    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： 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： 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 layered sensor element used in particular for detecting a physical variable of a measuring gas, preferably for detecting the temperature of the measuring gas or the concentration of a gas component of the measuring gas. The sensor element contains a heater printed conductor situated in a layer plane of the sensor element, the heater printed conductor including a heater and a heater lead and being embedded in an insulation. In the layer plane of the heater printed conductor, the insulation is surrounded by a sealing frame at least in some areas. The extension of the sealing frame in the direction parallel to a layer plane of the sensor element and perpendicular to the longitudinal axis of the sensor element at least in some areas amounts to at least 25 percent, preferably 30 percent to 80 percent, of the extension of the sensor element in this direction.

    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.

    摘要： A probe is described for determining an oxygen concentration in a gas mixture, in particular in the exhaust gas of internal combustion engines, having a Nernst measuring cell, which has a first electrode (Nernst electrode) which is exposed to the gas mixture to be measured via a diffusion barrier, a second electrode (reference electrode) which is exposed to a reference gas, and a solid electrolyte body arranged between the first and the second electrode, and having a pump cell, which has a first electrode (inner pump electrode) which is exposed to the gas mixture via the diffusion barrier, a second electrode (outer pump electrode) which is exposed to the gas mixture, and a solid electrolyte body arranged between the first and the second electrode. The Nernst electrode and the inner pump electrode are connected at least in some sections via a joint supply conductor to a circuit arrangement for controlling and evaluating the probe. A joint supply conductor resistor of the Nernst electrode and of the inner pump electrode is formed by a loaded voltage divider whose individual resistors are arranged so that the negative feedback of a Nernst voltage circuit and of a pump voltage circuit is optimized, in particular maximized.
