A digital hypersonic method for quality inspection of piezoelectric crystals. The method is grounded on automatic metering of a time interval between echo pulses and Supersonic Wave Attenuation (SWA) in an inspected article with information output in a digital form. The hardware and functional features of hypersonic system is presented. The method can be used in factory and scientific laboratories to obtain express-information on quality of ingoing materials for fabricated items. ER -
