Pressure sensor for hydraulic media in motor vehicle braking systems is sealed tight on all sides and has no outwardly fed electrical contacts or lines

摘要

The device has a membrane (1) that can be deflected and/or deformed by pressure, a closed cavity (6) below the membrane, especially at least partly filled with gas or a gas mixture, a supporting frame (2) for the membrane that closes the edge region of the membrane with respect to a base (3) in a sealed manner and at least one pressure measurement transducer that converts membrane deflection and/or deformation into an electrical signal. The pressure sensor is sealed tight on all sides and has no outwardly fed electrical contacts or lines.
