Astm E2491 Phased Array Assessment Block Ndt Calibration Blocks

PAUT-ASTM E2491 Phased Array Assessment Block 304 Stainless Steel (Inch Version) Geometry:Four (4) angled holes (30A , 45A , 60A and 75A ) at 1/16" (.0625) diameter Array of 18 holes on 1" radius at .040" diameter. Angular separation between holes is 5.0A , with 2.5A of separation between the last two holes in the array. Array of 18 holes on 2" radius at 5/64" (.0781) diameter. Angular separation between holes is 5.0A , with 2.5A of separation between the last two holes in the array. Vertical column of 16 holes at .040" diameter with .120" of separation between holes. Angled row of 12 holes at 1/16" (.0625) diameter with .200" of separation between holes. Machine engraved tick mark at radii centerline. Dimensions: 1" thick x 4" wide x 6" long. ASTM E2491 Phased Array Assessment Block is a general purpose Phased Array calibration block used for beam characterization and evaluation of system performance characteristics. Use it as a baseline block to determine long-term instrument performance changes, generate DAC curves and evaluate linear / angular resolution, focusing ability and beam steering capabilities. With a variety of targets, this small, lightweight block is also perfect for customer demonstrations of phased array ultrasonics capabilities.
