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.

By integrating a thermometer with iTHERM TwistWell thermowell with advanced helical design, operators can achieve superior steam quality and significantly reduce vortex-induced vibrations.
To meet the challenges of temperature monitoring in such critical processes, a thermowell design has been developed that responds to process changes up to five times faster than standard designs.
The Ziegler-Natta process uses hazardous chemicals like titanium tetrachloride. Precise temperature measurement is crucial to prevent runaway reactions and ensure safety and efficiency.
