Refrigerant/ AC Coolant Temperature Sensor

Thermometrics automotive Refrigerant/ AC Coolant Temperature Sensor measures the refrigerant temperature both at the high-pressure side and low-pressure side in an air-conditioning (A/C) system. This automotive coolant temperature sensor is used to detect the operating temperature of the A/C system to determine operating conditions and potential system failures.
