The sensor device (1) comprises a housing body (4), which has a flow channel (6) formed in the housing body (4). Furthermore, the sensor device (1) has a bypass (12) formed in the housing body (4), which bypass branches off from the flow channel (6) at a branching point (13). The bypass (12) has a wall having an opening. Furthermore, the sensor device (1) comprises a sensor element (S) for detecting a gas content in an environment of the sensor element (S), which is arranged at least partially in the opening in the wall of the bypass (12). The sensor element (S) is designed to detect a gas content in an environment of the sensor element (S). The sensor element (S) comprises a sensor body (SK). The sensor element (S) also comprises an electrode chamber (EK), which is formed in the sensor body (SK). The sensor element (S) comprises a heating element, which is embedded in the sensor body (SK), by means of which heating element a specified region around the electrode chamber (EK) can be heated to a specified operating temperature. The sensor element (S) has a longitudinal axis. Furthermore, the sensor element (S) comprises an inlet channel (EAK), which is coupled to the electrode chamber (EK) and which has an inlet (EA) at the surface of the sensor body (SK). Furthermore, the sensor element (S) comprises a thermal insulation sleeve (IH) on the sensor body (SK), which thermal insulation sleeve extends at least axially in the direction of the longitudinal axis over the region of the electrode chamber (EK). |
