Abstract (en)

[origin: WO2009010471A1] The invention relates to a sensor for detecting the size distribution of particles in a gas stream. Said sensor comprises an electrode system having at least three electrodes (1, 1'; 2, 2'; 3, 3'; 4, 4') lying in a plane, at least one voltage supply device (201; 202; 203; 204) and at least one voltage measuring and/or current measuring device (301; 302; 303; 304). The sensor is characterized in that two electrodes each of different polarity (1, 1'; 2, 2'; 3, 3'; 4, 4') form a pair of electrodes (11; 12; 13; 14), said pair of electrodes (11; 12; 13; 14) being arranged along an imaginary beam (X1, S1), lying in the plane of the electrodes, in such a manner that the beam (X1, S1) extends between the two electrodes (1, 1'; 2, 2'; 3, 3'; 4, 4') of a pair of electrodes (11; 12; 13; 14). The pairs of electrodes (11; 12; 13; 14) arranged along the beam (X1; S1) are connected to at least one voltage measuring and/or current measuring device (301; 302; 303; 304) in such a manner that the voltage and/or the current flowing between every pair of electrodes (11; 12; 13; 14) can be determined individually. The invention also relates to a corresponding method and to the use thereof.
