Abstract

A pressure sensor module having a sensor housing which includes a housing part in which electrical conductors are partially embedded, the sensor housing being provided with a first cavity, in which a sensor system is situated, and a second cavity which is sealed against the first cavity and in which is provided at least one capacitor, and the first cavity being provided with a receptacle part having a receptacle formed by a peripheral wall, the sensor system being inserted into this receptacle and covered by a protective covering filled into the receptacle. The sensor system is contacted with connecting elements provided on the receptacle part, these connecting elements being directly connected to connecting sections of the electrical conductors; and the at least one capacitor provided in the second cavity is connected to at least one of the electrical conductors via an electrically conductive material.
