CVA-100 Circumferential Velocity Anisotropy Apparatus


The GCTS CVA-100 Circumferential Velocity Anisotropy Apparatus is used to determine the compression P-wave velocities and shear S-wave velocities in rock core specimens in different orientations with great accuracy.

 

  • Measurement f P-wave and S-wave velocities with the included transducers.
  • Map of P-wave and S-wave velocities vs. orientation angle and height.
  • Includes turntable with vernier scale for precise measurement of angular orientation of the specimen.
  • Pneumatic actuators for automatic clamping of sensors onto specimen.
  • 200 kHz of 1 MHz frequency crystals, other frequencies available upon request
  • 100 mm (4 inch) maximum specimen diameter.
  • Very easy to set up and use.
  • Requires GCTS ULT-100 or any other suitable ultrasonic measurement device.

The GCTS CVA-100 Circumferential Velocity Anisotropy Apparatus is used to determine the compression P-wave velocities and shear S-wave velocities in rock core specimens in different orientations.

 

This apparatus, when used with a GCTS ULT-100 or other suitable ultrasonic measurement device, can obtain the velocity versus angle and height data with relative ease and precision.

Standard apparatus includes:

  • P-wave and S-wave ultrasonic velocity transducers (source and receiver), which come in standard frequencies of 200 kHz or 1 MHz
  • High quality anodized aluminum construction of the base, columns and the supporting jig for the ultrasonic transducers
  • Pneumatic actuators with return toggle switch for quick and accurate transducers positioning on the sample. Includes air lines and quick-connect fittings for compressed air input
  • Turntable with precise vernier scale and fasteners for samples with up to 100 mm diameter
  • 40 cm (H) x 32 cm (W) x 30 cm (L). 20 kg mass.

NOTE: Pneumatic actuators require compressed air input.
