    摘要： A gas sensor, comprises a substrate, a sensor unit including a functional layer and an electrode structure, and an electric heating and/or temperature measuring arrangement. An electrically conductive shielding structure is provided between the sensor unit and the electric heating arrangement in order to shield the measurement process at the sensor unit from interferences owing to the heating process, thereby reducing or preventing the effects of electrical fields caused by voltages applied to the heating arrangement from altering or disrupting the measurement process.

    摘要： An exhaust gas sensor is proposed for detecting a gas component in the exhaust gas of an internal combustion engine, having a control and evaluation unit and a sensor unit with an electrode structure with a first terminal and a second terminal, and a method for operating an exhaust gas sensor to determine the concentration of a gas component in the exhaust gas of an internal combustion engine is also proposed. The control and evaluation unit applies a bias voltage to the first terminal and/or the second terminal of the electrode structure, it being possible for the level of the bias voltage to be set in dependence on a characteristic of the sensor and/or in dependence on a loading of the sensor. A bias voltage is applied to the first terminal and/or to the second terminal of the electrode structure, with the level of the bias voltage being set in dependence on a characteristic of the sensor and/or in dependence on a loading of the sensor.

    摘要： A device determined the state of a soot particle filter of an internal combustion engine. An electrical measuring arrangement is embodied as a soot sensor for measuring a soot deposit and comprises an electrical component with a conductor structure for exciting an electrical or magnetic field which can be influenced by the soot deposit and characterizes an electrical or magnetic characteristic variable of the component. A measuring arrangement measures the electrical or magnetic characteristic variable of the component as a measure of the soot deposit. The conductor structure is arranged so that a partial volume region of the soot particle filter is penetrated by the electrical field, and the partial volume region forms part of the component.

    摘要： A method for producing a sensor (1) for detecting at least one gas constituent in the exhaust gas of an internal-combustion engine. An electrode structure (3), acting as a capacitor, is applied to a substrate (2). A gas-permeable zeolite layer (6) is applied to the electrode structure (3) and the substrate (2). After the application of the zeolite layer (6), the sensor (1) is heated in the presence of water vapor. During the heating, a voltage is applied to the electrode structure (3). A bias voltage, superimposed on the operating voltage of the electrode structure 3, is applied to a first connection 4 and/or to a second connection 5 of the electrode structure 3.
