E+H iTEMP TMT31 RTD Temperature Transmitter

Compact Design & Flexible RTD Signal Conversion

The Endress+Hauser iTEMP TMT31 is a reliable, PC-programmable head transmitter tailored for converting resistance thermometer (RTD) signals into a standardized 4 to 20 mA analog output. Engineered for installation directly inside Form B connection heads, this compact unit bridges field-level temperature sensing with centralized control systems, ensuring clear and interference-free signal transmission over long distances.

Streamlined PC Configuration & Easy Maintenance

Designed with user efficiency in mind, the iTEMP TMT31 allows quick and hassle-free configuration via PC setup software (such as ReadWin 2000). Engineers can easily set customized measuring ranges, sensor types, fault monitoring thresholds, and units without needing complicated physical dip switches, significantly reducing commissioning time and maintenance overhead.

High Measurement Accuracy & Rugged Durability

Operating with high accuracy and low ambient temperature drift, the TMT31 guarantees stable process monitoring across wide operating temperatures. Its fully potted electronic housing protects sensitive circuits against ambient humidity, vibration, and mechanical stress, making it an ideal choice for continuous operation in demanding plant environments.
