Ultrasonic Wave Velocity Test System
The ultrasonic velocity measurement system is a non-destructive method of measuring compression and shear waves through rock samples as a function of temperature, confining and pore pressures.
This is a complete system and is comprised of all required electrical and mechanical hardware e.g. signal conditioner and pulse generator, ultrasonic velocity and data acquisition controller, ultrasonic platens including combined P and S (S1 & S2) transducers as well as the required software. This package conducts ultrasonic velocity measurement tests on rock samples. The test is applicable at temperatures of up to 150 °C and pressures of up to 210 MPa.
Based on the length of the sample and travel-time from transmitter to receiver, ultrasonic wave velocities (Vp & Vs) are calculated and can be used with a rock triaxial or rock polyaxial test system. This simultaneously measures and calculates the static and dynamic properties of rock e.g. shear modulus (G), Poisson’s ratio (u), bulk modulus (K) and Young’s modulus (E), as well as other parameters.
