Способ вихретокового контроля, основанный на использовании вихретокового преобразователя в виде параллельного колебательного контура, который устанавливают в зоне контроля и подключают к источнику постоянного стабильного тока, измеряют падение напряжения на активном сопротивлении катушки вихретокового преобразователя, после чего отключают его от источника постоянного стабильного тока для формирования в вихретоковом преобразователе собственных затухающих колебаний, величина затухания которых является информативным параметром, по которому судят об изменениях физико-механических свойств контролируемого объекта, отличающийся тем, что выделяют один из периодов затухающих колебаний, измеряют его амплитуду и положение на временной оси относительно начала затухающих колебаний, после чего осуществляют принудительное гашение затухающих колебаний, при этом информативным параметром является изменение амплитуды периода и изменение положения периода на временной оси, а величину падения напряжения на катушке вихретокового преобразователя используют для автоматической регулировки усиления выходного сигнала.The eddy current control method based on the use of an eddy current transducer in the form of a parallel oscillatory circuit, which is installed in the control zone and connected to a constant current source, measures the voltage drop across the active resistance of the eddy current transducer coil, and then disconnects it from the constant current source to form eddy current transducer of its own damped oscillations, the attenuation of which is an informative parameter, which is judged on the changes in the physicomechanical properties of the controlled object, characterized in that one of the periods of damped oscillations is distinguished, its amplitude and position on the time axis are measured relative to the beginning of the damped oscillations, after which the damped oscillations are forcedly damped, while the informative parameter is the change the amplitude of the period and the change in the position of the period on the time axis, and the magnitude of the voltage drop across the coil of the eddy current transducer is used to automatically Oh adjust the output gain.
