  • Exhaust gas sensor
    Patent number: 10866207
    Abstract: An exhaust gas sensor for detecting a measurement gas component, having a ceramic sensor element fixed in a housing, and a double-walled protective pipe having outer and inner protective sleeves, the inner sleeve enclosing a gas chamber into which the sensor element extends with a segment at the measurement gas side, in the direction of a longitudinal axis of the sensor, and an annular chamber being formed between the outer and inner protective sleeves. The outer sleeve has a cladding surface having at least one opening configured as a swirling element, through which measurement gas can move into the annular chamber with rotation about a longitudinal axis of the sensor, and the inner sleeve has at least one opening that is adjusted and/or functionally optimized, as to a sensitive region of the sensor element, through which opening the measurement gas can move from the annular chamber into the gas chamber.
