Use of Ultrasonic Thickness Gauge and its indication

【Abstract】Ultrasonic Thickness Gauge is a commonly used measuring instrument. It is of great significance to understand its principle and use it correctly for the accuracy of measurement results. According to the working principle and function of the ultrasonic Thickness Gauge, the article summarizes the different measurement methods and the problems that are easy to occur in the measurement and their solutions.

【Key words】ultrasonic Thickness Gauge; measurement method; correct use; influence

The ultrasonic Thickness Gauge measures the thickness according to the principle of ultrasonic pulse reflection. When the ultrasonic pulse emitted by the probe passes through the object to be measured and reaches the interface of the material, the pulse is reflected back to the probe, which is determined by accurately measuring the propagation time of the ultrasonic wave in the material. The thickness of the material to be measured. All kinds of materials that can make ultrasonic waves propagate inside them at a constant speed can be measured by this principle. The Thickness Gauge designed according to this principle can accurately measure various plates and various processed parts, and can also monitor various pipelines and pressure vessels in production equipment, and monitor their thinning degree after being corroded during use , Can be widely used in petroleum, chemical industry, metallurgy, shipbuilding, aviation, aerospace and other fields.
