AVS 700 HP-HT Acoustic velocity measurement system

ASTM D2845

The AVS 700 system is designed to conduct measurements of compressional and shear wave velocities in rock specimens while replicating in situ conditions, including overburden pressure, pore pressure, and temperature. The system consists of a pressure vessel that encases the rock sample, flanked by two compression platens housing piezo-electric crystals for both compression and shear wave measurements, a fluid vessel containing pore fluid for injection into the specimen, an air-operated pump responsible for controlling both confining and pore pressure, a fast-acting pulser-receiver and a data acquisition computer station. The pulser-receiver is responsible for exciting the ultrasonic sensors and displaying the resulting waveform signals. The rapid-response pulser is employed to initiate the 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.
