The newly developed Endress+Hauser iTEMP TMT31 temperature transmitter for analog 4-20mA signals is characterized by its long-term stability, high accuracy and ease of use, making it an important pillar for reliable temperature measurement in process automation.

In order to keep the effort for commissioning, device configuration and maintenance as low as possible, the transmitter can either be ordered conveniently pre-configured or simply parameterized on site using free operating software such as FieldCare or DeviceCare from E+H with the aid of a laptop or tablet. 

Push-in terminals recommended

Using tool-free push-in-terminals will cut wiring time by up to 85% during temperature transmitter commissioning. For all those who prefer to use the proven screw terminal, there is also an optimized design for easier wiring available. Corrosion-free contacts ensure maximum reliability of measured value transmission for both connection variants.

High reliability in the process 

The iTEMP TMT31 temperature transmitter is approved for safe operation of sensor types Pt100 (IEC/GOST/JIS) and Pt1000 (IEC) in Zone 2 / Div. 2 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 accuracy of the temperature measurement of the entire system.
