A pressure sensor assemblage includes a housing and a pressure sensor received in an interior space of the housing. The housing has at least one gas inlet that is connected in gas-permeable fashion at least to a sub-region of the interior space of the housing. In addition, a sacrificial element is provided at the gas inlet, which element is disposed and implemented in such a way that gas flowing through the gas inlet comes into contact with a surface of the sacrificial element, which surface of the sacrificial element is provided with a silver layer. The sacrificial element has a carrier element made of an iodine- or iodide-resistant material.

Iodine-resistant pressure sensor assemblage

A pressure-compensation unit, particularly for a tank-pressure sensor in a tank of a motor vehicle. The pressure-compensation unit includes a housing lid and a gas-permeable filter diaphragm, which covers an air hole. The pressure-compensation unit includes a cap-shaped cover element, which covers the filter diaphragm.

Pressure compensation unit

A pressure compensation unit for use in a pressure sensor includes a housing which has at least one continuous channel, at least one opening being provided in a wall of the channel. The opening is connectable to a reference pressure chamber of the pressure sensor via at least one air passage in the housing. The opening is closed by at least one gas-permeable and preferably fluid-tight filter diaphragm.

A pressure sensor including a molded seal. With the aid of the molded seal the pressure sensor is held in place in an installation hole and seals the latter. The molded seal is attached to a sensor stem in a form locked manner. The molded seal is made of an elastic material and has, on its end facing away from the sensor head, a protrusion whose diameter exceeds the diameter of the installation hole. At least one annular recess is provided on the circumference of the sensor stem.

Pressure sensor mounting using a molded seal

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.

Sensor module

A sensor, in particular a pressure sensor, having a housing; a housing interiorthat contains a sensor element; electrical connecting elementsthat are routed from the outside, through a housing part, and into the housing interiorand have connecting segments, which protrude into the housing interior on an insideof the housing partat respective entry pointsand are electrically connected to the sensor element; and having a protective coveringthat covers the connecting segments and the sensor element. To prevent air bubbles from getting into the protective covering, a sealing materialis applied onto the connecting segments, at least in the region of the entry pointof the respective connecting segmentsinto the housing interiorand the partof the insideof the housing partencompassing the entry point, and the coveringis applied onto the sealing materialand the connecting segments

Sensor device

A device for measuring pressure includes a housingin which a carrierequipped with a sensor elementand electrical connection elementsis located. The housingis made up of a first housing chamberthat encloses the sensor elementand is connected with a first pressure channelof a first pressure connection. The housing also includes a second housing chamberthat is sealed off from the first housing chamberand encloses at least the electrical connection elements. The housinghas a third housing chamberthat is sealed off from the first housing chamberand the second housing chamber. The third housing chamber is connected with a second pressure channelof a second pressure connection
