Abstract

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.
