Abstract

A method of wear detection of a coated belt or rope includes measuring an initial electrical resistance of one or more cords strands or wires of the coated belt or rope. The initial electrical resistance is calibrated by repeating the measuring of initial electrical resistance and populating a database with the measured initial electrical resistance values. A true initial resistance is determined from the population of initial electrical resistances and subsequent measured values of electrical resistance of the one or more cords strands or wires of the coated belt or rope.
