Ultrasound technology is one of the general technologies based on physics, electronics, mechanics and materials science. Ultrasonic technology is accomplished through the physical process of ultrasonic generation, propagation and reception. Ultrasonic waves have characteristics such as focusing, directional, reflection, and transmission. According to the different sizes of ultrasonic vibration radiation, it can be roughly divided into:

Power applications that use ultrasonic waves to change objects or physical properties are called power ultrasound. For example, when enough energy is generated in a liquid to produce cavitation, it can be used Used for cleaning and emulsifying.

Using ultrasonic waves to obtain some information and obtain communication applications is called ultrasonic detection. For example, using the pulse reflection of ultrasonic waves in the medium to test the thickness of an object is called ultrasonic thickness measurement. Ultrasonic cleaning and application: Ultrasonic thickness measurement and application in the industrial field. Ultrasonic thickness measurement is a mature high-tech. Its biggest advantage is that the detection is safe, reliable and highly accurate, and it can patrol during operation for detection.

Ultrasonic thickness gauges are divided according to their working principles: vibration method, interference method and pulse reflection method. There are several types. Since the pulse reflection method does not involve the vibration mechanism and is not closely related to the smoothness of the surface of the object to be measured, the ultrasonic pulse thickness gauge is the most popular instrument among users. ?
