Ultrasonic Thickness Tester TT-300
Ultrasonic Thickness Gauge measuring with
ultrasonic wave, is applicable for measuring the thickness of any
material in which ultrasonic wave can be transmitted and reflected
back from the other face.
The gauge can provide quick and accurate measurement to various
work pieces such as sheets of board and processing parts. Another
important application of the gauge is to monitor various pipes and
pressure vessels in production equipment, and monitor the thinning
degree during using. It can be widely used in petroleum, chemical,
metallurgy, shipping, aerospace, aviation and other fields.
The primary theory of measuring thickness with ultrasonic wave is
similar to that of measuring thickness with optical wave. The
ultrasonic wave emitted from the probe reaches the object and
transmits in it. When the ultrasonic wave reaches the bounding
surface of the material, it is reflected back to the probe. The
thickness of the material can be determined by accurately measuring
the time of the ultrasonic wave transmitting in it

- Cleaning surface Before measuring, please clean any
dust, dirt and rust on the object, and remove any cover such as
paint, etc. on it.
- Improving requirement on roughness Too rough surface
will cause error in measurement. Before measuring, please smooth
the surface of object by grinding, polishing or filing, etc. or
use coupling agent with high viscosity for that.
- Rough machined surface The regular fine slots on
rough machined (by such machines as lathe or planer) surface
will also cause error in measurement. The way for compensating
that is the same as that in 5.2. In addition, by so adjusting
the included angle between the probe's crosstalk interlayer
plate (the metallic layer passing through the center of probe
bottom) and the fine slots of the object that the interlayer
plate is perpendicular or parallel to the fine slots, and by
taking the min. value of the readouts as the measured thickness,
one can also get better results.
- Measuring cylindrical surface When measuring
cylindrical material, such as pipes, oil tubes, etc., it is very
important to select properly the included angle between the
probe's crosstalk interlayer plate and the axial line of the
material to be measured. Briefly to say, first couple the probe
with the material to be measured, make the probe's crosstalk
interlayer plate be perpendicular or parallel to the axial line
of the object, shake the probe vertically along the axial line
of the object, the readouts displayed on screen will change
regularly. Select the min. readout from displayed ones as the
accurate thickness of the object.
The standard for selecting the included angle between the
probe's crosstalk interlayer plate and the axial line of the
object is depending on the curvature of it. For a pipe with
large diameter, the probe's crosstalk interlayer plate should be
perpendicular to the axial line of the object; for a pipe with
small diameter, one can measure with the probe's crosstalk
interlayer plate being both parallel and perpendicular to the
axial line of the object, and take the min. readout as the
