Installation and Commissioning Points
Installation Steps
- Confirm that the transmitter range matches the sensor type.
- Install the transmitter in the temperature sensor junction box or on a nearby bracket.
- Connect the power supply, sensor, and output loop according to the wiring diagram, paying attention to polarity.
- After power-on, use a HART communicator or configuration software to calibrate zero and span.
- Check whether the output current corresponds to the set temperature to complete commissioning.
Precautions
- Avoid installation near strong electromagnetic interference sources.
- Ensure the ambient temperature is within the allowable range; add thermal insulation measures if necessary.
- Terminals must be tightened to prevent signal fluctuations caused by loose connections.
- Regular calibration is recommended for long-term use, usually every 12 months.
Selection and Procurement Recommendations
When purchasing the TMT86, it is necessary to specify the input type, range, output mode, and process connection size. If HART communication is required, please confirm that the transmitter firmware version supports it. It is recommended to purchase from authorized distributors and request the Chinese manual and calibration certificate.
Correct selection ensures long-term stable operation of the temperature transmitter under harsh working conditions and reduces maintenance costs.
