摘要： A sensor for determining an oxygen content of an exhaust gas of an internal combustion engine includes a flat-plate sensing element that is inserted in a gas-tight fashion via a hybrid seal in a ceramic shaped element that is arranged in a metal housing. The seal includes a powdered sealing packing, both placed around the sensing element in a recess at one end of the ceramic shaped element and a fusible glass seal located above the powdered sealing packing. The seal achieves gas-tight and gasoline-resistant isolation or immobilization of the sensing element in the ceramic shaped element.

摘要： A housing of the device has a passage formed with two spaced open ends and with an inner circumferential shoulder. A tubular member of ion-conducting solid electrolyte material has a first closed-ended portion projecting from one of the open ends, and a second portion extending through the passage and being formed with an outer circumferential flange an axial end face of which faces the one open end and is supported by the shoulder. The interior of the tubular member is in communication with the ambient atmosphere, and an electron-conductive inner electrode is provided on an inner surface of the tubular member and conductively connected with an outside terminal portion. An electron-conductive outer electrode is provided on an outer surface of the tubular member and conductively connected with the housing. A compensating arrangement is provided on the housing fixed with reference thereto and engages the second portion of the tubular member in such a way as to compensate for differential coefficience of thermal expansion and contraction of the material of the housing and of the tubular member, respectively. This prevents relative movements of the housing and tubular member when such differential expansion or contraction occurs.
