摘要： A method is described for controlling the soot deposition on sensors. A sensor element is provided, which includes a first electrode and a second electrode. Different measuring voltages U1 and U2 can be applied to the sensor element. During a first time period t1, the sensor element is operated at a higher voltage U1 until a triggering threshold AP of the sensor element is exceeded, while it is operated at a voltage U2, which is different from higher voltage U1, U2 being lower than voltage U1, during a second time period t2.

摘要： A sensor element is provided for gas sensors, in particular to determine particles in gas mixtures, the sensor element including at least one electrochemical measuring element exposed to the gas mixture to be determined, and at least one temperature-measuring element integrated into the sensor element. The temperature-measuring element includes a resistor track, which has an electric resistance of less than 180 Ohm at 0° C. The resistor track may thus be produced by thin-foil technology, such as screen printing, for example.

摘要： The invention concerns a procedure to ascertain a concentration of sooty particles in an exhaust gas system of an internal combustion engine or a depletion of an emission control system of the internal combustion engine due to the loading of sooty particles, whereby the sooty particle concentration in the exhaust gas system is determined by means of a collecting particle sensor, which emits a sensor signal and whereby the depletion of the emission control system due to the loading of sooty particles is determined from the sooty particle concentration.The task is thereby solved, in that the sensor signal is corrected by means of predetermined corrections with regard to a sensor temperature and/or an exhaust gas temperature and/or a flow velocity of the exhaust gas and/or a voltage applied at the particle sensor. Transverse sensibilities of the particle sensor can thereby be taken into account during the evaluation; and the determination of the accumulated loading of sooty particles and the determination of the sooty particle concentration in the exhaust gas system are improved. In the process, the sensor temperature enters into the correction to the extent that a temperature dependence of the electrical resistance of the loading of sooty particles is determined in a preparation phase and can be taken into account during the evaluation of the sensor signal.

摘要： A sensor for determining the concentration of particles in gases, in particular of soot particles, has at least one substrate element, and a measuring area between at least one first and one second measuring electrode, the two measuring electrodes being configured so that by applying a voltage between the measuring electrodes, an asymmetric electric field is formed on the measuring area. The sides of the first and second measuring electrodes, facing one another, may not be parallel to one another, for example. Furthermore, at least one measuring electrode may have a structure along the side facing the other measuring electrode or along the finger electrodes.
