Description

буждени  датчика. Сигналы, наводимые в приемных катушках 7, 8 и 9 через коммутатор 10, попарно подаютс  через усилители И и 12, детекторы 13 и 14 к блок 15 отношени . Индикатор 16 с электронно-лучевой трубкой имеет два входа: вход X развертки и вход Y вертикального отклонени . На вход X подаетс  сигнал с формировател  3, на вход Y - с блока 15, благодар  чему обеспечиваетс  индикаци  относительного положени  дефекта по глубине контролируемой детали.sensor buzz The signals induced in the receiving coils 7, 8 and 9 through the switch 10 are fed in pairs through the amplifiers And and 12, the detectors 13 and 14 to the ratio block 15. The cathode ray tube indicator 16 has two inputs: a scan input X and a vertical deflection input Y. The input from X is fed from the imaging unit 3, to the input Y from block 15, thereby providing an indication of the relative position of the defect in the depth of the part being monitored.

Возбуждающа  6 и приемные катушки 7, 8 и 9 располагаютс  по контролируемой поверхности так, чтобы обеспечить достаточный уровень сигналов от локальных неоднородностей но всей площади поверхности издели . В зависимости от последней количество катушек может быть увеличено.Exciting 6 and receiving coils 7, 8 and 9 are located on the controlled surface so as to provide a sufficient level of signals from local inhomogeneities but the entire surface area of the product. Depending on the latter, the number of coils may be increased.
