Applicable Materials
It is suitable for measuring the thickness of metals (such as steel, cast iron, aluminum, copper, etc.), plastics, ceramics, glass, resin, glass fiber and other good ultrasonic conductors.
Basic Principles
The principle of ultrasonic thickness measurement is similar to that of light wave measurement. The ultrasonic pulse emitted by the probe reaches the measured object and propagates in the object. When it reaches the material interface, it is reflected back to the probe. The thickness of the measured material is determined by accurately measuring the time of ultrasonic propagation in the material.
