Endress+Hauser TMT31 Temperature Transmitter RTD Input 36V, 85 °C, -40 °C

This temperature transmitter converts resistance temperature detector inputs into an analogue control signal for process monitoring. Designed for industrial environments, it provides a compact solution for interfacing RTD sensors with control systems while operating across a wide measurement range.

• Accepts RTD inputs and delivers analogue output 4-20 mA for control loops
• Measures process temperatures from -50 to 250 °C enabling broad thermal coverage
• Operates from a maximum 36V supply allowing flexible power arrangements
• Certified with a CE mark to meet relevant regional conformity requirements
• Functions in ambient conditions from -40 to 85 °C for varied site climates
• Constructed for use outside hazardous areas to suit standard industrial zones

• Suitable for temperature sensing in manufacturing process control panels
• Ideal for integration with PLCs and DCS using 4-20 mA inputs
• Used for monitoring heat treatment and thermal processing lines
• Can be used for HVAC plantroom temperature feedback loops
• Used with RTD probe assemblies in test and measurement rigs

It accepts RTD sensors, enabling connection to industry-standard resistance temperature detectors.

The transmitter can operate with ambient temperatures as low as -40 °C and as high as 85 °C.

It will handle process temperatures up to 250 °C and down to -50 °C.

No, it is not certified for hazardous areas and should be installed only in non-hazardous locations.
