The TM4341 is an IFM Pt 100 Class A temperature sensor designed for reliable process-temperature measurement. Its 150 mm installation length provides deeper immersion for tanks, vessels and process pipelines. The 1/2 NPT external thread allows installation in compatible threaded process systems. As a passive RTD sensor, it provides a resistance signal to an external evaluation device rather than generating a 4–20 mA output itself. Its stainless-steel construction and M12 electrical connection support reliable operation in demanding industrial temperature-monitoring applications.
Explore performance details, construction highlights, applications, and technical information in one clear overview.
The TM4341 uses a 150 mm sensing probe for deeper temperature measurement. Stainless-steel construction provides a robust process-contact solution for suitable media. The 1/2 NPT external thread supports compatible industrial process installations. The extended probe allows the sensing element to reach deeper into vessels and process lines. The M12 electrical connection provides reliable integration with external RTD electronics. The passive construction simplifies the sensing architecture while allowing centralised signal processing.
The Pt 100 Class A RTD element provides stable and repeatable temperature measurement. The 150 mm installation length provides useful immersion for larger vessels and process equipment. The sensor delivers a resistance signal that is evaluated by a compatible controller. The measurement principle follows the standard Pt 100 RTD approach. Fast response characteristics help the sensor follow process-temperature changes. Overall system accuracy depends on sensor installation, wiring and the connected evaluation unit.
The TM4341 connects to an external RTD evaluation system through its M12 electrical interface. Gold-plated contacts support reliable electrical connection. The sensor does not include an integrated 4–20 mA transmitter or IO-Link communication electronics. The connected controller performs temperature conversion and signal processing. This makes the sensor suitable for centralised PLC and automation architectures. It can be combined with compatible temperature evaluation modules according to system requirements.
The TM4341 is suitable for tanks, vessels, pipelines and industrial process machinery. Its 150 mm sensing length is useful where deeper immersion is required. The 1/2 NPT connection provides compatibility with suitable threaded process installations. Stainless-steel construction supports demanding industrial environments. High ingress protection supports reliable operation when installed correctly. Typical applications include cooling systems, heating systems, pumps and process skids.
