Amphenol Advanced Sensors Inline Flow-Through Temperature Sensor for automotive and industrial applications monitors the temperature of a fluid that passes through it. This temperature reading is then inputted into a system control module that uses the temperature reading to control the overall system temperature via a control loop. The sensor can monitor engine temperature, heater temperature, industrial supply temperature, and more. The sensor features high sensitivity, fast response time, and a -40ºC to +120ºC operating temperature.
