Abstract
A gas sensor includes a one-piece housing sleeve having a length dimension; an exhaust gas-side end and an opposite, exhaust gas-remote end, an inner space, an external thread, a terminal length portion which includes the exhaust gas-side end and which is exposable to an exhaust gas and a shoulder extending along an entire inner circumference of the housing sleeve at the terminal length portion thereof. A protecting sleeve which is disposed in the terminal length portion has a sealing collar seated on the shoulder of the housing sleeve. A ceramic supporting member is disposed in the inner space and has a throughgoing aperture parallel to the length dimension of the housing sleeve. The ceramic supporting member separates the inner space into a reference gas chamber and an exhaust gas chamber. The exhaust gas chamber is surrounded by the terminal length portion of the housing sleeve. A sensor element passes through and is fixedly held in the throughgoing aperture of the ceramic supporting member.
