摘要： The ceramic sensor body, held inside a housing by a sealing packing, is provided with a circumferential coating of an electrically insulating material in the region of the sealing packing, so that the sensor body remains potential-free with respect to the housing, even when a sealing packing is used that is made of a material having poor electrical insulating qualities. In this manner, a glass putty is used for the sealing packing, which, while having comparatively poor insulating characteristics, provides a good sealing effect at high loading capacity.

摘要： A sensor element for determining the concentration of gas components in gas mixtures, particularly for determining the oxygen concentration in exhaust gases of internal combustion engines. It contains a pump cell, which pumps oxygen into or out of a measuring gas chamber, as well as a concentration cell, which has a reference electrode situated in the reference gas channel, and has a measuring electrode. The measuring gas chamber and the reference gas channel are situated in the same layer plane of the sensor element, and are separated from each other by a partition, which is produced by applying a ceramic paste to an adjacent, solid electrolyte foil.
