Abstract
Aspects relate to a sensor device 1 and a method for detecting properties of a medium having an inner space bounded by a wall. An open measuring capacitor is arranged in the inner space. A coupling capacitor with at least two coupling capacitor areas is arranged on the wall in such a way that at least a part of the wall is arranged between an inner coupling capacitor area and an outer coupling capacitor area. The inner coupling capacitor area is connected to the measuring capacitor 10.
Claims11
A sensor device for detecting properties of a medium, comprising:
- a wall delimiting an inner space;
- an open measuring capacitor which is arranged in the inner space;
- and
- a coupling capacitor with at least two coupling capacitor areas, wherein in between an inner coupling capacitor area and an outer coupling capacitor area at least part of the wall is arranged;
- wherein the inner coupling capacitor area is connected to the measuring capacitor,
- wherein the measuring capacitor comprises a capacitor comb configured to accept a flowing medium between teeth of the capacitor comb, wherein the capacitor comb comprises a rear panel and at least two capacitor comb areas which are arranged at an angle to the rear panel and parallel to each other,
- wherein the rear panel of the capacitor comb is the inner coupling capacitor area.
