Pressure Sensor, A/C (620) EDC16

Pressure Sensor, A/C (620) EDC16

Location

Pressure sensor A/C (620)

Main task

Measures the pressure of the A/C system.

Type

Capacitive sensor with integrated electronics for signal conversion.






Connect










Function

The pressure sensor contains two metal-coated ceramic discs mounted close together. The disc closest to the pressure connection is thinner and bends when it comes under pressure. This modifies the capacitance between the metal coatings of the discs as a function of the pressure. Built into the sensor is a circuit which converts the capacitance to an analogue voltage.
