Surface Temperature Sensing Thermistor Probes
EI Sensor’s surface temperature sensing thermistor probes are designed for rapid thermal response, accurate thermal tracking and excellent long-term stability. Many, including the popular Clip-On Pipe Temperature sensing thermistor probe assemblies, offer moisture resistance too. The thermistor probes can operate over wide temperature ranges and are used to monitor surface temperatures in a wide range of applications including air conditioners, heat pumps, water heaters, audio amplifiers, component monitoring and consumer appliances.
With their ease of installation, EI Sensor is your go-to source for surface temperature sensing needs.
The thermistor probe assemblies shown are just some of the many styles available. Whether you need a different configuration, other sizes, materials, electrical properties…we can help. Contact our design engineers at sales@ei-sensor.com for assistance.
