TMT80-AA | TMT80-1014/0 Temperature Transmitter Overview
TMT80-AA and TMT80-1014/0 are widely used 4-20mA output temperature transmitters under E+H, capable of connecting to both RTD and thermocouple sensors.
This model is factory-configured by default as 3-wire, 0-100℃, and supports online parameter modification, meaning a single model can be adjusted to any range and wiring method required on site.
Outer Ring Dimensions and Installation Matching
Outer ring dimensions usually refer to the housing or mounting bracket dimensions of the transmitter. Different TMT80-AA models differ in outer ring dimensions to suit different installation environments.
- Before selection, confirm that the outer ring dimensions match the on-site installation space;
- Ensure stability and safety after installation, avoiding loosening caused by vibration;
- Reserve space for wiring and commissioning to facilitate subsequent maintenance.
Correct Use and Wiring Key Points
Pre-installation Inspection
- Confirm that the measured medium temperature is within the transmitter's measuring range;
- Verify the sensor type (RTD or thermocouple) and wiring method;
- Complete wiring strictly in accordance with the manual requirements.
In-operation Inspection
- Regularly check whether the power supply voltage is stable;
- Confirm that the output signal is normal, without drift or disconnection;
- Troubleshoot abnormalities promptly to ensure measurement accuracy and stability.
Parameter Configuration Method
The TMT80-AA supports multiple configuration combinations and can be flexibly set according to actual working conditions. Common optional configurations include RTD input, thermocouple input, and analog output, etc.
- Clarify the measured medium, temperature range, and measurement accuracy requirements;
- Select the matching input type and output method;
- Confirm compatibility with the control system or other equipment;
- Modify parameters online and save them, recording configuration information if necessary.
Replacement and Selection Guide
Replacement Precautions
- Prefer a transmitter of the same model and specifications to ensure accuracy and stability;
