摘要：
The invention relates to a device (100) for operating a particle sensor which comprises at least one high-voltage electrode (102) and at least one ground electrode (104). The device (100) has a processor (106), a measuring device (108), and a voltage supply unit (110), and an electric field (E) can be generated between the at least one high-voltage electrode (102) and the at least one ground electrode (104). The measuring device (108) is designed to measure a charge compensation current (I) which flows to the at least one high-voltage electrode (102) and/or the at least one ground electrode (104) while an exhaust gas flow flows at least partly in a region of the electric field (E) between the at least one high-voltage electrode (102) and the at least one ground electrode (104). The processor (106) is designed to actuate the voltage supply unit (110) in order to generate the electric field (E) by means of an alternating voltage (U) between the at least one high-voltage electrode (102) and the at least one grou
