Ultrasonic sensor applications
Nov 14, 2017

Ultrasound sensing technology used in different aspects of production practice, and medical applications is one of its most important applications, the following medical examples illustrate the application of ultrasonic sensing technology. Ultrasound in medicine is mainly used to diagnose diseases, which has become an indispensable diagnostic method in clinical medicine. The advantages of ultrasonic diagnosis: no pain on the subjects, no damage, the method is simple, clear imaging, diagnosis of high accuracy. So easy to promote, by medical workers and patients welcome. Ultrasound diagnosis can be based on different medical principles, we take a look at a representative of a so-called A-type method. This method is to use ultrasonic reflection. When ultrasound propagates in human tissue encountering two media interfaces with different acoustic impedances, a reflected echo is produced at that interface. Each time a reflective surface is encountered, the echo is displayed on the oscilloscope's screen, and the impedance difference between the two interfaces also determines the amplitude of the echo.

In industry, the typical application of ultrasonic is non-destructive testing of metal and ultrasonic thickness measurement of two. In the past, many technologies have been hampered by the inability to detect the interior of objects and the presence of ultrasonic sensing technology has changed this situation. Of course, more ultrasonic sensors are fixedly mounted on different devices to "quietly" detect what people want. In future applications, ultrasound will be combined with information technology and new material technologies, and more intelligent and highly sensitive ultrasonic sensors will emerge.
