Abstract
An exhaust gas sensor (10) is disclosed which includes a sensor element (12) and a member (48). The member (48) includes a hollow tube (50) and a seal disk (58). The seal disk (58) is urged into sealing engagement with an annular surface (14) on the sensor element (12) to prevent exhaust gas from entering the interior (26) of the sensor element (12). The inner electrode (22) of the sensor element (12) extends to the annular surface (14) in an annular ring (88). The seal disk (58) is permitted to contact the inner electrode (22) about the entire periphery of the ring (88).
