【 摘 要 】

A superminiature eddy current probe of a transformer type designed for the study of ferromagnetic materials is developed. The developed probe operates under the control of software and hardware complex, providing a signal to the exciting coil and receiving a signal from the measuring coil. The system is designed for automatic movement of the probe at a given speed over the object of control. The data of steel-dielectric-steel object scanning are presented. Measurements were carried out linearly and discretely. The data of the influence of the gap between the measuring coil of the eddy current probe and the object of control are also presented.
