The transmitter is designed for the transformation of a thermocouple (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.

Since the temperature of compressed hydrogen increases with expansion during filling, temperature measurement is essential at hydrogen filling stations for safety reasons.
Our non-invasive thermometer can be easily retrofitted to the existing pipe and integrated into the control system to enable efficient stand-by operation of a turboset.
The Ziegler-Natta process uses hazardous chemicals like titanium tetrachloride. Precise temperature measurement is crucial to prevent runaway reactions and ensure safety and efficiency.
