iTemp TMT31 temperature transmitter for analog 4-20mA signals improves on its RTD predecessors with better connections, and is available in two optimized formats. The first incorporates push-in terminals, enabling tool-free, secure field wiring in seconds. It’s also available in the classic screw-terminal format, with an optimized design that makes terminations in the connection head easier. Corrosion-free contacts ensure reliability of measured value transmission for both formats.
For fast commissioning, users can get TMT31 preconfigured, or apply custom parameterization onsite with free configuration software, such as Endress+Hauser’s FieldCare or DeviceCare, which run conveniently on many operating systems on laptops and tablets. The required USB configuration kits, such as TXU10 or Commubox FXA291, are available as accessories.
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. Also, the sensor adjustment parameter in the head transmitter can be modified according to Callendar-Van Dusen equations (CvD) to match connected RTD sensor characteristics, further refining the temperature measurement accuracy of the entire system.
