The TM4841 is an IFM hygienic temperature sensor designed for deeper process-temperature measurement. Its 150 mm installation length provides useful immersion in tanks, vessels and hygienic pipelines. The DN25...DN40 clamp connection supports sanitary process installation. A Pt 100 Class A sensing element provides stable and repeatable temperature measurement. Its stainless-steel construction and electropolished wetted surfaces support cleanable food and beverage process equipment. IFM describes this model for precise measurement in vessels, tanks and pipelines and for connection to an external evaluation unit.
Explore performance details, construction highlights, applications, and technical information in one clear overview.
The TM4841 features a robust 316L stainless-steel process-contact construction. Its 150 mm probe provides deeper immersion for larger process vessels. The clamp connection supports hygienic piping installation. Electropolished wetted surfaces provide a smooth process-contact finish. The M12 connector provides reliable connection to external evaluation electronics.
The Pt 100 Class A element provides dependable temperature measurement across the specified range. The 150 mm installation length allows the sensing point to reach deeper process locations. The sensor provides a passive RTD signal for external evaluation. Fast response characteristics support processes with changing temperatures. The sensor is suitable for liquids and gases within its operating specifications.
The clamp connection allows practical installation in compatible hygienic piping systems. Stainless-steel construction supports cleanable process equipment. The sensor can be integrated with PLC RTD modules and temperature evaluation units. Gold-plated contacts support reliable electrical signal transmission. Its design is suitable for food, beverage and hygienic process applications.
