Sensor device for detecting at least the moisture of a flowing fluid medium

A sensor device for detecting at least one property of a flowing medium, comprising:

• at least one moisture sensor;
• and
• at least one application device for applying the flowing fluid medium to the moisture sensor, wherein the application device includes at least one diaphragm and at least one protective device which has at least one guide rib structure;
• wherein the guide rib structure includes multiple guide ribs which are arranged in one of:
• a longitudinal arrangement in which the guide ribs are situated essentially in parallel to a main flow direction of the flowing fluid medium;
• a transverse arrangement in which the guide ribs are situated essentially perpendicularly with respect to a main flow direction of the flowing fluid medium;
• a radial arrangement in which the guide ribs are situated radially with respect to one another;
• a secantial arrangement in which the guide ribs are situated secantially with respect to a virtual circle;
• and
• a labyrinthine arrangement in which the guide ribs form a labyrinthine structure in which the labyrinthine structure diverts the flowing fluid medium, which acts on the moisture sensor, multiple several times.
