A sensor device is provided for determining a pressure of a medium located inside a housing of an electrochemical energy storage. The sensor device includes a detection unit which may be or is inductively coupled to an electrically conductive layer, which is deflectable by the pressure of the medium to be determined. The detection unit is designed to inductively detect a distance, which is dependent on the pressure of the medium to be determined, between the layer and the detection unit, to determine the pressure of the medium from the distance.

Sensor device and method for determining a pressure of a medium located inside an electrochemical energy store, electrochemical energy store, and method for the manufacture thereof

A pressure measuring device for detecting a pressure to be measured of a medium, having a pressure housing; a converter situated in the pressure housing for converting a mechanical force produced by the pressure to be measured into an electrical signal; an output unit for outputting the electrical signal; a separator for separating the medium from the converter; and a transmission device for transmitting the force produced by the pressure to be measured to the converter.

Method for detecting a pressure of a medium and pressure measuring device

A device for measuring pressure, in particular for measuring high pressure, is provided, having a pressure sensor situated in a sensor housing, the sensor housing having a first sensor housing part provided with a pressure connecting piece and a second sensor housing part provided with an electric terminal. To reduce the manufacturing cost, the second sensor housing part is attached to the first sensor housing part by a connecting part situated between the first sensor housing part and the second sensor housing part, it being possible for the connecting part to be manufactured as a simple punch bent part or thin-walled tubular part, for example.

High-pressure sensor housing which is simplified by means of a connection element (also emc)

A pressure sensor for measuring the pressure in a space acted upon by high pressure. The signals detected by the pressure sensor are supplied to evaluation electronics. A sensor diaphragm is accommodated on the end of the pressure sensor pointing towards the space acted upon by high pressure. The sensor diaphragm takes the form of a steel diaphragm, to whose back side a thin, metallic layer accommodating piezoresistive measuring elements is applied. The thin, metallic layer is contacted by transmission elements and connected to the evaluation electronics.

Combustion-chamber pressure sensor having a metallic diaphragm containing a piezoresistive, thin metallic layer

A micromechanical pressure sensor and a method for producing a micromechanical pressure sensor. This pressure sensor has at least one membrane and a measuring element situated on the membrane. A pressure applied at the membrane or a pressure differential applied at the different sides of the membrane results in deformation of the membrane. Simultaneous with the deformation of the membrane, the measuring element is subjected to elastic elongation and/or compression. In a piezo-sensitive component, such elastic elongation and/or compression generates a measured variable in the measuring element, which represents the applied pressure or the applied pressure differential at the membrane. It is provided in this context that the measuring element have at least partially a NiCr(Si) layer. Due to an at least partial crystallization in the production of the micromechanical pressure sensor, this NiCr(Si) layer has more advantageous piezoelectrical characteristics than an amorphous NiCr(Si) layer.
