Sensor for resistive determination of concentrations of conductive particles in the case of gas mixtures

摘要

The invention relates to a sensor for resistive determination of concentrations of conductive particles in the case of gas mixtures, comprising a surface is exposed to the gas mixture with at least two electrodes, at a distance from one another are arranged on the surface, in such a way that the distance between the electrodes by means of which is located on the surface of the sensor is conductive particles from the gas mixture and can be bridged in this way, a conductive connection between the electrodes of the sensor can be produced, from which a measured variable for the concentration of the conductive particles in the gas mixture can be derived. The sensor is characterized in that at least in the region between the electrodes, a material is arranged, which is selected in such a manner that it has conductive sections, which in the case of addition of conductive particles from the gas mixture the formation of a conductive connection between the electrodes promote (fig. 2a).
