<p>Method for measuring the content of particles in gas, for example the concentration of carbon black in exhaust gas from internal combustion engines and the like, wherein in order to simplify the measuring process and improve the accuracy of the measurements, there are used two electrodes arranged on an insulating support at a certain interval as a detector of the precipitation of particles deposited. The conductivity of the leakage current surface between the electrodes is measured and the particle content may be determined therefrom. It is possible to detect a conductivity change by measuring the current for the firing voltage in a klydonograph. </p> |
