The TM4941 is an IFM hygienic temperature sensor designed for deeper process-temperature measurement. Its 150 mm installation length provides suitable immersion in larger tanks, vessels and sanitary process lines. The DN50 clamp connection supports hygienic installation in compatible process piping. A Pt 100 Class A sensing element provides stable and repeatable measurement. The passive RTD output connects to an external evaluation system for process monitoring and temperature control.
Explore performance details, construction highlights, applications, and technical information in one clear overview.
The TM4941 uses stainless-steel 316L construction for demanding hygienic applications. Its 150 mm probe provides deeper process immersion. The DN50 clamp connection supports secure sanitary installation. Electropolished wetted surfaces support cleanability. The M12 connector provides a reliable electrical interface to external evaluation equipment.
The Pt 100 Class A element provides reliable temperature measurement. The -40...150 °C range supports a broad range of process applications. Its 150 mm sensing length is useful for larger process vessels. The sensor provides a passive resistance signal to an evaluation unit. Fast response characteristics support monitoring of changing process temperatures.
The DN50 clamp connection supports practical hygienic process integration. Stainless-steel construction provides durability and cleanability. The M12 interface supports connection to RTD evaluation electronics. Gold-plated contacts help maintain electrical reliability. The sensor is suitable for PLC and industrial temperature-control systems.
