What is Ultrasonic Thickness Gauge?
Ultrasonic thickness gauge is a high-precision thickness gauge that utilizes the principle of ultrasonic measurement and adopts a high-speed processor and high-integrated chip design to achieve portable, non-destructive, fast and accurate measurement of thickness and sound velocity of various materials. The ultrasonic thickness gauge is suitable for measuring the thickness of various materials, such as steel, various metals, glass, ABS, plastic, PVC, and ductile iron, that can use ultrasonic waves to propagate inside it at a constant speed and can be reflected from the back.
The ultrasonic thickness gauge is mainly composed of the host and the probe. The host circuit includes three parts: the transmitting circuit, the receiving circuit, and the counting display circuit. The high-voltage shock wave generated by the transmitting circuit excites the probe to generate ultrasonic transmitting pulse waves. After the pulse wave is reflected by the medium interface, it is received by the receiving circuit. After being counted by the single-chip microcomputer, the thickness value is displayed on the liquid crystal display. It is mainly based on the propagation speed of the sound wave in the sample multiplied by half of the time passing through the sample to obtain the thickness of the sample.
How does an ultrasonic thickness gauge work?
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, and the thickness of the material to be measured is determined by accurately measuring the propagation time of the ultrasonic wave in 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.
Application of Ultrasonic Thickness Gauge
Ultrasonic thickness gauges are mainly used to detect hard materials (steel plates, glass), however, if they are soft materials (such as sofas, or sponges), they cannot be measured, and the speed of sound of the measured materials should be paid attention to when detecting materials. The speed of sound used is different for different materials. Handheld ultrasonic thickness gauges can accurately measure various plates and various processed parts, and can also monitor various pipes and pressure vessels in production equipment to monitor their thinning degrees after being corroded during use. Ultrasonic thickness gauges for sale on ATO.com can be widely used in petroleum, metallurgy, chemical industry, shipbuilding, aviation and other fields.
