FIELD: measuring technology.
SUBSTANCE: invention relates to the field of measuring technology and serves for non-destructive testing of breaks in external and internal strands in multistrand ropes and extended laminated structures. The effect is achieved by the proposed eddy current transducer for non-destructive testing of strand ropes, consisting of at least one feed-through exciting inductor, at least two differentially connected feed-through inductors designed to detect local defects, and at least one measuring feed-through inductance coil, designed to measure the change in the cross-section of the rope, in which the dimensions of the coils and the distance between them are specially selected.
EFFECT: increasing the signal/noise ratio by narrowing the control zone, leveling the sensitivity threshold to defects in the outer and inner layers of strand ropes.
