Hygienic and flexible: Temperature sensor with protection tube

The THTE temperature sensor is a hygienically-graded Pt100 resistance thermometer for applications in the food and beverage, pharmaceutical, cosmetics, and biotechnology industries. With the help of a thermowell that protrudes into the process, the sensor can be exchanged “dry“. That means that the vessel remains closed and potential hygienic risks are minimized. The thermowell is available in multiple insertion lengths and is installed at the vessel by common hygienically-graded process connections. High-grade stainless steel and a gap- and crevice-free design enable safe and clean processing. The THTE is well suited for CIP and SIP processes. This enables safe hygienic operation in conjunction with optimized equipment availability.

Besides its direct electrical connection to the Pt100 element, the THTE is available with an integrated transmitter with 4 mA ... 20 mA output signal.
