales@west-hn.com.

WE-T185 measures gauge pressure from -0.1 MPa to 100 MPa and methane gas from 500 to 10000 ppm, with accuracy plus or minus 0.5 percent FS, minimum resolution 1 kPa, media temperature -20 to 85 deg C and overload pressure 150 percent FS. Sampling can be set from 1 s to 65535 s, default 30 s; reporting from 10 s to 65535 s, default 1 hour. Output is LoRa, 4G/Cat1, RS485 or NB radio rather than a 4 to 20 mA loop, and the manual gives no baud rate, address or Modbus register example. Zero calibration is local: hold the channel pressure environment at 0 Pa, enter the Setting page, move the list to Calibration1 or Calibration2, double click and wait for the calibration success prompt. Accuracy codes are A01 to A10 and range codes R10 to R40.

The WE-T185 manual describes firmware upgrade as an action on the operation and maintenance page of the Shidian device assistant mini program: open O and M, press firmware upgrade, press upgrade, and the device enters the upgrade state, so wait for it to end. The manual notes that an upgrade is not required unless necessary and asks you to operate with care. It names no firmware version or separate configuration tool and does not state what happens to saved parameters. Before upgrading, record the Calibration1 and Calibration2 zero values, the sampling and reporting periods and the model code, and keep manual version U-WE-T185-CN1, first edition Aug 2025. Ask ftd_sales@west-hn.com for the tool version and parameter template.

Chapter 6 of the WE-T185 manual lists these faults in this order:

• No display on the meter: the battery is low, replace it with a new one.
• Pressure value too small: the inlet hole is blocked, take the instrument down and clean it.
• Cannot receive data, 4G or NB: judge the state from the indicator light and, if it has not registered, check the SIM card fitting and the wireless service area.
• Cannot receive data, LoRa: check whether the matching gateway is connected and whether the LoRa and gateway parameters are consistent.
• Card unreadable: reseat the card, check the fee and unbind it.
• No platform data: a program bug, check the procedure.

Also keep the inlet hole clear of the medium and the gas guide tube open to atmosphere.

State these items for a WE-T185 quotation: measurement range, gauge pressure from -0.1 MPa to 100 MPa with codes R10 0 to 1 MPa, R16 0 to 1.6 MPa, R25 0 to 2.5 MPa and R40 0 to 4 MPa, or a customized range, plus methane detection from 500 to 10000 ppm; accuracy class A01 0.1 percent, A25 0.25 percent, A05 0.5 percent or A10 1 percent; probe thread from M6x1 through NPT1/2 or a custom size; communication LR LoRa, 4G/Cat1, RS RS485 or NB NB2; power P0 battery or P1 9 to 30 V DC; cable length 1.5 m or customized; and process connection material, 304SS or 316LSS for pressure and aluminium alloy for methane. State the quantity and accessories. Price, lead time and warranty cannot be promised.

Mount the WE-T214 host where it is easy to operate and maintain. Use the two black screws to fix the clamp on the back of the main unit, then the four expansion screws for the wall mounted card, or use the guide rails, hoops and snap rings listed for the host. Bury the 3-in-1 probe horizontally at the depth you want to monitor, clear weeds, gravel and straw first, keep the probe tight against the hole wall, and backfill with the original soil. Power comes from 9~30DC, typically 24V, from the 19000mAh lithium battery or the 40W20AH solar panel. The host is IP67 and the probe is IP68. The probe cable and the power cord each use a 0.5m plus 0.5m waterproof screw cap connector. Fit the supplied antenna and follow the Chapter 7 wiring diagram.

Configure the WE-T214 over Bluetooth with the desktop tool SerialTest. AT+PERIOD sets the reporting cycle and sampling period, for example AT+PERIOD=300,120. AT+LOCATE sets the positioning period and timeout, for example AT+LOCATE=600,60. AT+APN sets the access point name, user name, password and authentication method; the example uses apn cmnet with empty user and password and authentication 0, where 0 is none, 1 PAP, 2 CHAP and 3 PAP or CHAP. Reporting and sampling can be set from 1min to 18 hours. The device measures soil temperature, moisture and conductivity and reports JSON id, IMEI, time, humidity, temperature, EC, longitude and latitude to the Shidian platform or a third party platform over MQTT, HTTP or WES cloud service protocol.

The WE-T214 manual has no firmware update section and does not name a firmware file or a version, so nothing in this document describes how a field update is done, what to confirm first, or what happens to saved parameters and the SIM or network profile. What the manual does document for local work is the desktop Bluetooth configuration tool SerialTest with the AT commands PERIOD, LOCATE and APN, plus the LCD and the side buttons for on-site checks. Have the device serial number, the current version shown on the unit and your APN details ready when you ask, and send the request to the support team at ftd_sales@west-hn.com.

