1.3 Measuring Principle

The digital ultrasonic thickness gauge determines the thickness of a part or structure

by accurately measuring the time required for a short ultrasonic pulse generated by a

transducer to travel through the thickness of the material, reflect from the back or in-

side surface, and be returned to the transducer. The measured two-way transit time

is divided by two to account for the down-and-back travel path, and then multiplied by

the velocity of sound in the material. The result is expressed in the well-known

relationship:

Where： H－Thickness of the test piece.

v－Sound Velocity in the material.

t－The measured round-trip transit time.
