Abstract
A sensor system having a sensor element, a housing in which sensor element is situated and which seals the sensor element from the outside world, at least one first electrical contact element which is electrically coupled with the sensor element; a plug connector, which has at least one second electrical contact element, and at least one spring element which is coupled between the at least one second electrical contact element and the at least one first electrical contact element for electrical contacting, so that the sensor element is electrically connected to the second electrical contact element of the plug connector.
Claims10
A sensor system, comprising:
- a sensor element;
- a housing in which sensor element is situated and which seals the sensor element from the outside world;
- at least two first electrical contact elements which are electrically connected to the sensor element;
- a plug connector which has at least two second electrical contact elements;
- at least two spring elements which are coupled between the at least two second electrical contact elements and the at least two first electrical contact elements for electrical contacting, so that the sensor element is electrically connected to the second electrical contact elements of the plug connector;
- and
- a second seal which is situated between a pressure connection and the housing, wherein the at least two spring elements exert vertical pressure on the second seal, so that the second seal creates a hermetic sealing which separates a medium under pressure to be measured from the first and second electrical contact elements, and wherein the at least two first electrical contact elements are passed through a respective at least two first housing openings in the housing.

A method for manufacturing a sensor system, comprising:
- situating a sensor element, the sensor element including a pressure sensor element, in a housing which seals the sensor element from the outside world, the housing having a second housing opening, via which the sensor element is connected to the outside world;
- electrically contacting at least two first electrical contact elements with the sensor element;
- testing functionality of the sensor element in the housing;
- after the testing, connecting a plug connector having at least two second electrical contact elements to the housing via at least two spring elements which are coupled between the at least two second electrical contact elements and the at least two first electrical contact elements, so that the sensor element is electrically connected to the second electrical contact elements of the plug connector;
- and
- connecting a pressure connection which has a pressure channel to the housing, so that a medium is conductible through the pressure channel and the second housing opening to the sensor element, wherein
- a second seal is placed between the pressure connection and the housing, and the at least two spring elements exert vertical pressure on the second seal, so that the second seal creates a hermetic sealing which separates the pressure channel from the first and second electrical contact elements, and
- the at least two first electrical contact elements are passed through a respective at least two first housing openings in the housing.