Use the Chapter 8 troubleshooting order for the WE-T214. If the meter is not displayed, first detect the power interface because the unit may not be connected to power, then charge the solar battery because the solar cells may have run out. If the collection value is abnormal, check that the field host is properly connected to the probe, then detect the device APN, since APN misconfiguration also corrupts reporting. If data cannot be received, install the SIM card correctly and confirm you are in the service area, otherwise contact your network operator or check local 4G signal strength. If the card is unreadable, reinsert it, check card fee renewal, or unbind the card.

To request a quotation for the WE-T214, state the model and confirm the 3-in-1 soil probe configuration for soil temperature, moisture and conductivity. Say which radio you need: LoRa in the 410.125~490.125MHz band, or 4G using MQTT, HTTP and WES cloud service protocols for the region EMEA, Australia and New Zealand with LTE FDD bands B1/3/5/7/20/28. State the power supply, either 9~30DC typical 24V, the 19000mAh lithium battery or the 40W20AH solar panel. Confirm the antenna, the cable length, and any accessories such as the back-mounted card holder, screw mounting pallet and screw package. Give the number of units; the standard shipping carton holds 10.

Clip the WE-T233 main unit onto a 35mm rail, fixing the back accessories with two screws, or fit the fixing clip so it can be held with screws or cable ties. Keep the probe away from organic solvents, coatings, chemicals, oils and high concentration gases, do not block or contaminate the air intake, and never seal the electrochemical sensor in resin or an oxygen-free space. Wire by cable colour: red is DC12~24V positive, black is DC12~24V negative, yellow is 485A and green is 485B. Supply is 9~30DC, typical 24V, or the 19000mAh lithium battery. Screw the SMA female antenna onto the radio connector and tighten it. The main unit is IP67, the probe housing is aluminum alloy and the cable is 1.5m unless customized.

Set the WE-T233 either from the panel or over Modbus. The panel offers Address, LoRa Net, LoRa Channel and Baudrate: Address is 1-64 for LoRa and 1-99 for RS485, Net is 1-99, Channel is 0-83, and the RS485 rates are 4800, 9600, 19200, 38400, 57600 and 115200, with Modbus defaulting to 115200, n, 8, 1. Holding register 0x0000 is the device ID, default 1, and 0x0001 selects the baud rate from 0 for 4800bps up to 5 for 115200bps. A measurement request frame is 01 04 00 16 00 02 90 0F and a typical response 01 04 04 42 05 51 EC C3 E0 reads 33.33 ppm. The device reports to the Shidian platform through the Shidian Equipment Assistant mini program or the web address.

The WE-T233 manual does not give a firmware name, a version number or a step by step field update procedure. The nearest statement is that after Bluetooth connecting the device in the Shidian Equipment Assistant mini program you can restart, identify and upgrade it from the operation and maintenance section. Nothing is said there about what to confirm before an upgrade or about the effect on saved parameters and the SIM or network profile. Have the device serial number, the current version, your network and LoRa parameters and your APN details ready, and address the request to the support team at ftd_sales@west-hn.com.

Follow the WE-T233 fault table in its own order. If the instrument panel shows no display, the cause is low battery capacity, so replace the battery. If collected values are abnormal, the probe connection may be disconnected, so check that the on-site host and probe are properly connected. If data cannot be received, check the 4G or NB status through the indicator lights, then confirm the SIM card is correctly installed and within a wireless service area; if the LoRa network was not connected, check that the supporting gateway is connected and that the LoRa parameters match the gateway. If the card cannot be read, reinsert it, check card bill renewal, or unbind the card. If the platform has no data, check the procedure.

To quote a WE-T233, state the communication method code: LR for LoRa, RS for RS485, 4G for 4G/Cat1 or NB for NB. Confirm the power supply code, P0 for battery-powered or P1 for 9~30VDC, giving a model such as WE-T233-LR-P0. Note the measurement you need, ammonia NH3 over 0~99.99ppm with 0.01ppm resolution, and the SMA female antenna interface. Ask for the 1.5m cable or specify another length, because other lengths require customization. List the accessories you need from the standard pack, which has one ammonia transmitter, one manual, one antenna and one certificate of conformity. State the quantity of units and where the device will be installed.

