The TM4541 is a hygienic RTD temperature sensor designed for accurate temperature measurement in process installations. It uses a Pt100 Class A element and provides a 150 mm installation length for deeper temperature measurement. The G 1/2 process connection with sealing cone supports compatible hygienic process installations. Stainless-steel construction, high ingress protection and rapid response make it suitable for demanding industrial environments. The M12 connection provides a practical interface for compatible evaluation and automation systems.
Explore performance details, construction highlights, applications, and technical information in one clear overview.
The TM4541 is intended for process temperature measurement where an extended probe length is required. Its 150 mm installation length allows the sensing element to reach further into tanks, vessels and process lines. The Pt100 Class A element provides repeatable resistance-based temperature measurement. The hygienic design is suitable for applications involving liquids and gases. Its robust construction supports continuous industrial operation.
The sensor operates across a -40 to 150 °C measuring range. Its Pt100 element follows DIN EN 60751 Class A requirements for accurate RTD measurement. The 6 mm probe construction supports efficient heat transfer from the process medium to the sensing element. Fast dynamic response allows temperature changes to be detected without excessive measurement delay. This makes the sensor suitable for temperature control and monitoring applications.
The G 1/2 external thread provides a secure mechanical interface through a compatible process fitting or adapter. The sealing-cone arrangement supports hygienic installation and reliable process sealing. The 150 mm installation length is useful for larger vessels and deeper process points. The M12 connection simplifies electrical integration and replacement. The sensor can be connected to suitable temperature evaluation equipment.
The sensor uses high-grade stainless steel for mechanical and corrosion resistance. The wetted construction is designed for hygienic process applications. IP68/IP69K protection supports demanding industrial and washdown environments. The sensor is designed for an ambient temperature range of -25 to 80 °C. Shock and vibration resistance improve suitability for industrial machinery.
The RTD sensing principle allows straightforward evaluation through compatible temperature measurement equipment. The M12 connector supports efficient maintenance and sensor replacement. Process connections should be periodically checked for proper sealing and mechanical condition. The probe should be kept free from process deposits that could influence thermal response. Correct installation depth and suitable process adapters help maintain consistent measurement performance.
