Abstract: The invention relates to a method and apparatus for measuring lay length of a wire rope having a number or external strands to form a rope having spiral grooves in the surface between the strands. A magnetic flux circuit is generated, part of which is formed within a region of the advancing wire rope.

Linking the oscillating pattern to distance along the rope reveals the lay length, which corresponds to a number of oscillations which is the same as the number of strands at the surface.
