Abstract: A device for detecting at least one property of a fluid medium, and a method for its production. The method includes a) providing at least one housing, the housing having at least one electrical contact; introducing at least one sensor element for detecting the property into the housing; c) providing at least one pressure-pipe tube, the pressure-pipe tube including at least one contacting element; d) bringing the contacting element into contact with the sensor element in such a way that an electrical connection is established between the contacting element and the sensor element; and e) introducing at least one circuit substrate into the housing in such a way that the circuit substrate is electrically connected to the electrical contact of the housing and to the sensor element, the housing and the pressure-pipe tube being produced as separate components.

Abstract: A pressure sensor for recording a pressure of a fluid medium in a measuring cell. The pressure sensor includes a sensor housing, at least one first pressure sensor element for measuring a pressure of the medium, and a drive and/or evaluation circuit for outputting a signal indicative of a pressure acting on the first pressure sensor element. The drive and/or evaluation circuit is configured on or in a circuit substrate disposed within the sensor housing. The first pressure sensor element is configured on or in the circuit substrate and is separated from the fluid medium by at least one first separating membrane.

Abstract: A method is described for electrically connecting a coaxial conductor to a circuit carrier, in particular a printed circuit board. The circuit carrier has a top side and a bottom side, and printed conductors are situated at least on the top side of the circuit carrier. The coaxial conductor also includes an inner conductor and an outer conductor, the coaxial conductor being led, at least partially, from the bottom side of the circuit carrier through a feedthrough provided in the circuit carrier. In addition, at least one first contact conductor is used for electrically connecting the outer conductor to at least one first printed conductor of the circuit carrier, and at least one second contact conductor is used for electrically connecting the inner conductor to at least one second printed conductor of the circuit carrier. The first and the second contact conductors each have a press-in connection at at least one of their contact points with the circuit carrier or with the coaxial conductor.
