摘要： A method for operating a sensor element, in particular a lambda sensor, for determining the concentration of a gas component of a gas mixture, in which the gas component is removed from a measuring gas chamber by applying a pump voltage and the concentration of the gas component in the gas mixture is inferred therefrom. Oscillations of the pump current caused by dynamic pressure variations are taken into consideration for a correction of the sensor signal in that a frequency analysis of the pump current is carried out.

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.

摘要： A gas sensor for detecting particles in a gas stream has a first electrochemical pump cell, which has a measuring chamber in which a first electrode is disposed to pump particles between the first measuring chamber and the gas stream. Furthermore, a second electrochemical pump cell is provided, which has a second measuring chamber in which a second electrode is disposed so as to pump particles. The second measuring chamber is connected to the gas stream via an absorber medium for absorption of the particles to be detected. This makes it possible to absorb the particles to be detected in a first operating mode using the absorber medium, and to desorb the absorbed particles in a second operating mode, and to detect the quantity of the desorbed particles. Thus, the gas sensor is able to take even low concentrations into account, and short-term measuring errors do not have such a serious effect.

摘要： In a procedure to recognize the gas composition of a gas mixture, which consists of at least two gases of preferably different diffusion properties, delivered to a wideband lambda sensor, especially a gas mixture of an exhaust gas of an internal combustion engine of a motor vehicle, whereby the lambda sensor has a pumping cell with at least one gas measurement chamber, provision is made for the recognition of the gas composition of the gas mixture to result by means of modulation of the gas in the gas measurement chamber. Preferably the air number in the gas measurement chamber of the pumping cell is periodically altered, whereby the sensitivity of the lambda sensor to the gases, of which there are at least two, likewise periodically changes.
