TMS31 Product Overview
TMS31 is a high-performance temperature transmitter that supports resistance temperature detector (RTD) and thermocouple (TC) inputs, and outputs standard 4-20mA signals or HART communication. Its compact design is suitable for temperature measurement and remote transmission in industrial sites.
This transmitter features high accuracy, strong anti-interference capability, and wide temperature range operation, and is widely used in the petroleum, chemical, power, and metallurgical industries.
Main Technical Parameters
The following are the core technical specifications of the TMS31 for reference in engineering selection and procurement comparison.
| Parameter Item | Specification Description |
|---|---|
| Input Type | Pt100, Pt1000, Cu50, Cu100; K, E, J, T, S, B type thermocouples |
| Output Signal | 4-20mA (two-wire), optional HART protocol |
| Supply Voltage | 12-36V DC (standard 24V DC) |
| Accuracy Class | ±0.1% FS (RTD), ±0.2% FS (TC) |
| Ambient Temperature | -40℃ ~ +85℃ |
| Protection Rating | IP67 (enclosure) |
Wiring and Installation Steps
Correct wiring and installation are prerequisites for ensuring the measurement accuracy of the TMS31. Please operate according to the following steps:
- Confirm that the power supply is 24V DC and the polarity is correct.
- According to the sensor type, connect the RTD or TC signal wire to the corresponding terminal (refer to the terminal diagram in the manual).
- Connect a load resistor in series in the output loop (≤500Ω), and ensure that the loop current is within the 4-20mA range.
- Tighten the cable gland to ensure the protection rating reaches IP67.
- After power-on, observe whether the transmitter outputs normally, and perform zero and span calibration if necessary.
Configuration and Calibration Methods
Local Configuration
The input type, upper and lower range limits, and damping time can be set through the buttons or DIP switches on the transmitter. For specific operations, please refer to the configuration menu tree in the manual.
HART Configuration
If the HART function is optionally equipped, a handheld communicator or PC software can be used for remote configuration. It supports reading process variables, modifying the range, and diagnostic information.
Calibration Points
- Warm up for at least 15 minutes before calibration.
- Use a standard signal source to input the zero and full-scale signals.
- Adjust the output through the fine-tuning potentiometer or HART commands so that the error is within the accuracy range.
Common Troubleshooting
If abnormal output occurs during on-site use, refer to the following table to quickly locate the problem.
| Symptom | Possible Cause | Countermeasure |
|---|---|---|
| No output | Power supply polarity reversed or power failure | Check power supply polarity and measure terminal voltage |
| Output always 4mA | Sensor open circuit or incorrect input type | Check sensor wiring and reconfigure input type |
| Large output fluctuation | Interference or poor grounding | Use shielded wire with single-end grounding, keep away from power cables |
| Accuracy deviation | Not calibrated or sensor aging | Recalibrate, replace sensor if necessary |
Selection and Procurement Recommendations
When purchasing the TMS31, please specify the following information:
- Input type: RTD or TC, specific graduation number.
- Output signal: 4-20mA or HART.
- Installation method: integrated or split type, thread specification.
- Explosion-proof requirements: intrinsically safe or flameproof, corresponding certification required.
It is recommended to request the latest version of the TMS31 Chinese manual to confirm the wiring and configuration details of the specific model.
