Abstract

Изобретение относитс  к измерительной технике, именно к контролю изделий при их теплоакустических испып тани х по сигналам акустической эмиссии . Цель изобретени  -повышение точности за счет одновременности получени  результатов измерени . Измерительный мост 1 переменного тока питаетс  высокочастотным генератором 3, а в одно из плеч моста 1 -включен преобразователь 2, устанавливаемый на изделии 8. Сигнал информации снимают с другой диагонали моста и раздел ют его по частоте. Высокочастотна  составл юща  несет информацию о температуре издели , а низкочастотна  составл юща  - информацию об акустических колебани х. 7 ил.The invention relates to a measurement technique, namely, to the control of products in their heat-acoustic tests by acoustic emission signals. The purpose of the invention is to improve the accuracy due to the simultaneity of obtaining measurement results. The measuring bridge 1 of the alternating current is powered by a high-frequency generator 3, and one of the arms of bridge 1 includes a converter 2 mounted on product 8. The information signal is removed from the other diagonal of the bridge and divided by frequency. The high frequency component carries information about the temperature of the product, and the low frequency component contains information about acoustic oscillations. 7 il.
