Ultrasonic Thickness Gauge Principle
Nov 13, 2018

Ultrasonic thickness gauge principle

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

This instrument 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 extent of corrosion after corrosion. Can be widely used in petroleum, chemical, metallurgy, shipbuilding, aviation, aerospace and other fields.

Let's take a look at the following small series, the principle of ultrasonic thickness gauge

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.
