Abstract
Способ вихретокового контроля, заключающийся в том, что в зоне контроля на заданном расстоянии от металлической поверхности объекта контроля устанавливают вихретоковый датчик, вихретоковый пробник с катушкой индуктивности которого закрепляют на подвижном штоке привода шагового двигателя, на катушку индуктивности вихретокового пробника подают переменный электрический сигнал, по величине амплитуды которого на этой катушке индуктивности измеряют величину зазора между металлической поверхностью объекта контроля и вихретоковым пробником с катушкой индуктивности и, на основе этого, определяют величину перемещения металлической поверхности объекта контроля вдоль направления на катушку индуктивности, отличающийся тем, что в вихретоковом датчике задается и поддерживается в процессе измерений диапазон разрешенных значений величины зазора между металлической поверхностью объекта контроля и вихретоковым пробником с катушкой индуктивности, при отклонении за пределы которого измеренного значения величины этого зазора выдается управляющий сигнал на шаговый двигатель для продольного перемещения подвижного штока привода этого двигателя на такое расстояние, чтобы устанавливаемое при этом значение величины зазора между металлической поверхностью объекта контроля и вихретоковым пробником с катушкой индуктивности попадало в середину диапазона величин его разрешенных значений.The method of eddy current testing, which consists in the fact that in the control zone at a given distance from the metal surface of the test object, an eddy current sensor is installed, the eddy current probe with an inductance coil of which is fixed on the movable rod of the stepper motor drive, an alternating electrical signal is applied to the inductance coil of the eddy current probe, in magnitude whose amplitudes on this inductance coil measure the size of the gap between the metal surface of the test object and the eddy current probe with an inductance coil and, on the basis of this, determine the amount of movement of the metal surface of the test object along the direction to the inductor coil, characterized in that in the eddy current sensor it is set and maintained in during measurements, the range of allowed values of the gap between the metal surface of the test object and the eddy current probe with an inductance coil, when the measured value of this gap deviates beyond which, a control signal is output to the stepper motor for longitudinal displacement of the movable rod of the drive of this motor to such a distance that the distance set at In this case, the value of the gap between the metal surface of the test object and the eddy current probe with an inductance coil fell into the middle of the range of its permitted values.
