Description
рез резистор .3 и элекпронйый ключ 4 поступает на бло-к 5 емкостей. В свою очередь, электронный клЮЧ 4 улра(Вл етс гедерато|ро .м / пр моугольных импульсов. При этом происходит подавление аддитивной пом-ехи, вследствие чего форма сигнала после .резистора 5 будет ир .моуголь-ной, а его амплитудное аначен е характе1ризует различие в свойствах эталонного и испытуемого образцов . Это напр жение затем уснливаетс усилителем 6 и фикси|руетс регистратором 7.A cut resistor .3 and an electronic switch 4 are fed to a block of 5 capacitors. In turn, the electronic key 4 ulra (the influence of the gederate | ro. M / rectangular impulses. In this case, the additive suppression occurs, as a result of which the waveform after the resistor 5 will be irregular and its amplitude It characterizes the difference in properties of the reference and test specimens.This voltage is then compounded by amplifier 6 and fixed by the recorder 7.
В результате преобразовани формы выходного сигнала дифферввциальио включбвных измер.ительных .катушек существенно .повышаетс чувствительность и разрешаЮ (Ш,а способность, что особенно важио при неразруша1ош,ем контроле микротреш ,ин, термообработки, твердости глубнны упроч енного сло , где различие электромагнитных свойств контролируемого и исходного образцов незначительно.As a result of the conversion of the output waveform of differential camouflage measurements of coils, sensitivity and resolution are significantly increased (W, and the ability, which is especially important for non-destructive testing of microcracks, heat treatment, hardness, depth of the hardened layer, where the difference in electromagnetic properties and initial samples slightly.
