| 摘要 |
The invention relates to a pressure sensor ( 1 ), comprising a housing ( 2 ), a housing element ( 3 ) which may be exposed to a pressure chamber ( 10 ), mounted on the housing ( 2 ) by means of a metallic membrane ( 5 ) and a measuring cell ( 4 ) which can indirectly measure a pressure acting on the housing element ( 3 ) and transmitted to the measuring cell ( 4 ) as a force resulting therefrom. According to the invention, said pressure sensor ( 1 ) comprises a housing element ( 3 ) embodied as a pin and projects out of the housing ( 2 ). The advantage of such an arrangement is only a small drilling to a pressure chamber ( 10 ) need be provided, in order to carry out a pressure measurement. The pin ( 3 ) need only be so long that the front end thereof, in the assembled state, approximately reaches the wall ( 11 ) of the pressure chamber ( 10 ).
