The TM4361 is a robust IFM temperature sensor designed for accurate process-temperature measurement in industrial systems. It uses a Pt 100 Class A sensing element for stable and repeatable temperature measurement. Its 250 mm installation length provides deep immersion for tanks, vessels and process pipelines. The 1/2-inch NPT external thread supports secure installation in compatible process connections. The sensor uses a passive RTD output and can be connected to a suitable temperature evaluation unit.
Explore performance details, construction highlights, applications, and technical information in one clear overview.
The TM4361 features a cylindrical stainless-steel construction designed for demanding industrial environments. Its 250 mm probe provides extended reach into process media where deeper measurement is required. The 6 mm probe diameter allows practical installation in suitable process fittings and adapters. Stainless-steel 316L construction provides durability and good compatibility with many industrial media. The M12 connection with gold-plated contacts provides a reliable electrical interface.
The Pt 100 Class A sensing element provides dependable resistance-based temperature measurement. The sensor is designed for liquids and gases within its specified operating conditions. Its extended installation length helps position the sensing element correctly inside larger vessels and process lines. The dynamic response is suitable for applications where process temperature can change relatively quickly. The sensor must be connected to a compatible evaluation unit for temperature conversion and monitoring.
The 1/2-inch NPT external thread provides a practical threaded process connection for industrial equipment. Multiple installation adapters can be used where required by the process design. The M12 connector simplifies connection to external evaluation electronics. Gold-plated contacts support reliable signal transmission over repeated industrial operation. The sensor is suitable for integration into PLC-based temperature-monitoring systems through an appropriate evaluation module.