Fix the WE-T800 by installing the bracket on the wall, then position the device according to the direction on the bracket and secure it with screws on both sides. Wire the A interface as 1 import DC+, 2 import DC- and 3 input location; the B interface as 1 output POW, 2 output GND, 3 RS485A and 4 RS485B; the C interface as AI 1+, AI 1-, AI 2+, AI 2-, DI 1+, DI 1-, DI 2+ and DI 2-. Power from 9~30VDC, typically 24V, or the 114000mAh or 228000mAh lithium battery. Mount the antenna in a signal-optimized area, because a poor spot increases communication power consumption and reduces battery life. Keep the external quick-connect plug properly connected to prevent water ingress. The device is IP68 and the shell is ABS/PC.

The WE-T800 provides 1 RS485 channel, 2 AI channels and 2 DI channels. RS485 runs 4800-115200bps with MODBUS-RTU, AI accepts 4~20mA, DI handles switching quantity and pulse counting, and the output power supply is DC3.6V/5V/12V adjustable. Over 4G it uses MQTT, HTTP and WES cloud service protocols on LTE FDD B1/3/5/8 and LTE TDD B34/38/39/40/41, and the sampling period and reporting cycle are each settable from 10s to 18h. Configure northbound parameters such as Report Period, Cloud IP, Cloud Port, Username, Password, Topic and Enable, and southbound AI period, DI period, RS485 period and RS485 baudrate. The device reports to the Shidian platform through the Shidian Equipment Assistant mini program or the web address.

The WE-T800 manual shows the firmware version in the System page, which displays the device version number, SN, BLE MAC, IMEI and language, and the Shidian Equipment Assistant mini program offers a restart, identify and upgrade action under Operations after a Bluetooth connection. Beyond that the document names no firmware file, no version string, no step by step update method and no statement about what to confirm first or how saved parameters and the SIM or network profile are affected. Have the serial number, the version currently shown, the channel and platform settings and your APN details ready, and ask the support team at ftd_sales@west-hn.com.

Work through the WE-T800 fault table in its own order. If the instrument display is absent, the battery level is low, so replace it. If an acquisition value is abnormal, the sensor connection may be disconnected, so if the channel status is disconnected check that the on-site host is connected to the probe; if the RS485 channel configuration does not match the actual sensor register, reconfigure those parameters. If data cannot be received, 4G network registration may have failed, so install the SIM card correctly, contact your network provider to set up the network, check local 4G signal strength and replug. If the card is not read, replug, check data plan renewal or unlink the card. If the platform has no data, audit the program.

To request a WE-T800 quotation, state the power supply code: P0 for the 114000mAh battery, P1 for 9~30VDC or P2 for the 228000mAh battery, and the collection code: G0 for RS485 data acquisition or G1 for RS485 data acquisition plus 2-channel AI, as in WE-T800-P0-G0. Confirm the 4G service with LTE FDD B1/3/5/8 and LTE TDD B34/38/39/40/41 and the SMA female antenna, and the MQTT, HTTP and WES cloud service protocols. Mention the RS485 baud rate and the AI or DI channels you will use. State the cable and accessory needs and the quantity of units. Customization requires a consultation with customer service.

Mount the WE-X240 on a rail, since the datasheet specifies rail mounting and a gateway-powered supply rather than a separate power input. Wire either a three-wire probe, with line A to CH- and the B line to the two CH+ terminals because B is not distinguished, or a two-wire probe, with line A to CH- and line B to CH+, keeping the two CH+ shorted externally. The module offers 4 channels over a 2-wire or 3-wire connection. Its working range is -20 to 70 degrees C at 5% to 95% relative humidity non-condensing, storage is -30 to 80 degrees C, protection is IP20 with 4KV contact and 8KV non-contact ESD, the housing is ABS/PC and the size is 25 by 110 by 117 mm.

The WE-X240 is a four-channel temperature module. Each channel resolves 0.1 degrees C over a temperature measurement range of -200 to 850 degrees C, with precision stated as plus or minus 0.5% FSR at 25 degrees C, and high accuracy reaching 0.5%. A 0.96 inch 80 by 160 dot matrix colour LCD shows device information and status, and one page turn button and two status LEDs are provided. When you change the RTD type it must be set on the web side; if the web-side setting differs from the external connection type it causes inaccurate temperature measurement and even device damage. The datasheet stays on the hardware side: it documents the wiring, the RTD type and the physical data only, and states no communication protocol, no baud rate, no device address and no reporting platform, so ask the supplier for those details.

The WE-X240 datasheet says nothing about firmware, so there is no firmware or configuration tool name, no version, no update method and no note on saved parameters. Do not assume an update path from the datasheet alone. What you can confirm from it is the hardware side: 4 channels, 0.1 degrees C resolution, precision plus or minus 0.5% FSR at 25 degrees C over -200 to 850 degrees C, 2-wire or 3-wire wiring, and the rule that the RTD type must be set on the web side and must match the external connection. For any firmware question, have the device serial number and current version ready and ask the support team at ftd_sales@west-hn.com.

