High Pressure Sensor / Switch: Description and Operation
High Pressure Sensor
High Pressure Sensor
Purpose and Operation
A temperature sensor is installed in the high pressure refrigerant line between the condenser and evaporator. The sensor is located in the plenum
towards the left side of the heat exchanger housing.
The sensor senses the temperature of the refrigerant and sends a corresponding NTC resistance signal to the control panel head. From this signal, the
control panel head can calculate refrigerant pressure. If the high pressure exceeds a predetermined level, the A/C compressor will be shut off to
prevent damage from overpressure.
