Patent ID: 7472600

Claim:
A pressure sensor ( 1 ) for measuring the pressure within a pressure chamber ( 10 ) defined by a wall ( 11 ) of a work piece ( 14 ), the sensor ( 1 ) comprising: a housing ( 2 ) configured to be mounted to the wall ( 11 ) of the work piece ( 14 ), a metallic membrane ( 5 ) defined within the housing ( 2 ), a housing element ( 3 ) defining a pin extending slidably through said membrane ( 5 ) and having a first end disposed within the housing ( 2 ) and a second end which projects out of the housing ( 2 ) and is exposed to the pressure chamber ( 10 ) when the housing ( 2 ) is mounted to the wall ( 11 ) of the work piece ( 14 ), and a measuring cell ( 4 ) disposed within the housing ( 2 ) in a manner by which the cell ( 4 ) can indirectly measure a pressure acting on the first end of the housing element ( 3 ) and transmitted to the measuring cell ( 4 ) as a force resulting therefrom.
