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).
