The TM4101 is an IFM RTD temperature sensor designed for direct process-temperature measurement using a Pt 100 Class A sensing element. Its 25 mm installation length provides a compact sensing solution for applications with limited insertion depth. The G 1/4 process connection allows installation into compatible industrial equipment and piping. Unlike an electronic transmitter, the TM4101 is a passive temperature sensor that requires a suitable evaluation unit. Its stainless-steel construction, M12 connection and high protection make it suitable for demanding liquid and gas temperature applications. IFM lists TM4101 in its probe-sensor family with a process connection for direct temperature measurement.
Explore performance details, construction highlights, applications, and technical information in one clear overview.
The TM4101 features a compact 25 mm sensing probe for short-depth temperature measurement. Stainless-steel construction provides mechanical durability and process compatibility for suitable media. The G 1/4 process connection allows direct mounting into compatible process fittings. The M12 electrical connector provides reliable connection to a suitable evaluation device. Its compact cylindrical form is suitable for machinery and process piping. The passive construction means signal conditioning is performed externally.
The TM4101 uses a Pt 100 Class A RTD element according to DIN EN 60751. The sensor provides resistance-based temperature measurement for compatible controllers and evaluation systems. Its compact 25 mm installation length is useful for shallow measurement points. The RTD element provides stable and repeatable measurement when correctly installed. Fast dynamic response helps the sensor follow process-temperature changes. Final system accuracy depends on the sensor, evaluation electronics, wiring and installation conditions.
The TM4101 does not function as a standalone 4–20 mA transmitter. Instead, its Pt 100 signal is connected to a compatible RTD input or evaluation unit. The M12 connector provides a convenient industrial connection. Gold-plated contacts support reliable electrical transmission. The connected controller performs signal evaluation and temperature conversion. This architecture is suitable for applications where the evaluation electronics are located remotely.
The TM4101 is suitable for temperature measurement in machinery, piping and process equipment. Its compact 25 mm length is useful where available installation depth is limited. Stainless-steel construction supports appropriate liquid and gas applications. High ingress protection supports industrial environments when correctly connected and installed. It can be used in pumps, process skids, cooling systems and heating equipment. The sensor should be matched with a compatible RTD evaluation system.
