Endress+Hauser’s iTEMP TMT31 RTD temperature transmitter for analog 4-20mA signals offers easy installation and commissioning. It can be ordered with screw or push-in terminals, and can be delivered pre-configured or parameterized on site from a laptop or tablet

The new iTEMP TMT31 temperature transmitter for analog 4-20mA signals is designed by Endress+Hauser to deliver great long-term stability, high accuracy and ease of use.

In order to minimize the effort involved in commissioning, device configuration and maintenance, this RTD head transmitter for Pt100/Pt1000 sensors can be ordered pre-configured or parameterized on site from a laptop or tablet using free operating software DeviceCare from Endress+Hauser. The USB configuration kits required for this, such as TXU10 or Commubox FXA291, are also available as accessories.

The iTEMP TMT31 also boasts further improvements in connection technology. It is available in two optimized versions. One comes with push-in terminal for tool-free, secure wiring in just a few seconds. The other, the classic screw terminal option, has been optimized to make wiring the connection easier than ever. With both variants, corrosion-free contacts ensure maximum reliability of measured value transmission.

The iTEMP TMT31 is approved for safe operation of sensor types Pt100 (IEC/GOST/JIS) and Pt1000 (IEC) in Class I, Division 2, Groups A, B, C, D hazardous areas (non-sparking). Optionally, the sensor characteristics of the connected RTD can be adjusted to the head transmitter by means of a transmitter-sensor adjustment using the Callendar-Van Dusen equations (CvD), thus further increasing the temperature measurement accuracy of the entire system.
