The TM4441 is an IFM temperature sensor with a 150 mm installation length for reliable process-temperature measurement. It uses a Pt 100 Class A sensing element for stable and repeatable temperature measurement. The G 1/2 external thread provides a secure process connection for suitable industrial installations. Its longer probe allows the sensor to reach deeper into tanks, vessels and process pipelines. The passive RTD output is intended for connection to a suitable external evaluation unit.
Explore performance details, construction highlights, applications, and technical information in one clear overview.
The TM4441 combines a cylindrical stainless-steel body with a 150 mm sensing probe. Its extended probe provides useful immersion in deeper process applications. The 6 mm probe diameter supports installation through compatible process adapters. Stainless-steel 316L construction offers mechanical durability. The M12 connector with gold-plated contacts provides dependable electrical connection.
The Pt 100 Class A element provides accurate resistance-based temperature measurement. The 150 mm length provides deeper sensing than shorter variants in the same family. The sensor is suitable for liquids and gases within its specified range. Its dynamic response allows it to follow changing process temperatures. External evaluation electronics are required to convert the RTD signal into temperature information.
The G 1/2 external thread allows straightforward installation into compatible process equipment. The sensor can be used with suitable adapters where required. The M12 interface provides a practical connection to temperature evaluation units. The passive sensor design keeps signal processing separate from the sensing element. This is useful in centralised industrial automation architectures.
