摘要： The invention relates to a device for operating a particle sensor in the exhaust gas duct of an internal combustion engine, the particle sensor comprising an interdigital electrode for determining the particles contained in the exhaust gas and a heater for regenerating said particle sensor and an engine management system being associated with the internal combustion engine. Provision is thereby made for a probe control unit to be connected to said particle sensor, for the probe control unit to be disposed in a separate assembly between said particle sensor and the engine management system and for said probe control unit to be connected to said engine management system via a digital bus or an analog interface. The invention relates further to a corresponding method. Device and method allow for the autonomous operation of a particle sensor without the engine management system having to be configured for the operation of said particle sensor.

摘要： The invention relates to a method for the self-diagnosis of a particle sensor used for determining a particle content in a gaseous stream, wherein the particle sensor includes on its surface at least two interlocking, interdigital electrodes and a heating element separated from said electrodes by an insulation layer. Said particle sensor can be heated by said heating element in a regeneration phase, and a soot concentration can thereby be removed from the same. Provision is made according to the invention for a semiconductive layer to be formed in the insulation layer directly beneath the electrodes by means of external doping or auto-doping and in order to perform the self-diagnosis for a measurement voltage to be applied at least periodically between the electrodes and a self-diagnostic current to be measured. The invention furthermore relates to a device for the self-diagnosis of a corresponding particle sensor, said particle sensor being connected to an engine management system or a sensor control unit and said engine management system or said sensor control unit including apparatuses for diagnosing the soot concentration on the particle sensor and the particle sensor itself. Said engine management system or said sensor control unit includes according to the invention apparatuses for evaluating a self-diagnostic current when applying an AC or DC voltage as a measurement voltage to the electrodes. When using DC voltage as the measurement voltage, the particle sensor can furthermore be heated for a short time to temperatures >500 EC via said engine management system or said sensor control unit in order to perform the self-diagnosis. A self-diagnosis of the electrodes, which are provided for the particle measurement, can be carried out as a pre-delivery inspection by the manufacturer as well as in subsequent use with the presented diagnostic method and the corresponding device for carrying out this method. A preferred application of the method provides for its use within the scope of the on-board diagnosis of diesel internal combustion engines.

摘要： Self-diagnosis of a particle sensor may be used for determining a particle content in a gaseous stream. The particle sensor may include at least two interlocking, interdigital electrodes and a heating element. The heating element may be separated from the electrodes by an insulation layer. The particle sensor may be heated in a regeneration phase and a soot load on the particle sensor can thereby be removed. A semiconductive layer may be formed in the insulation layer directly beneath the electrodes by means of external doping or auto-doping. To perform a self-diagnosis, a measurement voltage may be applied at least periodically between the electrodes and a self-diagnostic current may be measured.

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.
