Abstract:
A capacitive fluid pressure transducer ( ) has a sensing element ( ) received in an electrically conductive cup-shaped shield member ( ) which is crimped onto the base of an electrical connector ( ). A conditioning circuit ( ) is received in a circuit chamber formed between the sensor element and the connector and is provided with a tab carrying a conductive trace for electrical connection of the shield member with the circuit. The shield member is received in an electrically insulating sleeve ( ) which in turn is received in a cavity formed in a metallic, high strength hexport housing so that the shield member is electrically isolated from the hexport housing. A gasket ( ) disposed between the sensing element ( ) and the bottom wall of the shield member may be formed of electrically conductive material to provide a conductive path electrically connecting a conductive coating on the pressure sensing surface of the sensing element with the conditioning circuit to provide fluid shift correction.
