conserve battery's life
Optional software to transfer the memory data to
PC
- Optional thermal mini- printer to print the
measured data via RS-232 port.

1.3 Measuring principle

The digital ultrasonic thickness gauge determines the
thickness of a part or a structure by accurately measuring
The time required for a short ultrasonic pulse generated by
a transducer to travel through the thickness of the material,
to reflect from the back or inside surface and be returned
to the transducer. The measured two-way transit time is
devided 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 following relationship:
v
=
H
Where: H ---- thickness of the test piece
v ---- sound velocity in the material
t ---- the measured round-trip transit time
