E+H iTHERM CompactLine TM311 Thermometer

The Endress+Hauser iTHERM CompactLine TM311 stands as an exceptional hygienic temperature sensor tailored for the rigorous demands of modern processing plants. Operating in environments like food processing, beverage production, and biotechnology requires uncompromised cleanliness, fast thermal response, and long-term signal stability. The TM311 is built from the ground up to address these exact requirements, seamlessly handling routine Clean-in-Place (CIP) and Sterilization-in-Place (SIP) cycles without performance degradation.

Featuring a modular and space-saving architecture, this compact thermometer can be easily integrated into existing piping systems, tanks, or vessels. Its internal Pt100 RTD sensor element delivers high precision, rapid response times, and exceptional vibration resistance. High-grade surface finishes on all wetted parts minimize product adhesion and prevent bacterial growth, safeguarding product purity throughout every processing phase.

As a trusted distributor of process automation instrumentation, we provide genuine Endress+Hauser products with expert selection support. Whether your operation demands strict compliance with sanitary standards or continuous temperature tracking under challenging pressure and temperature conditions, the TM311 delivers dependable performance that keeps your process running smoothly.
