Exhaust gas sensor for determining e.g. carbon monoxide, of exhaust gas of internal combustion engine, has discharge opening arranged based on direction of gravitational force, so that liquid in protection body is discharged through opening

摘要

The sensor (1) has a protection body (5) arranged around a sensor element (3) and including an outer chamber region (6) and an inner chamber region (7). The regions are separated by a chamber wall (13), which exhibits a chamber opening (12). The sensor element and the body are connected with a housing (2). A lateral external surface of the body exhibits a discharge opening (10) that is arranged based on the direction of the gravitational force in such a manner that a liquid in the body is discharged through the discharge opening due to the gravitational force.
