Drucksensoreinheit, insbesondere für die Kraftfahrzeugtechnik

摘要

The invention relates to a pressure sensor unit (1), especially for automotive engineering, comprising a housing (3) in which a pressure measuring cell (5) is placed. Said cell is supplied with a pressure medium by means of an inlet (15) in the housing (3) which presents junction contacts (37) leading towards the outside. The pressure measurement cell (5) comprises a measuring cell housing (9) with a recess (17) into which a pressure sensor (21) is placed and which is filled as far as the inlet (29) by pressure transfer medium (27) which is applied to the sensor (21). A separating membrane (31) is provided in order to separate the pressure medium from the pressure transfer medium (27) and seals the inlet (29) wherein said membrane(31) is placed in order to seal the inlet (29) between one or several outside surfaces of the measuring cell housing (9) and the interacting inside surfaces of the housing (3) of the pressure sensor unit (1), and a tight seal of the inlet (29) of the measuring cell (5) is produced by exerting sufficient pressure between the interacting outer and inner surfaces.
