摘要： A sensor for determining gas components and/or gas concentrations in gag mixtures, in particular, in the exhaust gas of an internal combustion engine, includes an inner pump electrode, an inner pump electrode supply conductor, a measuring electrode and a measuring electrode supply conductor. The inner electrode and the measuring electrode are in contact with the measuring area. In addition, separation is maintained between the measuring electrode supply conductor and the inner pump electrode supply conductor at least in the hot area of the sensor. At least in the hot area at least one of the electrode supply conductors is in contact with at least one oxygen reservoir, there being an at least largely gas-tight barrier between this and the measuring area. Furthermore, a sensor may include an inner pump electrode and an outer pump electrode, an inner pump electrode supply conductor and an outer pump electrode supply conductor, separation being maintained between them by a solid electrolyte foil, the outer pump electrode supply conductor being in contact at least in some areas with an oxygen reservoir. The design features of the two sensors may also be implemented in one sensor.

摘要： In a method for testing a measuring sensor for the determination of an oxygen concentration in a gas mixture, the measuring sensor supplies a detection voltage furnished by a Nernst measuring cell and corresponding to the oxygen concentration. The detection voltage is evaluated by a circuit arrangement and is picked off between a first electrode exposed to the gas mixture and a second electrode exposed to a reference gas. The measuring sensor is heated to operating temperature. The Nernst measuring cell is exposed to a constant test voltage and a gas mixture with a well-defined oxygen concentration and a measuring current of the Nernst measuring cell is evaluated.

摘要： Disclosed is a gas sensor, particularly a lambda probe, for determining the oxygen concentration in the exhaust gas of an internal combustion engine that is operated using a fuel-air mixture. Said gas sensor comprises a pump cell with an outer electrode that is exposed to the exhaust gas, an inner electrode located in a measuring chamber which is separated from the exhaust gas by means of a first diffusion barrier, and an electronic circuit for generating a voltage applied between the outer electrode and the inner electrode as well as for measuring and evaluating a pump current that is generated in said process in order to draw a conclusion therefrom about the composition of the fuel-air mixture. The inventive gas sensor is characterized in that the outer electrode is arranged in an independent measuring volume which is separated by means of an additional, second diffusion barrier whose coefficient of diffusion is different from that of the first diffusion barrier while the circuit is configured so as to preferably repeatedly reverse the polarity of the voltage.

摘要： In a method for detecting a level of contamination of a particle sensor provided with two electrodes situated on an insulator material for generating an electrical field, the insulator material is heated to above a limiting temperature of the insulator material at which the insulator material begins to become conductive. The insulator material is modulated by heating or cooling, the modulation being carried out at a lower temperature and an upper temperature which are each above the limiting temperature. The variation over time of a measuring signal which may be picked up between electrodes is measured during the modulation. The measured variation over time of the measuring signal is compensated using a theoretical variation over time of the measuring signal in a contamination-free state of the particle sensor in order to obtain a variation over time of a differential signal.
