    摘要： An arrangement and method for determining a characteristic variable of a fluid having a movably suspended measuring element, a restraining element, an advancing element and a control device. The control device is designed to actuate the restraining element and/or the advancing element in order to move the measuring element between the first measuring point and the second measuring point, to determine a time period which the measuring element requires in order to be moved between the first measuring point and the second measuring point, and to determine a characteristic variable of the fluid on the basis of the determined time period, a predetermined force and a known geometry.

    摘要： A method for operating a soot sensor that has an interdigital electrode structure, to which a measurement voltage is applied. Soot particles from an exhaust gas flow are deposited onto the interdigital electrode structure and the measurement current is evaluated as a measure of the soot load of the soot sensor. The interdigital electrode structure is burned clean at or above a predetermined soot load, which is detected by means of an upper current threshold. The method includes burning the interdigital electrode structure clean by heating up the soot sensor after the upper current threshold has been reached; monitoring the measurement current while the interdigital electrode structure is being burned clean; and stopping the burning clean when the value of the measurement current has reached a lower current threshold.

    摘要： A particle sensor arranged in an exhaust duct such that particles from the exhaust-gas flow accumulate on and/or between at least two sensor electrodes when a voltage greater than a limit voltage is applied between the two sensor electrodes and substantially no particles accumulate if the voltage is lower than the limit voltage. During a first time period, a first voltage greater than the limit voltage is applied between the sensor electrodes. During a second time period, a second voltage, lower than the limit voltage, is applied between the sensor electrodes, and/or the particle sensor is heated to a predefined temperature, such that substantially no particles accumulate on and/or between the at least two sensor electrodes. Following the second time period, a third voltage greater than the limit voltage is applied between the sensor electrodes.

The soot sensor is electrically connected to an evaluation circuit with is permanently installed in the motor vehicle. In order to specify a method for performing functional diagnostics on a soot sensor and/or for detecting further components in the soot, with which method it is possible to detect a faulty soot sensor and/or further components in the soot in a cost-effective way, the evaluation circuit measures the temperature coefficient of the soot sensor and detects the defectiveness of the soot sensor and/or the presence of further components in the soot on the basis of the temperature coefficient of the soot sensor.
