Application of ultrasonic sensors


Ultrasonic sensors are sensors developed using the characteristics of ultrasound. Ultrasound is a mechanical wave with a higher vibration frequency than sound waves. It is generated by the vibration of the transducer wafer under the excitation of voltage. It has high frequency, short wavelength, small diffraction phenomenon, especially good directivity, which can be directed into rays. Dissemination and other characteristics.


Principle of Ultrasonic Ranging Sensor:

   Ultrasound has a great ability to penetrate liquids and solids, especially in solids that are opaque to sunlight. It can penetrate to a depth of tens of meters. When the ultrasonic wave hits the impurity or the interface, it will produce a significant reflection to form an echo, and it can produce a Doppler effect when it hits a moving object. Therefore, ultrasonic testing is widely used in industry, national defense, biomedicine and other aspects. Ultrasound is used as a detection method, and ultrasonic waves must be generated and received. The device that accomplishes this function is an ultrasonic sensor, which is habitually called an ultrasonic transducer or an ultrasonic probe.
