Description
разовател к изделию. Дл этой цели служит привод 8, который устанавливаетс на контролируемое изделие и во врем контрол обеспечивает поступательное непрерывное движение вихретокового преобразовател 2 по нормали к поверхности контролируемого издели от максимального первоначального значени зазора до его минимального значени . При этом напр жение на выходе амплитудного детектора 6 постепенно растет, достига максимума (при частоте сигнала генератора 1 большей, чем частота настройки резонансного контура 3 при максимальном значении зазора).the developer to the product. For this purpose, serves drive 8, which is mounted on the test article and during the test ensures the forward continuous movement of the eddy current transducer 2 along the normal to the surface of the test article from the maximum initial gap value to its minimum value. At the same time, the voltage at the output of the amplitude detector 6 gradually increases, reaching a maximum (when the frequency of the generator 1 signal is greater than the frequency of tuning the resonant circuit 3 at the maximum gap value).
Цифровой индикатор 7 фиксирует максимальное значение сигнала, по которому суд т о результатах контрол .Digital indicator 7 records the maximum value of the signal by which the control results are judged.
В области максимального значени сигнала изменение зазора практически не сказываетс на точности контрол издели по вносимому комплексному сопротивлению вIn the area of the maximum signal value, the change in the gap has almost no effect on the accuracy of control of the product according to the impedance introduced into the
резонасныи контур при взаимодействии преобразовател с этим изделием.resonant circuit when the converter interacts with this product.
