The results of the analytical review of well-known methods and technical means of nondestructive testing (NDT) of steel wire ropes are given. The operational capabilities and features of the functioning of this NDT equipment are considered. The results of the analysis showed that it is necessary to develop new approaches in the field of creating measuring sensors for the systems of technical control and diagnostics of steel ropes. The possibility of creating a new type of "hybrid" NDT method with extended functionality is substantiated on the basis of the ferrosonde. Unlike the traditional ferroprobe method, which uses the modulating action of an alternating magnetic field, the source of which is a multi-turn coil (magnetic dipole), the developed "hybrid" method is based on the use of a vibrator antenna (electric dipole) as a modulator, which initiates magnetoelectric processes in a ferromagnetic medium. In the proposed new method of NDT and its schematic implementation, several physical effects are used simultaneously: the effect of the defect on the character of the spatial distribution of the magnetic flux in the medium; the influence of the defect on the value of the transformer electromotive force; the influence of the defect on the magnitude of the magnetomodulation electromotive force. In fact, the proposed NDT method combines the features of three magnetic NDT methods: a constant magnetic field, an alternating magnetic field, and a ferro-probe method. Application of the proposed algorithmic processing of the measurement results of the output signal of the induction sensor makes it possible to identify the type of defect and to determine its geometric and physicochemical characteristics.
