The TM4331 is an IFM Pt 100 Class A temperature sensor designed for reliable process-temperature measurement. Its 100 mm installation length provides suitable immersion for many industrial piping and process applications. The 1/2 NPT external thread provides compatibility with NPT-based process connections. The sensor produces a passive RTD resistance signal and therefore requires a suitable evaluation device or controller. Stainless-steel construction, M12 electrical connectivity and robust industrial design make it suitable for liquids, gases and process equipment.
Explore performance details, construction highlights, applications, and technical information in one clear overview.
The TM4331 uses a 100 mm sensing probe for practical process immersion. Its stainless-steel construction provides mechanical strength and suitable process compatibility. The 1/2 NPT external thread provides a robust threaded installation solution. The M12 connection provides reliable electrical integration with compatible RTD electronics. Its cylindrical probe design simplifies installation into industrial piping and machinery. The passive sensor architecture keeps the sensing element separate from the signal-processing electronics.
The Pt 100 Class A sensing element provides stable and repeatable temperature measurement. The 100 mm length enables the sensing element to reach suitable measurement locations within the process. The sensor provides a resistance-based RTD output rather than a powered analogue transmitter signal. A compatible controller converts the resistance value into process temperature. Fast response characteristics support dynamic temperature monitoring. Installation conditions, wiring and evaluation electronics influence overall system accuracy.
The TM4331 is designed to connect to a compatible RTD input or evaluation system. Its M12 electrical interface provides a convenient industrial connection. Gold-plated contacts support reliable electrical performance. No integrated 4–20 mA transmitter or IO-Link electronics are required at the sensor itself. The connected evaluation device provides signal processing and temperature indication. This configuration is useful where centralised temperature evaluation is preferred.
The TM4331 is suitable for process piping, machinery and industrial temperature monitoring. Its 100 mm sensing length provides useful immersion for liquid and gas applications. The 1/2 NPT connection supports compatible threaded process systems. Stainless-steel construction provides durability in suitable industrial environments. High protection supports demanding installations when the connector and wiring are correctly installed. The sensor is suitable for cooling, heating, pump and process-skid applications.
