Claim:
1. A sensor device for measuring at least one property of a fluid medium, comprising: at least one protective housing for accommodating at least one sensor element, wherein within the protective housing, at least one flow path is provided that allows flow therethrough by the fluid medium, the flow path having at least three deflection points where the fluid medium undergoes a directional change about an angle of at least 90°; wherein an inner housing surrounds the sensor element, the inner housing being at least partially surrounded by an outer housing, the outer housing surrounds the inner housing at least partially in a way that forms an intermediate space, the outer housing having at least one inlet opening for the fluid medium, the inner housing having at least one access opening for the fluid medium from the intermediate space, the flow path extending from the inlet opening across the intermediate space to the access opening; wherein the outer housing is at least partially present in the form of a cylinder that is designed to include a curved surface area, the inlet opening being located in the curved surface area; wherein the outer housing forms a hollow space into which the inner housing is introduced in a fixed form; wherein a middle protective housing is positioned in the intermediate space between the outer housing and the inner housing, the flow path extends in the intermediate space through a region around the middle protective housing, and at least two of the deflection points is present in the region; and wherein the middle protective housing is spaced from the inner housing so that the middle protective housing does not directly contact the inner housing.
