Abstract

A circuit and principle of operation of the instrument for measuring ultrasonic-wave propagation times, which is based on the autocirculation method using up-to-date electronics, are described. The circuit solutions, allowing one to sufficiently decrease the measurement error, are presented. The methods that ensure a high determination accuracy of ultrasonic-wave velocities in steel samples are considered. Areas of instrument applications are shown.
