Temperature Transmitter

The Endress+Hauser iTEMP TMT31 temperature transmitter for analog 4-20mA signals offers connection technology, available in two optimized formats. The first incorporates push-in terminals, enabling tool-free, secure field wiring in a matter of seconds. It is also available in the classic screw terminal format, with an optimized design that makes wire terminations in the connection head easier. Corrosion-free contacts ensure reliability of measured value transmission for both connection variants.

The TMT31 is approved for safe operation in Zone 2/Div. 2 hazardous areas (non-sparking) in accordance with ATEX and CSA C/US standards, along with Pt100 and Pt1000 sensors. Additionally, the sensor adjustment parameter in the head transmitter can be modified according to Callendar-Van Dusen equations (CvD) to match the connected RTD sensor characteristics, further refining the temperature measurement accuracy of the entire system.

For fast commissioning, users have the option to receive the TMT31 transmitter pre-configured from the factory, or to apply custom parameterization on-site with free configuration software, such as Endress+Hauser FieldCare or DeviceCare. These software packages run on a variety of operating systems, both on laptops and tablets. The USB configuration kits required for this, such as TXU10 or Commubox FXA291, are also available from Endress+Hauser as accessories.
