ABSTRACT:
A device for determining the position of a scraper which is displaceable for the transport of coating material in a supply path of thereof, the coating material comprises a sensor responding to the presence of the scraper. This sensor is accommodated in a separate measuring head, which contains an inner, self-sufficient current source and a circuit arrangement which generates an electric output signal indicating presence or absence of the scraper on the sensor. The information in this output signal is conducted by means of a device, which manages without galvanic connection, preferably via an optical waveguide, to an evaluation circuit, electrically insulated at a distance from the measuring head and which generates an electric output signal used for controlling other parts of the plant. A device of this kind can also be used for detecting scrapers where, as frequently in electrostatically operating coating plants, the sensor has to be attached at a point located at high electric potential.