The WE-X240 datasheet has no troubleshooting section, so these are the checks it does support. If a temperature reads wrong, first confirm the wiring matches the probe: three-wire uses line A to CH- and the B line to the two CH+ terminals, two-wire uses line A to CH- and line B to CH+ with the two CH+ shorted externally, and an open or wrong pairing will misread. Then confirm the RTD type set on the web side matches the type actually connected, since the datasheet warns that a mismatch gives inaccurate measurement and can damage the device. Confirm the module is properly seated on the rail and is powered through the gateway. For further diagnosis ask the support team at ftd_sales@west-hn.com.

The WE-X240 datasheet contains no selection or ordering code table, so a quotation request must be built from its stated data. State the model WE-X240 and confirm the four channel temperature acquisition configuration. Say whether each input is 2-wire or 3-wire, and name the RTD type, because the type must be set on the web side and must match the connection. Confirm the range you need within -200 to 850 degrees C and the 0.1 degrees C resolution. Note the rail mounting, the IP20 rating and the gateway-powered supply. State the quantity of units and any integration requirement, for example combining the module with Shidian T280, and ask the support team for anything not shown.

Snap the WE-X280 onto a 35mm rail in the direction shown, choosing a place that is easy to operate and maintain and away from vibration and heat sources. Power it with 24VDC. The gateway carries two RS485 serial ports on industrial-grade terminal interfaces, one RJ45 Ethernet port at 10M/100M adaptive, an I/O module expansion interface for up to 16 modules, an external SIM card slot, an external TF card slot and external antenna sockets. Screw the SMA male 4G antenna and LoRa antenna onto the ANT connectors and tighten them to protect signal quality. The unit is IP20 with 4KV contact and 8KV non-contact ESD, the housing is ABS/PC and the size is 38 by 110 by 117 mm at 205g. Check packaging and connections before power-on.

The WE-X280 converges LoRa wireless and RS485 wired devices and uplinks by 4G full Netcom or Ethernet. One machine connects 128 wired or wireless transmission and sensing devices and can be expanded to 16 IO node devices, reporting with MQTT plus custom JSON. 4G uses LTE FDD B1/3/5/8 and TDD B34/38/39/40/41; LoRa covers 410.125~490.125MHz. Local configuration is over BLE. Holding register 0x01 holds the local IP, default 192.168.1.100, 0x03 the gateway IP 192.168.1.1, 0x05 the subnet mask 255.255.255.0, 0x08 the cloud IP 192.168.30.171 and 0x0A the cloud port 5088. Input registers start at 0x0000 for PID and 0x0007 for firmware version. The gateway is added as a Basic Master Module on the platform.

The WE-X280 supports an over the air upgrade and shows it on the indicators: the OTA state is green with a 0.25s period flash and a factory reset is 0.1s. In the World Electric Device Assistant mini program the O and M menu can restart, restore, identify and upgrade the device, and Modbus input registers 0x0007 and 0x0008 carry the firmware version bytes while 0x0009 carries the hardware version. The manual gives no firmware file name, no version string and no statement about what to confirm before an upgrade or how saved parameters and the SIM or network profile behave. Have the serial number, the version read from the registers and your network details ready, then ask ftd_sales@west-hn.com.

Follow the WE-X280 fault table in its own order. If the indicator light does not come on at all, the power supply is not connected, so replug it. If the SIM card is not readable, the card may not be inserted, not charged or bound, so reinsert it, check card fee renewal or unbind the card. If there is no data on the platform, the cause is bugs in general procedures, so check the procedure. If the system lights up but the cloud does not, the local signal is too weak or the network is misconfigured, so check the network. Also confirm that the LoRa over the air baud rate, LoRa network ID and LoRa network channel of each sub-device match.

To quote a WE-X280, state the model and that you need the industrial edge computing gateway with 4G full Netcom, Ethernet, LoRa and RS485. Confirm the 4G bands LTE FDD B1/3/5/8 and TDD B34/38/39/40/41 and the 410.125~490.125MHz LoRa range with its antennas. State the 24VDC power supply and note that the SIM card slot, TF card slot and antenna sockets are external. Say how many devices the site will connect, up to 128, and how many IO modules, up to 16. Ask for the standard package: one gateway, one 24V DC power supply, one 4G antenna, one LoRa antenna, one Ethernet cable, instructions and a certificate of conformity, and give the quantity of units.
