Angle Beam Distance Calibration with Miniature Angle Beam Block
Angle Beam Distance Calibration (Miniature Angle Beam Block).
The following procedure works only for a 45o angle beam.
Position the search unit at P-1 and then P-2 as shown in Figure 1-21. Obtain peak signals from R-1
and then from R-2.
The angle beam metal travel at P-1 is 1.00 inch; at P-2, it is 2.00 inches. Use multiple back ref lections
to calibrate longer distances.
Ensure you are using the proper transducer and standard matched for the
material you wish to inspect.
EX: A = aluminum transducer
S = steel transducer
