Measuring principle of ultrasonic thickness gauge

Let's take a look at the measurement principle of the ultrasonic thickness gauge.

Ultrasonic thickness gauges, based on the principle of ultrasonic measurement, are suitable for the measurement of the thickness of various materials that enable ultrasonic waves to propagate inside at a constant speed and which can be reflected from the back side.

Ultrasonic thickness gauges can accurately measure a variety of plates and various machined parts. Another important aspect is the ability to monitor various pipes and pressure vessels in production equipment to monitor their degree of corrosion after corrosion. . Can be widely used in petroleum, chemical, metallurgy, shipbuilding, aviation, aerospace and other fields.

The principle of ultrasonic thickness measurement is similar to the principle of light wave measurement. The ultrasonic pulse emitted by the probe reaches the object to be measured and propagates in the object. When it reaches the material interface, it is reflected back to the probe. The thickness of the material to be tested is determined by accurately measuring the time the ultrasonic wave propagates through the material.
