Abstract

In a method and device for sensing changes in the filtering effect of electrostatic filtering devices (2) for separation of contaminants from gaseous streams, changes in voltage between filtering means (5) of the filtering device (2) are sensed, and signals are emitted (at 8) when a certain change in voltage takes place. The resonance voltage from filter cells (5) of the filtering device (2) are applied to a plurality of comparators (Figure 3) (not shown) set at different threshold levels. The outputs of the comparators control a pulse circuit which feeds means for emitting light, sound and control signals in dependance on changes in voltage between two filter cells (5). <IMAGE>
