Temperature sensors THTE

Category Tag
  • The sensor can be exchanged without opening the process, providing high equipment availability and minimizing hygienic risks
  • Safe hygienic operation: Wetted parts are made from high-grade stainless steel, hygienically-graded surface finish, and a gap- and crevice-free design
  • Rugged: Connection housing is easy to clean and splash water proof
  • Quick and safe installation
  • Very good long-term stability, accuracy and linearity
  • Quick response time
  • Optimal solutions for individual requirements due to versatile configurability


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.
