摘要： In an apparatus that ascertains a concentration of a component in a gas mixture, the apparatus includes: a gas measurement chamber, in which the concentration of the component is adjustable against an influence of an interface, acting across a diffusion barrier, with the concentration in the gas mixture, whereby the influence of the interface is compensated for by a controllable current of ions of the component by way of a solid electrolyte, which is charged with a controllable pumping voltage, serves as a pumping mechanism, and is located between the gas measurement chamber and the gas mixture, so that a parameter that characterizes a current constitutes a measurement for the concentration in the gas mixture, whereby the solid electrolyte is at least periodically charged with a specified constant pumping voltage as a function of at least one state parameter of the gas mixture.

摘要： A sensor element is used to detect a physical property of a measuring gas, preferably to determine the oxygen content or the temperature of an exhaust gas of an internal combustion engine. The sensor element contains a first solid electrolyte layer and a second solid electrolyte layer. A first printed conductor and a second printed conductor are provided on opposite sides of the first solid electrolyte layer, the first printed conductor including a first electrode and a feed line to the first electrode, and the second printed conductor including a second electrode and a feed line to the second electrode. A third printed conductor, which includes a third electrode and a feed line to the third electrode, is provided on the second solid electrolyte layer. The second printed conductor is positioned between the third electrode and the first printed conductor.
