UT Sound Beam Profile Using IOW Block 20dB Drop

This video demonstrates how to plot your ultrasonic transducer sound beam profile using the IOW Beam Calibration Block. This technique plots the vertical beam profile of your transducer using 8 different depth side drilled holes using the 20dB signal drop. Plots were made using the same transducer with 45, 60 and 70 degree screw on wedges.
Equipment: Olympus EPOCH 1000i UT tester, GE 2.25MHZ, 0.5" diameter transducer, 45, 60 and 70 degree screw on wedges and the IOW beam calibration block.
