Abstract
A sensor device for measuring at least one property of a fluid medium, in particular of an exhaust gas of an internal combustion engine. The sensor device includes at least one protective housing for accommodating at least one sensor element; within the protective housing, at least one flow path being provided that allows flow therethrough by the fluid medium. The flow path has a number of at least three deflection points, where the fluid medium undergoes a directional change about an angle of at least 90°. The sensor device is highly resistant to thermal shock, while, at the same time, the sensor element has a high dynamic response.
