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 inside 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.
|
|
|
|
To
make sure the probe working properly, it needs to use couplant
to isolate the air between the probe surface
|
|
and the
measured workpiece surface. The liquid used for the coupling between the
probe and workpiece is
|
|
called as couplant.
