摘要:
A gas sensor is for determining at least one physical quantity of a gas, e.g., an exhaust gas of an internal combustion engine, the gas sensor having a sensor element that is fixed in a housing of the gas sensor by a seal assembly. The seal assembly includes a sealing element, which has a ceramic and/or a metallic material. After the heat treatment, the sealing element has a maximum decrease in volume of 5 percent, or an increase in volume, based on the volume of the sealing element prior to the heat treatment.

摘要:
A gas sensor, in particular for determining the oxygen content in exhaust gases of internal combustion engines, having a housing, a sensor element having a multi-layer design which is situated in the housing, and connecting lines lead to the outside for contacting the sensor element. A contacting element of a connecting line penetrates a layer of the sensor element and part of an insulating element situated outside the sensor element. For contacting the sensor element, such a contact configuration makes it possible to directly contact the contacting element of the connecting line, which may be arranged as a contacting pin, to the printed conductor which is formed inside the sensor element.
