Abstract
Изобретение относитс к области магнитных измерений и может быть использовано дл записи начальной кри- вой намагничивани и петли гистерезиса ферромагнитных материалов. Целью изобретени вл етс повышение точности за счет непосвепственного определени напр жени внутреннего магнитного пол в образце ферромагнитного материала. Устройство содержит источник тока с соленоидом 2, измерительную катушку 3, усилитель 4, интегратор 5, двухкоординатный регистратор 6, датчик 7 Холла, запитывае- мьм от источника 8 посто нного тока и закрепленный на штоке вибратора 9, на вход которого подаетс сигнал с выхода задающего генератора 10, а также синхронньй детектор в виде фазовращател 11, усилител 12, ключа 14 и фильтра 15. Сигнал на вход син- .хронного детектора поступает с выхода усилител 13. Устройство включает также усилитель 16, фильтр 17 нижних частот и сумматор 18. 2 ил. i (Л с:The invention relates to the field of magnetic measurements and can be used to record the initial magnetization curve and the hysteresis loop of ferromagnetic materials. The aim of the invention is to improve the accuracy due to the incompetent determination of the voltage of the internal magnetic field in a sample of ferromagnetic material. The device contains a current source with a solenoid 2, a measuring coil 3, an amplifier 4, an integrator 5, a two-coordinate recorder 6, a Hall sensor 7 fed from a DC source 8 and attached to the rod of the vibrator 9, to the input of which a signal is output from the driver generator 10, as well as a synchronous detector in the form of a phase shifter 11, amplifier 12, key 14 and filter 15. The signal to the input of the synchronic detector comes from the output of amplifier 13. The device also includes an amplifier 16, a low-pass filter 17 and an adder 18. 2 silt i (Л с:
