Ultrasonic sensors are ubiquitous in modern life. They can be seen everywhere. Ultrasonic sensors use the principle of ultrasound to emit sound waves higher than 20KHz. The emission direction is horizontal and vertical. A medium such as B-ultrasound is used for diagnosis; it is also a form of energy. When its intensity exceeds a certain value, it can affect the change by destroying the state, nature, and The structure is used as a treatment.
The human ear can hear the sound from 20Hz-20KHz, the ultrasonic wave is greater than 20KHz, so the human ear cannot hear, even if working for a long time will not affect the human hearing, energy concentration, horizontal and vertical forward sound waves. It does not produce contaminated objects during work and cannot cause any pollution to the environment. The general protection level is above IP65. It can effectively propagate in gas, liquid, solid, solid melt and other media. It can penetrate the container to measure the liquid in the container without contacting the liquid to be measured. With this, it can also measure corrosive liquids.
The domestic application of ultrasound is in the early 1950s, nearly 30 years later than abroad. With the development of reform and opening up, the application of ultrasonic sensors has also become wider. So far, ultrasonic sensors have been widely used in ultrasound. Inspection, ultrasonic treatment, ultrasonic cleaning, ultrasonic degreasing, ultrasonic medical treatment, ultrasonic cosmetic, ultrasonic pharmaceutical, ultrasonic welding, ultrasonic measurement and other scenarios. According to these scenarios, the industries are medical industry, semiconductor industry, optical industry, petrochemical industry, Electronics industry, mechanical and electrical industry, pharmaceutical industry, textile industry, surface treatment industry, railway repair field, military equipment field, electroplating and painting process application, photosensitive material manufacturing, beverage industry, food industry, paper industry, jewelry industry, glasses Fields, dishwashing industry, plastic welding, metal welding, beauty and weight loss.
The use of ultrasonic sensors is not limited to this. It also promotes the aging of wine. A bottle of wine from the last century is very expensive. It can not be bought without tens of thousands of dollars. The aging wine uses chemical precipitation to produce chemical changes. Using an ultrasonic sensor with a super frequency of 17.5-22KHz for 5-10 minutes can shorten the alcoholation time of the wine by one-third to one-half.
