The TM4901 is an IFM hygienic temperature sensor designed for process-temperature measurement using a Pt 100 Class A element. Its 30 mm installation length provides compact sensing for hygienic equipment. The DN50 clamp connection supports installation in larger sanitary process pipelines. The passive RTD output is designed for connection to an external evaluation unit. Stainless-steel construction, electropolished wetted surfaces and high protection support demanding food and beverage applications. IFM specifies a DN50 clamp, 30 mm installation length, 25 bar pressure rating and -40...150 °C range.
Explore performance details, construction highlights, applications, and technical information in one clear overview.
The TM4901 uses stainless-steel 316L construction for hygienic process applications. Its DN50 clamp connection is suitable for larger sanitary process piping. The 30 mm sensing length provides compact immersion. Electropolished wetted surfaces support cleanable process installations. The M12 electrical interface provides reliable connection to external evaluation electronics.
The Pt 100 Class A element provides stable temperature measurement. Its -40...150 °C range supports a wide variety of hygienic process applications. The compact 30 mm sensing length provides quick thermal response. The passive RTD output allows connection to a compatible evaluation system. T05/T09 response is approximately 1/3 seconds.
The DN50 clamp connection supports hygienic installation in larger process lines. The stainless-steel process-contact construction supports cleanable equipment. The sensor can be connected to PLC RTD inputs or external evaluation units. Gold-plated contacts support reliable electrical transmission. The design is suitable for food, beverage and sanitary process environments.
