The TM4931 is an IFM hygienic temperature sensor with a 100 mm installation length for reliable process measurement. It uses a Pt 100 Class A element for stable resistance-based temperature sensing. The DN50 clamp connection provides hygienic installation for larger process piping. The 100 mm probe provides useful immersion in tanks and vessels. Its passive RTD output connects to an external evaluation unit for PLC and temperature-control applications.
Explore performance details, construction highlights, applications, and technical information in one clear overview.
The TM4931 features a stainless-steel 316L cylindrical construction. Its 100 mm installation length provides deeper sensing in process equipment. The DN50 clamp connection supports compatible sanitary piping. Electropolished wetted surfaces provide a smooth process-contact finish. The M12 connector with gold-plated contacts supports reliable electrical connection.
The Pt 100 Class A element provides reliable temperature measurement across -40...150 °C. The 100 mm sensing length provides useful immersion for process vessels. The sensor generates a passive resistance signal for external evaluation. Its fast response supports monitoring of changing process temperatures. Correct installation and evaluation electronics help maintain system accuracy.
The DN50 clamp connection allows secure hygienic installation. Stainless-steel construction supports cleanable process equipment. The M12 connection allows integration with external RTD evaluation electronics. Gold-plated contacts support dependable signal transmission. The sensor is suitable for PLC-based temperature-monitoring systems.
