A device for measuring a pressure and a temperature of a fluid medium flowing in a duct, the device including a pressure sensor element; a temperature sensor having a temperature sensor element; a housing that has a connecting piece, the connecting piece being insertable into the duct in an insertion direction, the connecting piece having an interior chamber, the interior chamber having an opening through which the interior chamber may be exposed to the fluid medium; and a carrier substrate, the pressure sensor element being connected electrically and mechanically to the carrier substrate. In order to increase the service life of the temperature sensor, and in order to allow temperature measurement that is as accurate as possible, it is provided, in this context, that the carrier substrate be positioned substantially parallel to the insertion direction in the interior chamber of the connecting piece, the interior chamber extending along the insertion direction, and it is provided that the temperature sensor be connected electrically and mechanically to the carrier substrate.

Device for measuring a pressure and a temperature of a fluid medium flowing in a duct

A method is described for producing a pressure sensor assembly, the pressure sensor assembly having a sensor housing element having a pressure sensor and a base housing element, which have a continuous recess accommodating the pressure sensor and are welded to each other. It is provided that, after the welding, in the area of the welding connection, the recess of the base housing element and/or the sensor housing element is enlarged by material removal. A pressure sensor assembly is also described.

Method for producing a pressure sensor assembly and pressure sensor assembly

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 method for manufacturing a pressure sensor having a pressure transducer, a pressure-measuring cell having a pressurizable diaphragm as well as a transducer body. The transducer body is manufactured in one piece by a metal powder injection molding process and a subsequent sintering process. Further, a pressure sensor manufactured by the method.
