  • Method for operating a sensor for recording particles in a gas stream and device for implementing the method
    Patent number: 7587925
    Abstract: A method for operating a sensor for recording particles in an exhaust gas flow and a device for carrying out the method are provided, in which at least one measure of the exhaust gas flow is ascertained and in which the measure of the exhaust gas flow is taken into consideration in the valuation of the particle sensor signal made available by the particle sensor. The procedure is based on the knowledge that the exhaust gas flow, for instance, the exhaust gas volume flow, has an influence on the particle sensor signal made available by the particle sensor, especially when the measuring effect is based on the depositing of particles on a sensor surface. Using the procedure, a possibly present cross sensitivity of the particle sensor with respect to different exhaust gas flows is taken into consideration, so that the measuring accuracy is increased.

  • Sensor for detecting particles in a gas stream and method for its manufacture
    Patent number: 7574895
    Abstract: A soot particle sensor for an exhaust system of an internal combustion engine includes a first electrode device and a second electrode device. The electrode devices are situated at a distance from one another and are able to be exposed to the gas stream, at least in some areas. It is provided that the electrode devices are separated from each other by an intermediate layer made of an electrically insulating material, and the electrode devices have free edges that are set apart from each other by the thickness of the intermediate layer and are able to be exposed to the gas stream.
