The TM4511 is an IFM Pt 100 Class A temperature sensor designed for accurate temperature measurement in industrial process applications. Its 50 mm installation length provides practical immersion for process pipes and equipment. The G 1/2 external thread with sealing cone provides secure process installation. The sensor provides a passive RTD signal for connection to an external evaluation unit. Its stainless-steel construction, M12 connector and IP68/IP69K protection support demanding industrial environments. IFM specifies -40...150 °C, 160 bar pressure rating and 1/3 second T05/T09 response for this model.
Explore performance details, construction highlights, applications, and technical information in one clear overview.
The TM4511 uses a cylindrical stainless-steel body designed for industrial process measurement. Its 50 mm probe provides a useful balance between compact installation and immersion depth. The 6 mm probe diameter allows installation in suitable process fittings. Stainless-steel 316L wetted materials provide durability and process compatibility. The M12 connection uses gold-plated contacts.
The Pt 100 Class A element provides stable and repeatable temperature measurement. The sensor covers -40...150 °C and is suitable for liquids and gases. The 50 mm installation length allows the sensing element to reach into the process medium. Its T05/T09 response is approximately 1/3 seconds. The passive RTD signal is evaluated by a compatible external temperature unit.
The G 1/2 external thread provides a secure process connection. The sealing cone supports suitable process sealing arrangements. The M12 A-coded connector provides convenient electrical integration. Gold-plated contacts help maintain reliable signal transmission. The sensor can be integrated with PLC temperature modules and industrial controllers.
