Abstract
Изобретение относитс к электромагнитным средствам контрол изделий и может быть использовано в неразрушающем контроле дл измерени параметров дефектов и усталостиы.х трещин. Цель изобретени - повыщение точности контрол за счет отстройки от мешающих параметров. Устройство содержит блок возбуждени , блок ви.хретокового преобразовател , блок обработки сигнала и индикации, блок автоматической настройки и соединенные в замкнутый контур магнитооптический преобразователь , фотоанализатор и блок подмагничивани . Выход фотоанализатора подключен к управл ющему входу блока автоматической настройки, дискретный выход которого подключен к управл ющему входу блока подмагничивани . I ил.The invention relates to electromagnetic means of testing products and can be used in non-destructive testing to measure the parameters of defects and fatigue of cracks. The purpose of the invention is to increase the accuracy of control due to detuning from interfering parameters. The device comprises an excitation unit, a terrestrial current converter unit, a signal processing and indication unit, an automatic adjustment unit and a closed-loop magneto-optical converter, a photo analyzer and a biasing unit. The output of the photo analyzer is connected to the control input of the automatic tuning unit, the discrete output of which is connected to the control input of the biasing unit. I il.
