Summary: | A method for determining soot in exhaust gases of burners or internal combustion engines with the aid of a sensor element which includes at least two measuring electrodes exposed to the exhaust gas and one heating element, a voltage being applied to the at least two measuring electrodes during a measuring phase and the current flow or electrical resistance occurring between the measuring electrodes being determined and output as a measure for the particle concentration or the particle mass flow, characterized in that during the measuring phase, the temperature of the sensor element is monitored and the sensor element is heated by the heating element, if the temperature of the sensor element falls below a limiting temperature. |
