Description
Предлагаемое устрой.ство отличаетс от известных тем, что в нем, с целью повышени чувствительности, применена обратна св зь, а в качестве органа обратной св зи применен датчик Холла, что обеспечивает уменьшение погрешностей, вызванных, например, колебани х напр жени питани .The proposed device differs from the known ones in that, in order to increase the sensitivity, feedback is applied, and the Hall sensor is used as a feedback element, which reduces the errors caused by, for example, voltage fluctuations in the supply voltage.
На чертеже показана схема устройства.The drawing shows a diagram of the device.
Чувствительный элемент схемы - термометр сопротивлени / измен ет при колебани х температуры баланс моста, образованного сопротивлени ми 2, S и 4. Е диагональ моста включен показываюш;ий прибор 5, в разрывы ветви линии которого включен датчик э.д.с. Холла 6, расположенный в поле электромагнита 7, усилитель S и фазочувствительный выпр митель 9. Таким образом, з силитель и фазочувствительный выпр митель оказываютс охваченными обратной св зью. Св зь датчика Холла с источником питани через электромагнитную систему обеспечивает нечувствительность схемы к колебани м напр л ени питани .The sensing element of the circuit - a resistance thermometer / changes when the temperature fluctuates, the balance of the bridge formed by the resistances 2, S and 4. The diagonal of the bridge is turned on, and the device 5 has an emf sensor in its line breaks. Hall 6, located in the field of the electromagnet 7, the amplifier S and the phase sensitive rectifier 9. Thus, the silyn and phase sensitive rectifier are covered by feedback. The connection of the Hall sensor with the power supply through an electromagnetic system ensures the insensitivity of the circuit to fluctuations in the supply voltage.
