Description
(54) МАГНИТО.ЛЕТР ДЛЯ ИЗМЕРЕНИЯ НАПРЯЖЕННОСТИ ПЕРЕМЕННЫХ МАГНИТНЫХ ПОЛЕЙ(54) MAGNETO. FLIGHT FOR MEASURING THE TENSION OF VARIABLE MAGNETIC FIELDS
тока и размещенный в эталонном магнитном поле обмотки 5 индуктивности, помещают в измер емое неременное магнитное поле. Под воздействием эталонного и измер емого магнитных полей сопротивление датчика 4 измен етс , а на нем по вл етс изменение падени напр жени , которое раздел етс фил.арами 7 и 9.current and placed in the reference magnetic field of the winding 5 of the inductance, is placed in a measurable non-reusable magnetic field. Under the influence of the reference and measurable magnetic fields, the resistance of the sensor 4 changes, and a change in the voltage drop appears on it, which is separated by files 7 and 9.
Сигнал измер емого магнитного пол регистрируетс индикатором 10. Составл юща падени напр жени , определ ема эталонным магнитным полем на выходе датчика 4 поступает через фильтр 7 и вьшр митель 8, где сопоставл етс с калибровочным током, на регулируемый вход стабилизатора 2 посто нного тока.The signal of the measured magnetic field is recorded by the indicator 10. The component voltage drop, determined by the reference magnetic field at the output of the sensor 4, is supplied through filter 7 and the expander 8, where it is compared with the calibration current, to the adjustable input of the stabilizer 2 of direct current.
При равенстве коэффициента передачи устройства номинальному значеьшю сигнал рассогласовани отсутствует и ток через датчик не мен етс . Из-за температурной или временной нестабильности параметров датчика выходной сигнал отклон етс от своего номинального значени , на выходе выпр мител 8 по вл етс сигнал рассогласовани и ток мен етс , что измен ет его чувствительность и приводит к восстановлению номинального значени коэффициента передачи устройства.If the device transmission coefficient is equal to the nominal value of the error signal, there is no and the current through the sensor does not change. Due to the temperature or temporal instability of the sensor parameters, the output signal deviates from its nominal value, at the output of rectifier 8 a mismatch signal appears and the current changes, which changes its sensitivity and leads to the restoration of the nominal value of the transmission coefficient of the device.
