Phased Array Ultrasonic Calibration Blocks Type A & Type B
Standard Material: Carbon Steel
Optional Material: Stainless Steel, Aluminum Alloy
Phased Array “Type B” Calibration Block
ASTM E2491 Phased Array Assessment Block is a general-purpose
phased array calibration block used for beam characterization and
evaluation of system performance characteristics.
It serves as a baseline block to monitor long-term instrument
performance changes, generate DAC curves, and evaluate
linear/angular resolution, focusing ability and beam steering
capability.
Featuring a variety of targets, this compact, lightweight block is
also ideal for customer demonstrations of phased array ultrasonic
capabilities.
Phased Array “Type A” Calibration Block
This block is used during initial setup and calibration of phased
array ultrasonic units.
It can perform beam angle verification, wedge delay calibration,
sensitivity calibration, DAC/TCG generation, and other functions.
With dimensions similar to an IIW-Type block, it is specially
engineered for phased array applications.
The block includes:
- 4.000" and 2.000" radii
- 19 through holes of 0.040" diameter
- 1 through hole of 0.080" diameter
- 4 FBHs: 0.080" diameter × 0.080", 0.160", 0.235", 0.315" deep
- 4 FBHs: 0.157" diameter × 0.040", 0.120", 0.200", 0.275" deep
- 3 FBHs: 0.080" diameter × 0.120" deep machined into the 2.000"
radius
- 4 EDM notches: 0.004", 0.008", 0.012", 0.016" deep × 0.020" wide ×
1.00" long
