The TM4331 is an industrial Pt100 temperature sensor with a 100 mm installation length for deeper process measurement. Its 1/2-inch NPT process connection provides a robust threaded interface for industrial equipment. The sensor supplies an RTD resistance signal for connection to compatible temperature evaluation equipment. A stainless-steel probe provides reliable operation in industrial process environments. It is suitable for temperature monitoring in machinery, pipelines, tanks and process systems.
Explore performance details, construction highlights, applications, and technical information in one clear overview.
The 100 mm probe length allows the TM4331 to reach deeper into process media. The sensor is designed for direct process temperature measurement. Its 1/2-inch NPT connection supports common industrial installation standards. The M12 electrical interface provides practical field connectivity. The compact design supports installation in automated machinery.
The Pt100 element provides standard RTD measurement. The operating measurement range is approximately -40...150 °C. The longer probe improves measurement access in deeper process points. The stainless-steel construction supports stable operation. External evaluation electronics convert the RTD signal into control-system data.
The 1/2-inch NPT connection supports threaded process installation. The 100 mm installation length provides deeper immersion. M12 wiring enables connection to RTD-compatible modules. The sensor can be integrated with temperature controllers and PLC input systems. Mechanical sealing should be appropriate for the installed process.
RTD sensor diagnostics are generally handled by the connected evaluation system. Open-circuit and resistance abnormalities can be detected by compatible controllers. Regular inspection of the process connection supports reliable operation. The probe should be protected from bending and mechanical shock. Calibration checks can be incorporated into scheduled maintenance.
