Beschreibung
Zusammenfassung:	The invention relates to a particle sensor unit (10) having a measuring chamber (12) and a control unit (14), wherein at least one electrode pair having two electrodes (22, 24) is arranged in the measuring chamber (12), and wherein the control unit (14) has a high-voltage source (26) which is connected to the electrodes (22, 24) and which generates an electrical voltage prevailing between the two electrodes (22, 24), and wherein the control unit (14) has a current measuring device (36), which measures an electric current flowing between the two electrodes (22, 24) and carried by charged particles (23) or dendrites (34) made of particles (23). The particle sensor unit is characterized in that at least one of the two electrodes (22, 24) has a heating element (28, 30), which is thermally coupled to one of the two electrodes (22, 24) and is controlled by the control unit (14).
