Ultrasonic thickness gauge is based on the principle of ultrasonic pulse reflection for thickness measurement. When the ultrasonic pulse emitted by the probe reaches the material interface through the measured object, the pulse is reflected back to the probe. Measure the thickness of the material. This principle can be used to measure all kinds of materials that can make ultrasonic waves propagate inside them at a constant speed.
This thickness gauge adopts the pulse reflection ultrasonic measurement principle, which is suitable for the measurement of the thickness of various materials whose ultrasonic can propagate at a constant speed and can be reflected from its back. This instrument can accurately measure various plates and various processed parts. It can be widely used in various fields such as petroleum, chemical industry, metallurgy, shipbuilding, aviation and aerospace.

The thickness measurement of this ultrasonic thickness gauge is that the ultrasonic pulse generated by the probe passes through the couplant to reach the object under test. Part of the ultrasonic signal is reflected by the bottom surface of the object. The probe receives the echo reflected by the bottom surface of the object, and accurately calculates the ultrasonic wave. Round trip time, and calculate the thickness value by the following formula, and then display the calculation result.
