A sensor element compares the fluid pressure to be measured (b) in comparison with a reference pressure (g) in the sensor. The pressure (b) is transmitted to the actual sensor element (h) via a metal protective diaphragm (k) and a silicone oil layer (i). An electronic module (a) which transmits the pressure signal to the control module as an analog voltage, is located on the metal housing (d).
