Refrigerant Pressure Sensor / Switch: Description and Operation

Refrigerant Pressure Sensor

The refrigerant pressure sensor is installed at the liquid tank of the air conditioner system. The sensor uses an electrostatic volume pressure transducer to
convert refrigerant pressure to voltage. The voltage signal is sent to ECM, and ECM controls cooling fan system.
