Description
Изобретение относитс к магнитным измерени м и преднаэиачено дл контрол магнитных свойств образцов разомкнутой формы.This invention relates to magnetic measurements and is designed to control the magnetic properties of open-ended samples.
Известно устройство, содержащее магнитопровод и исследуемый образец, на которые навиты соответственно компенсационна и намагничивак ца обмотки , подключенные к источнику питани , потенциалометр, полюса которого соприкасаютс с образцом вблизи его. концов, в зазоре потенциалометра нахо.цитс преобразователь Холла, соединенный с милливольтметром, служащим дл указани момента компенсации, когда разность магнитных потенциалов на концах образца равна нулю. Напр женность магнитного пол определ етс по значению тока намагничивани 13.It is known a device comprising a magnetic core and a test sample, to which, respectively, a compensation winding and a magnetizing winding are connected, connected to a power source, a potentiometer, the poles of which are in contact with the sample near it. All in all, a Hall transducer connected to a millivoltmeter serves to indicate the moment of compensation when the difference in magnetic potentials at the ends of the sample is zero, in the potential meter gap. The intensity of the magnetic field is determined by the value of the magnetizing current 13.
Недостатком данного устройства вл етс низка точность измерени напр женности магнитного пол , привод ща к большой погрешности при определении магнитных параметров образца .The disadvantage of this device is the low accuracy of the measurement of the magnetic field strength, which leads to a large error in determining the magnetic parameters of the sample.
Известно устройство дл контрол магнитных свойств сердечников разомкнутой , содержащее магнитопровод , потенциалометр, источник токаA device for monitoring the magnetic properties of open-core cores, containing a magnetic core, a potential meter, a current source, is known.
фазовращатель, делитель напр жени , усилитель тока и обмотки: намагничивающую , компенсационную и измерительную . Принцип действи прибора основан на компенсации магнитного потока в ферромагнитном сердечнике потенциалометра , обусловленного магнитным напр жением на контролируемом участке образца r2J,phase shifter, voltage divider, current amplifier and windings: magnetizing, compensating and measuring. The principle of operation of the device is based on the compensation of the magnetic flux in the ferromagnetic core of the potentiometer, due to the magnetic voltage in a controlled area of the r2J sample,

Недостатком данного устройства вл етс низка точность измерени , вызванна наличием зазора между образцом и магнитопроводом.The disadvantage of this device is the low measurement accuracy caused by the presence of a gap between the sample and the magnetic core.
Целью изобретени вл етс пов.ыше15 ние точности измерени путем исключени вли ни зазора на измер емую величину.The aim of the invention is to increase the measurement accuracy by eliminating the influence of the gap on the measured value.
Эта цель достигаетс тем, что в устройство дл измерени магнитных This goal is achieved by the fact that in a device for measuring magnetic
