A pressure sensor for measuring a pressure of a fluid medium in a measuring chamber is provided. The pressure sensor includes a sensor housing, a first pressure-sensor module for measuring at least one first pressure of the medium in a first measuring chamber, and a second pressure-sensor module for measuring at least one second pressure of the medium in a second measuring chamber. The first pressure-sensor module and the second pressure-sensor module are situated inside the sensor housing. In addition, the pressure sensor has at least one first pressure connection, which is designed for the connection to the first measuring chamber. Moreover, the pressure sensor has at least one second pressure connection, which is developed for the connection to the second measuring chamber. The first pressure connection differs from the second pressure connection.

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.

A pressure sensor module is described for determining the pressure of a measurement medium, and includes a sensor chip, a housing having a pressure connector, and a plug part for the electrical connection of the pressure sensor module. In addition, plug contacts that are electrically connected to the sensor chip are provided in the plug part. In addition, in the provided pressure sensor module it is provided that the sensor chip is capable of being loaded with the measurement medium through the pressure connector, and the pressure connector is made at least partly of a light metal.

Pressure sensor module

A pressure detection module of a pressure sensor device includes a receptacle part for receiving a carrier substrate. The carrier substrate is located on a first side with a pressure detection unit, and is inserted into the receptacle part with a second side facing away from the first side. The carrier substrate is fixed with its second side on a base of a receptacle groove. In order to construct the pressure detection module as small as possible, and to manufacture it in a cost-effective way, the receptacle part, the receptacle groove and a peripheral flange around the receptacle groove are, for example, provided with a plate-shaped design. The base has a contacting opening, through which contact surfaces of the carrier substrate, which are exposed at the contacting opening, are electrically contactable.

Sensor device

In a pressure sensor module according to the prior art, which is intended for detecting the pressure of a corrosive medium, the conventional sensor cell with a pressure sensor chip is modified in order to protect it from corrosion, which results in a large volume for a pressure-transmitting-fluid. This is disadvantageous for the calibration and for a high degree of measurement precision. In a pressure sensor module () according to the invention, a convention sensor cell () is used that has an adapter () connected to it, which has a very small volume for a pressure-transmitting medium.
