    摘要: For the reduction of internal stresses and formation of cracks caused thereby, an exhaust gas probe includes two measuring electrodes separated by a solid electrolyte layer made substantially of ZrO2 and a circuit-board conductor layer for electrically heating the solid electrolyte layer. The circuit-board conductor layer is firmly connected to the solid electrolyte layer via a first sealingly sintered insulating layer made of an Al2O3-containing material. A pore-forming material is added to the Al2O3-containing material before. sintering.

    摘要: A gas sensor has improved electrical properties. In the top view of the layer planes of the body of the sensor, printed circuit traces for electrodes are arranged outside of cavities in the body, e.g., outside of the reference air duct. Furthermore, the electrodes are enlarged in the direction of the exhaust-side end of the sensor. Also, the printed circuit traces have an increased layer thickness or are formed as a double layer.

    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 heating device for a sensor element of a gas sensor, in particular for use in exhaust gas analysis of internal combustion engines, has a heating element, which has an electrical resistor layer. The heating element is electrically insulated from at least one solid electrolyte layer by a layer containing barium and/or strontium and/or calcium. For this purpose, the heating element is embedded in a first insulator, which is adjoined by a second insulator. The first insulator has a higher barium and/or strontium and/or calcium content (expressed in weight percentage) than the second insulator.

    摘要: A sensor element is provided for determining at least one physical property of a gas mixture in at least one gas chamber, which includes at least one component to be identified, especially oxygen, and at least one oxidizable component, especially a combustion gas. The sensor element has at least one first electrode, at least one second electrode, and at least one solid electrolyte connecting the at least one first electrode and the at least one second electrode. The at least one second electrode has a lower catalytic activity, particularly a lower electrocatalytic activity with respect to the at least one oxidizable component than the at least one first electrode.
