Abstract
A pressure sensor for a motor vehicle includes a sensor housing and a base. A pressure bore through the base leads to a pressure space delimited on one side by the base and on the opposite side by a diaphragm connected sealingly to the base. An actuating element is carried on a side of the diaphragm facing away from the pressure space. The actuating element actuates a sensor element in the sensor housing via a non-contact actuation. For protection against leakage due to a break in the diaphragm, a sealing cap surrounds the diaphragm and the actuating element and is sealingly connected to the base.
Claims5
A pressure sensor for a motor vehicle, comprising:
- a sensor housing having a sensor element;
- a base arranged on said sensor housing and having a bore therethrough;
- a diaphragm connected to said base with a sealed connection, wherein a pressure space in operative connection with said bore is defined by said base and said diaphragm;
- an actuating element arranged on a side of said diaphragm facing away from said pressure space for non-contact actuation of said sensor element;
- and
- a sealing cap surrounding the side of said diaphragm facing away from said pressure space and said actuator and connected to said base with a sealed connection, said sealing cap being arranged between said the side of said diaphragm facing away from said pressure space and said sensor housing.
