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： An electrochemical measuring sensor having a solid electrolyte, a first electrode exposed to a gas to be measured and a second electrode exposed to a reference gas, with the electrodes preferably being arranged on opposite sides of the solid electrolyte. At least one of the electrodes (16, 20) is provided with a contouring (24) on its side (22) that is exposed to the gas to be measured or to the reference gas, with the contouring being a trench-shaped groove (26) embossed into the surface of the electrode such that the electrode is pressed into the adjacent solid electrolyte in the region of the groove. According to the method, the embossing is done while the electrode and the solid electrolyte are in the non-sintered state, and the sensor is subsequently sintered.

摘要： A planar polarographic sensor for determining the lambda value of gas mixtures, for use with exhaust gases in internal combustion engines, includes a planar ceramic carrier sheet having an outer pumping electrode and an inner pumping electrode respectively arranged on opposite planar sides thereof, and a diffusion barrier. The outer and inner pumping electrodes, and the diffusion barrier are arranged on the planar ceramic carrier sheet so that the measuring gas is fed via the diffusion barrier to the inner pumping electrode. The sensor has front and side edge faces. The diffusion barrier is configured as a diffusion layer at least partially covering the inner pumping electrode and exposed at least at one edge face of the sensor to the measuring gas. A diffusion-free planar region of the sensor is provided with an equalizing layer having the same thickness as the diffusion layer, and the equalizing layer is disposed in the same plane with and adjacent to the diffusion layer.
