AVS-A Atmospheric acoustic velocity system

ASTM D2845


The computer-controlled acoustic velocity measurement system facilitates the controlled propagation of both compressional (P) and shear waves (S or S1&S2) through geological rock specimens. Its integrated hardware and software employ state-of-the-art technology, enabling highly accurate determination of compression and shear wave velocities as well as dynamic elastic constants. This comprehensive system is equipped with essential components, including a swift-loading sample holder, a switch box, and a high-speed pulser-receiver that administers excitation to the ultrasonic sensors and visually presents the resultant waveform signals. The rapid-response pulser is employed to initiate excitation of the ultrasonic sensor, while an exceptionally high-speed analog-to-digital converter is utilized for the rapid capture and storage of the ensuing waveform signals. This setup ensures precise data acquisition and analysis for advanced research and geological investigations.
