    摘要: An electrochemical gas sensor for determining the concentration of gas components in a gas mixture, in particular for determining NOx and HC. The gas sensor includes a first measuring gas space which is connected to the measuring gas, and a second measuring gas space which is connected to the first measuring gas space by a connecting channel. Furthermore, a first electrode and a second electrode, arranged in the first measuring gas space, and at least one third electrode arranged in the second measuring gas space, and at least one fourth electrode are provided. The two measuring gas spaces are arranged in layer planes on top of one another and are separated from one another by at least one oxygen ion conducting layer, the connecting channel passing through the oxygen ion conducting layer.

    摘要: A sensor element is described for determining a physical property of a measuring gas, in particular the pressure or the concentration of a gas component in a gas mixture, in particular in the exhaust gas of an internal combustion engine. The sensor element has an electrode exposed to the measuring gas and a reference electrode exposed to a reference gas, ambient air in particular, through a porous volume. The two electrodes are separated from one another by a solid electrolyte. To avoid premature aging of the reference electrode as a result of deposits of foreign substances contained in the reference gas or of chemical interactions caused by the foreign substances, the volume material is selected with respect to its physical and chemical properties in such a way that the foreign substances are bound in the volume and/or are subjected to a chemical reaction.

    摘要: A planar electrochemical probe includes a probe body laminated together from a plurality of solid electrolyte layers and having integrated into the probe body a gas measurement chamber which is connected to the measurement gas via a diffusion hole. The diffusion hole has a depth that extends beyond the gas measurement chamber into a solid electrolyte layer adjoining the gas measurement chamber. The manufacture of the planar electrochemical probe includes making the diffusion hole in the probe body after the electrolyte layers have been laminated together and before the layers are sintered.

    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 method for manufacturing a layer system, in particular for a sensor element for determining a physical variable of a gas to be measured, preferably for determining the concentration of a gas component or the temperature in an exhaust gas of an internal combustion engine. The layer system is composed of a ceramic carrier and at least one functional layer to which a solvent is added. A barrier layer is deposited on the ceramic carrier and the functional layer is deposited on the barrier layer. The barrier layer prevents the solvent from penetrating the ceramic carrier from the functional layer.
