Ultrasonic Thickness Measurement Principle and Unique Functions
Ultrasonic thickness measurement principle
Ultrasonic thickness gauge is based on the principle of ultrasonic pulse reflection to measure the thickness of the measured material. When the ultrasonic pulse generated by the probe reaches the material interface through the measured object, the pulse is reflected back to the probe, and the thickness of the measured material is determined by accurately measuring the time of ultrasonic wave propagation in the material. This principle can be used to measure various materials that can allow ultrasonic waves to propagate inside them at a constant speed.
The main advantages of ultrasonic thickness gauge
When the workpiece to be measured cannot be measured by conventional measurement methods, ultrasonic thickness gauges can be used for measurement. The main advantage of ultrasonic thickness measurement is that it can be used to measure the thickness of closed containers and other complex samples that are difficult or impossible to reach both sides of the material, because it only needs to touch one side of the material to measure the thickness. Thickness gauge is generally handheld, simple and convenient to use, and have a wide measurement range.. Ultrasonic thickness gauge can quickly and accurately measure the thickness of the material, which is an essential testing instrument in the non-destructive testing industry.
Application of ultrasonic thickness gauge
Ultrasonic thickness gauge adopts the pulse reflection ultrasonic measurement principle, which is suitable for measuring the thickness of various materials in which ultrasonic waves can propagate at a constant speed inside and be reflected from the back. This instrument can accurately measure various plates and various processed parts. It is used for the wall thickness of various plates, pipes, boiler vessel wall thickness and local corrosion and rust, and It can be widely used in product inspection in petroleum, chemical industry, metallurgy, shipbuilding, aviation, aerospace and other fields, and plays a major role in the safe operation and modern management of in-service equipment.
The special function of ultrasonic thickness gauge
A. The measurement range is wide
The measurement range of ultrasonic thickness gauge is very wide, YUSHI PM-5 series thickness gauge can match different frequencies and different types of single crystal probes, can complete most of the measurements, and ensure the accuracy of measurement.
B. With single point measurement function
Single point measurement is measured at any point of the measured material with a probe, and the displayed value is the thickness value. Especially in the case that only one side can be touched, it can better show its superiority.
C. Material sound velocity can be measured with a known thickness
Ultrasonic thickness measurements will only be accurate if the material’s sound velocity is consistent with the instrument’s calibrated sound velocity. To ensure that the ultrasonic thickness gauge can get better measurement values during use, the sound velocity can be measured by the known thickness.
About YUSHI INSTRUMENTS
YUSHI UM-2 ultrasonic thickness gauge can meet most ordinary measurement requirement, UM-2 is an easy-to-operate thickness gauge, operators can complete the most commonly used thickness measurement applications after basic learning.
For applications that the basic thickness gauge cannot measure, YUSHI UM-5 series thickness gauge and PM-5 series thickness with waveform adjustment can solve more difficult measurement problem. With the unique A-scan interface of the UM-5 and PM-5 series, users can directly see the color ultrasonic signal waveform on the screen. By adjusting the waveform, any echo can be locked, so as to completing the measurement of most difficult parts.
