The TM4431 is an IFM Pt 100 temperature sensor designed for reliable process-temperature measurement. Its 100 mm installation length provides useful immersion for process pipes, vessels and industrial equipment. The G 1/2 external thread enables secure installation into compatible process connections. The sensor provides a passive RTD signal for connection to an external evaluation system. Its stainless-steel construction and industrial M12 connector make it suitable for continuous temperature monitoring.
Explore performance details, construction highlights, applications, and technical information in one clear overview.
The TM4431 uses a cylindrical stainless-steel probe designed for industrial process applications. Its 100 mm sensing length provides more immersion than compact 50 mm versions. The 6 mm probe diameter supports flexible process installation. Stainless-steel 316L construction provides durability and suitable media compatibility. The M12 connection provides a reliable interface to the connected temperature evaluation system.
The Pt 100 Class A element provides stable and repeatable temperature measurement. The 100 mm probe allows the sensing element to reach deeper into process media. Its passive resistance output is suitable for compatible RTD evaluation equipment. The sensor responds quickly enough for many process-temperature monitoring applications. Correct immersion and process installation help ensure representative temperature measurement.
The G 1/2 threaded connection allows simple installation in compatible industrial equipment. Suitable adapters can provide additional process-connection flexibility. The M12 connector supports reliable connection to external electronics. The sensor does not require its own transmitter supply. This architecture is useful where temperature evaluation is centralised in a PLC or controller.
