Abstract
A pressure sensor of a pressure-sensor module is connected to a wet space in a vehicle door by a through-passage channel of a sealing cushion and a connecting branch, which is guided with sealing action through a partition. A housing of the sensor module is located in a dry space. An interior of the housing and the dry space are sealed in relation to the interior of the connecting branch, with the result that a water-tightness of the housing, in which a printed circuit board and electronic components are accommodated, does not have to meet high requirements.
Claims9
A sensor module to be fitted on a wall having an opening formed therein, the sensor module comprising:
- a housing to be disposed in the wall and having a housing interior;
- a cover attached to said housing;
- a pressure sensor disposed in said housing and having a pressure-sensitive sensor surface;
- a sealing cushion for sealing said housing interior from the environment, said sealing cushion having a through-passage channel formed therein connecting said pressure-sensitive sensor surface to the environment;
- and
- a socket connecting said through-passage channel to the environment through the opening of the wall, said socket having an end butting with sealing action against said sealing cushion, and said sealing cushion being clamped inbetween said socket and said pressure sensor and pressing with sealing action against said pressure sensor.
