    摘要： A sensor for determining the concentration of a gas component in a gas mixture is provided, including at least one pump cell having an outer pump electrode which is exposed to the gas mixture and an inner pump electrode located in a measuring chamber, and further including a Nernst cell having a Nernst electrode located in the measuring chamber and a reference electrode located in a reference gas channel. The pump cell and the Nernst are formed in a composite structure of stacked solid electrolyte layers, which structure has an upper layer containing the pump electrodes, a middle layer containing the measuring chamber and the reference gas channel, as well as a lower layer containing a heating element and two supply leads. To suppress noise in the output signal of the sensor, the leads of the Nernst cell are disposed in one plane, in parallel side-by-side relationship, and symmetrically to at least one of the two supply leads of the heating element.

    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 for determining gas components and concentrations in a gas mixture that is particularly suitable for analyzing HC, NOx and CO in exhaust gases of internal combustion engines in the sensor, an outer electrode, that is separated from an MOx electrode by an electrolyte layer, is applied on a substrate. In this context, the outer electrode and the MOx electrode are in communication with the gas mixture to be analyzed. In addition, the outer electrode contains a region that is in contact with a gas-permeable tunnel layer which in turn contains a region that is directly exposed to the gas mixture to be analyzed, so that the gas to be analyzed can be supplied to the outer electrode via the gas-permeable tunnel layer.

    摘要： This invention provides a method for monitoring the function and/or regeneration of a gas probe. The invention includes a measurement of first and second pump currents of the gas probe and a determination of a difference between the first and second pump currents (&Dgr;I). If &Dgr;I exceeds a pregiven value, then a saturation pump voltage is applied and the difference between a resulting pump current and a previously stored minimum pump current (&Dgr;I plus) is determined. If &Dgr;I plus exceeds a pregiven value, then a regeneration voltage is applied.
