The TM4941 is a long-probe hygienic temperature sensor designed for deeper process temperature measurement. It uses a Pt100 Class A element and provides a 150 mm installation length. The Clamp DN50 process connection is suitable for larger hygienic process systems. Electropolished 316L stainless-steel construction provides durability and cleanability. The sensor is designed for continuous temperature monitoring in food, beverage and industrial process applications.
Explore performance details, construction highlights, applications, and technical information in one clear overview.
The TM4941 is designed for tanks and vessels requiring extended probe insertion. Its 150 mm installation length enables deeper measurement inside process media. The Pt100 element provides standardized and repeatable temperature sensing. The DN50 clamp interface supports hygienic installation. The sensor is suitable for liquid and gaseous process media.
The measuring range extends from -40 to 150 °C. The Pt100 Class A element supports accurate temperature monitoring. The long 150 mm probe enables measurement deeper inside larger process vessels. Fast dynamic response supports monitoring of changing process temperatures. The sensor can be connected to suitable evaluation units.
The Clamp DN50 connection follows DIN 32676/ISO 2852. The process-contact surfaces are electropolished for hygienic applications. M12 connectivity supports practical electrical installation. Gold-plated contacts improve connection durability. The sensor can be integrated into process automation systems.
The sensor is manufactured with 316L stainless steel. Wetted surfaces have a Ra value below 0.8 µm. The sensor has a 25 bar pressure rating. IP68/IP69K protection supports demanding wet environments. Shock and vibration resistance provide additional mechanical robustness.
M12 connection simplifies replacement and inspection. The clamp connection provides convenient access during service. Hygienic seals should be inspected during maintenance. The electropolished sensing surface supports effective cleaning. Proper mounting is important for consistent measurement accuracy.
