DEVICE AND METHOD FOR MEASURING THE UNWINDED OR WINLED LENGTH OF ELECTRICAL WIRE OR CABLE OF AT LEAST ONE COIL

Abstract

This device (10) for measuring the unwound or wound length of an electrical wire or cable (12) comprises: a housing (14) having at least one guide opening (16) adapted to allow the wire or cable to pass through; two rollers (18, 19), arranged in the guide opening (16), which are rotatable, the wire or cable (12) being adapted to pass between them; a magnet, contained within one of the rollers (18, 19) and adapted to create a magnetic field whose value depends on the speed and direction of rotation of the roller containing the magnet; a magnetic field sensor, adapted to determine the position of the roller containing the magnet; a processor, adapted to determine the rotational speed of the roller containing the magnet and to deduce from this whether the wire or cable (12) is unwound or wound and the length unwound or wound.
