METHOD AND APPARATUS FOR NONDESTRUCTIVE INSPECTION OF ROPES MADE FROM FERROMAGNETIC STEEL WIRE

摘要

FIELD: physics.;SUBSTANCE: magnetic field parameters are measured in at least three independently lying points in the interpolar space. At the first point, the magnetic field parameter value serves to obtain information on the cross-sectional area on the metal and local defects, and at the other two points, the magnetic field parameter value serves to obtain information on the strand pitch and the coordinate along the axis of the inspected rope.;EFFECT: high sensitivity of the measuring unit, the signal-to-noise ratio and high reliability of detecting local defects.;6 cl, 3 dwg
