Endress+Hauser iTEMP TMT31 temperature transmitter

Temperature transmitters are an important link between temperature sensors in the field and higher levels of automation and analysis in the process industries.

The iTEMP TMT31 temperature transmitter for analog 4–20 mA signals improves on its RTD transmitter predecessors with better connection technology, available in two 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 a design that makes wire terminations in the connection head easier. Corrosion-free contacts are designed to ensure maximum reliability of measured value transmission for both connection variants.

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

In accordance with ATEX and CSA C/US standards, along with Pt100 and Pt1000 sensors, the TMT31 is approved for safe operation in Zone 2/Div. 2 hazardous areas (non-sparking). 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.
