Refrigerant Pressure Sensor / Switch: Description and Operation

COMPONENT PARTS

Refrigerant Pressure Sensor


DESCRIPTION

- The refrigerant pressure sensor converts high-pressure side refrigerant pressure into voltage and outputs it to VCM.
- VCM performs the cooler system protection and each engine control by the input voltage.






STRUCTURE AND OPERATION

- The refrigerant pressure sensor is a capacitance type sensor. It consists of a pressure detection area and a signal processing area.
- The pressure detection area is the variable capacity compressor. It changes the internal capacitance according to the pressure.
- The signal processing area detects the capacitance of pressure detection area, converts it into the voltage, and outputs it to VCM.
