摘要： A sensor element is provided for determining at least one physical property of a gas mixture in at least one gas chamber, which includes at least one component to be identified, especially oxygen, and at least one oxidizable component, especially a combustion gas. The sensor element has at least one first electrode, at least one second electrode, and at least one solid electrolyte connecting the at least one first electrode and the at least one second electrode. The at least one second electrode has a lower catalytic activity, particularly a lower electrocatalytic activity with respect to the at least one oxidizable component than the at least one first electrode.

摘要： The invention relates to a gas sensor for determining the oxygen concentration in a gas mixture, especially in the exhaust gas of internal combustion engines. Said gas sensor comprises a pump cell having an outer pump electrode, exposed to the gas mixture, and an inner pump electrode, exposed to the gas mixture via a diffusion barrier, and a solid electrolyte body interposed between the outer pump electrode and the inner pump electrode. The gas sensor also has a reference electrode, exposed to a reference gas, and a sensor heating device. The outer pump electrode is connected to a circuit arrangement via a pump current line, the inner pump electrode via a measuring line, the reference electrode via a reference current line and the sensor heating device via two heating lines. The invention is characterized in that the pump current line and one heating line are electrically interconnected and grounded, the pump current can be supplied via the measuring line and the Nernst voltage can be tapped between the measuring line and the reference pump current line and the reference pump current flows from the reference electrode to the outer pump electrode.

摘要： A method for determining a temperature of a measurement sensor for determining an oxygen concentration in gas mixtures. In particular, the measurement sensor may be used in exhaust gases of internal combustion engines. A detection voltage which corresponds to the oxygen concentration and is provided by a Nernst measuring cell is evaluated, and the measurement sensor is regulated to an operating temperature using a heating device. The internal resistance of the Nernst measuring cell is determined in a first temperature range and is used to infer the temperature of the Nernst measuring cell, and the internal resistance of the heating device is determined in a second temperature range and is used to infer the temperature of the Nernst measuring cell.
