Abstract (en)

[origin: WO2007023035A1] The invention relates to an electrostatic particle sensor for sensing particles (P) in aerosols, particularly soot particles in exhaust gases. Said electrostatic particle sensor comprises a covered electrode (M) which has an effective flow volume (V) and is penetrated by a gas flow to be tested, an inner electrode (I) located inside the covered electrode, and a voltage source (U) that is in electrically conducting connection to both electrodes (M, I). The invention is characterized in that a potential which depends on the throughput (D) through the volume (V) per time unit (t) is impressed upon the voltage source (U).
