Abstract
The invention relates to an electrostatic projector (P) comprising: an insulation body (); a rotatably movable projection member (); rotational driving means (); high-voltage power supply means (); conducting elements (); a detection device () for evaluating the rotation speed of the projection member (), the detection device () including at least one target () on a rotary component and a sensor () adapted for detecting the or each target. The projector (P) further includes at least one insulating wall () that defines a housing () surrounding the sensor () for insulating the entire sensor () from the conducting elements (). The sensor () is separated from the space (V) scanned by the rotating target () by an essentially axial detection distance (H).
