According To:
Technique Regulation Of Concrete Defect Detection With Ultrasonic CECS21: 2000
Depth Measurement Principle
When Vibration Energy Transmits Through The Concrete And Passes The Crack, The Vibrate Energy Will Be Diffracted At The Point Of The Crack, Whose Diffraction Angle Has Geometrical Relationship With The Crack Depth. DJCS-05 Crack Depth Measurement Instrument Adopts This Geometrical Between The Diffraction Angle And Depth To Realize High Precision Depth Measurement.
