При наличии внешнего магнитного пол с составл ющей в плоскости сердечника 1, в нем происходит модул ци магнитного нотока за счет изменский мапштной нроницаемости материала, котора оказываетс различной по величине и фазе в двух любых диаметрально противоположных участках Кольцевого сердечника 1. Благодар этому две части модулированиого магнитного потока в сердечнике 1 также различаютс по величине и в .измерительной обмотке 2 наводитс суммарный сигнал удвоенной частоты. Этот сигнал, проход через полосовой фильтр 3, приобретает близкую к синусоидальной форму и поступает на прибор 4, на другой вход которого подано опорное напр жение основной частоты.If there is an external magnetic field with a component in the plane of the core 1, it modulates the magnetic current due to the change in material permeability of the material, which is different in size and phase in any two diametrically opposite parts of the Ring core 1. Due to this, two parts of the magnetic modulation the flux in core 1 also varies in magnitude and a total double frequency signal is induced in the measuring winding 2. This signal, the passage through the band-pass filter 3, acquires a close to sinusoidal shape and is fed to the device 4, to the other input of which the reference voltage of the fundamental frequency is applied.
По амплитуде сигЕала с -измерительной обмотки 2 суд т о величине составл ющей исследуемого магнитного лол в плоскости сердечника 1, а по фазе относительно опорногоAccording to the amplitude of the signal from the measuring winding 2, the magnitude of the component of the magnetic lol under investigation in the plane of the core 1 is judged, and in phase relative to the reference
