Изобретение относитс к магнит- ным измерени м и может быть исполь зовано дл измерени напр женности магнитного пол в локальной области изделий из ферроМа.гнитных материалбб., а также дл определени физико-механических свойств изделий по значению тангенциальной составл ющей напр женности пол на их поверхностиThe invention relates to magnetic measurements and can be used to measure the magnetic field strength in the local area of products made of ferromagous material, as well as to determine the physical and mechanical properties of products based on the value of the tangential component of the field strength on their surface.
Известен способ измерени напр1 женности магнитного пол на поверхности образца с помощью размещенной на пластине пьезоэлектрического резонатора катушки, питаемой посто нным током, и совершающей колебани в магнитном поле, напр женность которого определ етс по изменению собственной частоты колебаний резонатора JA known method for measuring the intensity of a magnetic field on the surface of a sample using a coil fed by a piezoelectric resonator fed by a direct current and oscillating in a magnetic field, the strength of which is determined by the change in the natural frequency of the resonator J
Недостатком способа вл етс низка точность измерени .The disadvantage of this method is low measurement accuracy.
Известен способ определени напр женности магнитного пол в локальных област х образцов, в которомThere is a method for determining the intensity of the magnetic field in local regions of samples, in which
компенсируют тангенциальную составл к|щу1б напр женности магнитного пол магнитным полем обмотки потенциаломётра установленного на поверхности образца. Индикатором момента компенсации служат два датчика Xoллaf2J.compensate for the tangential strength of the magnetic field magnetic field by the magnetic field of the potential meter winding installed on the sample surface. Indicators of the moment of compensation are two sensors Holaf2J.
Недостатком известного способа в:л етс низка точность, так как размер локальной области, в которой производитс измерение напр женности , определ етс конечными размерами феррозонда-потенциалометра.The disadvantage of the known method is: low accuracy, since the size of the local area in which the intensity is measured is determined by the final size of the flux probe potential meter.
Цель - повышение точности.The goal is to increase accuracy.
