Description
(5) УСТРОЙСТВО ДЛЯ КОНТРОЛЯ ПАРАМЕТРОВ ФЕРРОМАГНИТНЫХ МАТЕРИАЛОВ(5) DEVICE FOR CONTROL OF PARAMETERS OF FERROMAGNETIC MATERIALS
1one
Изобретение относитс к измерительной технике и может быть использовано при неразрушающем контроле параметров ферромагнитных материалов и изделий из них.The invention relates to a measuring technique and can be used in the non-destructive testing of parameters of ferromagnetic materials and products from them.
Известно устройство дл контрол качества материалов, содержащее электромагнитный преобразователь, усилитель , блок сравнени и индикатор. Работа устройства заключаетс в том, что выдел ют сигнал скачков Баркгаузена , среднюю мощность которого сравнивают с мощностью того же сигнала от образца с известными свойствами l.A device for controlling the quality of materials is known, comprising an electromagnetic transducer, an amplifier, a comparison unit and an indicator. The operation of the device consists in extracting the Barkhausen jump signal, the average power of which is compared with the power of the same signal from the sample with known properties l.
Недостаток известного устройства низка точность контрол .A disadvantage of the known device is low control accuracy.
Наиболее близким к предлагаемому по технической сущности вл етс устройство дл контрол параметров ферромагнитных материалов, содержащее источник перемагничивани и последовательно соединенные электромагнитной преобразователь, усилитель, измеритель дисперсии магнитного шума и индикатор J.Closest to the proposed technical entity is a device for monitoring the parameters of ferromagnetic materials, containing a source of magnetization reversal and a series-connected electromagnetic transducer, amplifier, magnetic noise dispersion meter and indicator J.
Недостатком известного устройства вл етс низка точность контрол , . обусловленна вли нием дисперсии теплового шума, особенно при малых уровн х выходного сигнала и при колебани х температуры окружающей среды.A disadvantage of the known device is the low control accuracy,. caused by the influence of the dispersion of thermal noise, especially at small output signal levels and when the ambient temperature fluctuates.
Цель изобретени - повышение точности контрол .The purpose of the invention is to improve the accuracy of control.
