g Reference pressure
h Pressure sensor
i Silicone oil
k Metal protective diaphragm
A sensor element compares the fluid pressure (b) to be measured with a reference pressure (g) in the sensor. The pressure (b) is transmitted to the actual sensor element (h) by means of a metal protective diaphragm (k) and a silicone oil layer (i).
An electronics module (a) which supplies the pressure signal in the form of an analog voltage to the control module, is located on the metal housing (d).
