ABSTRACT:
A sensor system utilizing a Bourdon tube to generate a force as a function of pressure to deflect a diaphragm in a capacitor device where the diaphragm varies capacitance values of the capacitor device as a function of the applied force. The capacitor device is an essentially integral circularly shaped construction of quartz material in which the diaphragm is attached to a tubular quartz member. A metal member having a similar coefficient of temperature expansion to the coefficient of the quartz is used to couple the diaphragm to the Bourdon tube.
