FIELD: measurement equipment.
SUBSTANCE: acoustic-emission signal is recorded in an impregnation autoclave, at the same time the envelope of the recorded signal is extracted in the real time mode, the envelope is assessed by the threshold value, the form of acoustic emission pulses is selected in order to eliminate influence of gas bubbles aggregated in an impregnation solution and their collapse.
EFFECT: improved validity of measurements of controlled processes.
