The TM4541 is an IFM Pt 100 Class A temperature sensor designed for deeper process-temperature measurement. Its 150 mm installation length provides useful immersion in process vessels, pipelines and industrial equipment. The G 1/2 external thread provides a reliable threaded process connection. The passive RTD output is designed for connection to an external evaluation unit. Its stainless-steel construction and high ingress protection make it suitable for demanding temperature-monitoring applications.
Explore performance details, construction highlights, applications, and technical information in one clear overview.
The TM4541 uses a cylindrical stainless-steel body with an extended 150 mm sensing probe. The 6 mm probe diameter supports practical installation in compatible process fittings. Stainless-steel 316L construction provides mechanical durability. The threaded G 1/2 process connection supports secure mounting. The M12 connector provides a robust electrical interface.
The Pt 100 Class A sensor provides stable temperature measurement. Its -40...150 °C range covers many industrial process applications. The 150 mm length allows deeper immersion into tanks and process lines. Fast dynamic response supports applications with changing process temperatures. The sensor requires an external evaluation unit for temperature indication.
The G 1/2 threaded connection supports installation in suitable process equipment. Adapters can be used where different connection requirements exist. The M12 connector provides reliable connection to external RTD electronics. Gold-plated contacts support dependable signal transmission. The sensor is suitable for PLC and industrial temperature-control systems.
