Industrial Temperature Sensor


EM500-PT100 equips with a highly accurate temperature sensor PT100, the platinum resistance temperature detector offers much most stable and precise temperature measurement from -200 to 800°C.

PT100 Sensor

Vibration-resistant construction

In three-wire circuit

Customizable temperature detection range (-200 ~ 800°C)

Terminal heads available in straight tube, armoured, SMT, threaded, magnet

Features, Benefits And Applications >>>

In the process industry, PT100 sensor is universally and broadly used to measure extreme temperatures covering a wide range from -200 to +800°C. Also, the sensor type indicates two important factors about the sensor.

Smart Wine Cellar
Boiler Temperature Monitoring

Temperature Monitoring for Industrial Boilers >>>

In industrial scenes, as the operating time of mechanical equipment, such as an industrial boiler, becomes longer during operation, the temperature will increase continuously. Therefore, the need of using an industiral temperature sensor to monitor the temperature of the equipment in time can detect problems early and prevent safety accidents.
