Description
Предлагаемый способ увеличени чувствительности магнитометров основан на том при1щипе, что посто нную составл ющую преобразованного тока от изменени магнитного пол подвод т к чувствительному элементу, реагирующему иа изменение магнитного пол такой пол рности , чтобы вс кое изменение тока вызывало изменение магнитного пол .The proposed method for increasing the sensitivity of magnetometers is based on the principle that the constant component of the converted current from a change in the magnetic field is applied to a sensitive element that reacts to a change in the magnetic field of such polarity that the current change causes a change in the magnetic field.
На схематическом черт-еже изображено устройство, позвол ющее осуществить предлагаемый споспб увеличени чувствительности магнитометров .The schematic diagram shows a device that allows the proposed method to increase the sensitivity of magnetometers.
Ток от ге-нератора / поступает к чувствительному элементу 2, реагирующему на магнитное поле через элемент 3, который св зывает со схемой чувствительный элемент 2, представл ющий собой катушку индуктивности , содержащую пермал-ЛОЙ .The current from the generator / goes to the sensitive element 2, which reacts to a magnetic field through the element 3, which connects the sensitive element 2 to the circuit, which is an inductance coil containing permal-LOY.
Получаемое в индикаторной схеме и индикаторе 5 в результате приращени магнитного пол приращение посто нного тока подводитс через усилитель 4 к обмотке индуктивности чувствительного элемента 2 (или к специальной обмотке) такой пол рности , чтобы вс кое изменение тока от изменени пол вызывало увеличение первичного пол .The increment of direct current obtained in the indicator circuit and indicator 5 as a result of the magnetic field increment is supplied through the amplifier 4 to the inductance winding of the sensitive element 2 (or to the special winding) of such polarity that the current change from the field change causes an increase in the primary field.
Така схема позвол ет получить усиление первичного пол , а следовательно , и увеличение чувствительности магнитометра.Such a scheme allows the gain of the primary field, and hence an increase in the sensitivity of the magnetometer.
