Endress+Hauser TMT72 Temperature Transmitter Thermocouple, RTD Input 42V, 85 °C, -40 °C

This temperature transmitter converts sensor inputs into a proportional analogue signal for process monitoring and control. It accepts both thermocouples and resistance temperature detectors and is intended for industrial installations where compact sensing electronics interface with control systems. The unit is CE‑marked and designed to operate across typical ambient conditions encountered in plant environments.

• Accepts thermocouple and RTD inputs, enabling flexible sensor selection
• Outputs analogue signal suitable for 4-20 mA integration with control loops
• Operates from supply voltages up to 42 V, supporting varied power sources
• Measures process temperatures from -50 to 200 °C, covering wide process ranges
• Withstands ambient temperatures from -40 °C to 85 °C for harsh environments
• Compact DIN 44 mm housing for straightforward panel or head mounting

• Suitable for chemical reactor temperature feedback to PLCs
• Ideal for heat-exchanger outlet temperature monitoring in plant
• Used with thermocouples for high-temperature kiln measurement up to 200 °C
• Can be used for cold-room or freezer-line sensing down to -50 °C
• Used for retrofit into existing head-mounted instrumentation in control cabinets

It accepts both thermocouple probes and RTD elements, allowing connection to common industrial temperature sensors.

It provides an analogue output compatible with standard 4-20 mA loops for direct connection to PLCs, DCS or chart recorders.

The transmitter is specified for ambient operation between -40 °C and 85 °C, enabling use in both low-temperature and elevated ambient locations.

The maximum temperature input for the sensing element is 200 °C, with a minimum measurable process temperature of -50 °C.

The unit bears the CE mark, indicating conformity with applicable EU directives.
