Description
ченности создают в магнитоиндукдионном преобразователе 2 пр мые и обратные скачки Баркгаузена.In a magnetically inductive converter, 2 Barkhausen forward and reverse jumps are created.
Поток скачков Баркгаузена усиливаетс усилителем 3 и через амплитудный селектор, отсекающий тепловые шумы, поступает на ком1У1утатор 5, пропускающий только те импульсы, пол рность которых соответствует знаку управл ющего напр жени , поступающего на коммутатор 5 от генератора 1 через фазовращатель 8 и усилительограничитель 7. Угол поворота фазы устанавливают на фазовращателе 8 дл каждого типа ферромагнитного материала . С выхода коммутатора 5 на оконечный блок 6 поступают только скачки Баркгаузена, соответствующие обратным скачкам намагниченности, несущим информацию о фазовой структуре ферромагнитных материалов.The Barkhausen bursts flow is amplified by amplifier 3 and through an amplitude selector that cuts off thermal noise, enters the controller 5, transmitting only those pulses whose polarity corresponds to the sign of the control voltage supplied to the switch 5 from generator 1 through the phase shifter 8 and the amplifier limiter 7. Angle phase rotation is set on a phase shifter 8 for each type of ferromagnetic material. From the output of the switch 5 to the terminal block 6, only Barkhausen jumps arrive, corresponding to inverse jumps of magnetization carrying information about the phase structure of ferromagnetic materials.
