ABSTRACT:
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.
