iTEMP TMT128
DIN rail temperature transmitter

Transformation of the sensor signal into a stable and standardized output signal for all industries

The transmitter is designed for the transformation of a TC sensor signal in a fixed measuring range. The standardized output signal used for process measurement is a 4 to 20 mA signal. This means fast, easy and cost-saving temperature measuring as well as reliable and precise measured values for for a wide range of industry applications. Installation is realized on DIN rail according to IEC 60715 (housing width: 22.5 mm).
