Explore performance details, construction highlights, applications, and technical information in one clear overview.
The TM4361 is designed for precise and reliable temperature measurement across a wide measuring range of -40 to 150 °C. It uses a Pt100 measuring element manufactured according to DIN EN 60751, Class A, ensuring accurate resistance-based temperature measurement. The sensor provides a specified accuracy of ±(0.15 K + 0.002 × |t|), making it suitable for demanding industrial process-monitoring applications. Its dynamic response time is approximately 1 second for T05 and 3 seconds for T09 under specified test conditions. This combination of measurement accuracy and fast response enables effective monitoring of temperature changes in industrial processes.
The TM4361 features a robust cylindrical stainless-steel construction developed for reliable operation in demanding industrial environments. The housing and wetted components are manufactured from 316L / 1.4404 stainless steel, providing high resistance to mechanical stress and chemical exposure. With a compact 6 mm probe diameter, the sensor can be installed in applications where space is limited. The 250 mm installation length allows the sensing element to reach the required measurement point inside tanks, pipelines, and process equipment. Its durable construction makes the sensor suitable for temperature measurement in both liquid and gas media.
The TM4361 is equipped with a 1/2" NPT external threaded process connection, allowing secure installation in compatible industrial process fittings and equipment. The threaded connection supports straightforward mechanical integration while maintaining a reliable connection in pressure-bearing applications. Its 250 mm installation length provides sufficient insertion depth for effective temperature measurement within the process medium. A minimum installation depth of 15 mm provides additional flexibility during installation. With a pressure rating of up to 160 bar / 16 MPa, the sensor is suitable for high-pressure process applications within its specified operating conditions.
The TM4361 uses a standardized 1 × M12 connector with A coding for electrical connection to compatible evaluation and automation systems. The connector contacts feature gold plating, helping provide reliable electrical conductivity and stable long-term connection performance. The sensor is intended for connection to an appropriate evaluation unit for processing and monitoring temperature measurements. Its Protection Class III electrical design provides the specified level of protection for the device. The standardized M12 interface also simplifies integration into industrial sensor, instrumentation, and automation systems.
The TM4361 is designed to operate reliably in demanding industrial environments and provides IP68 and IP69K protection against dust, water, and high-pressure cleaning conditions. The specified ambient operating temperature range is -25 to 80 °C, while the storage temperature range extends from -40 to 100 °C. The sensor is designed to withstand mechanical stresses commonly encountered in industrial installations. Its shock resistance is specified at 50 g for 11 ms, providing durability during mechanical impact conditions. In addition, vibration resistance of 5 g across 10–2000 Hz supports stable operation when installed near industrial machinery and vibrating equipment.
