In order to let users have a more in-depth understanding of the Ultrasonic transducer, the basic principle of its work and the various application areas are described in detail as follows.

First, the basic principles of Ultrasonic transducer

In the Ultrasonic transducer, the piezoelectric effect of the piezoelectric ceramic plate, which resonates at the same frequency between the two, is used to convert electrical energy into mechanical vibration. In general, ultrasonic waves are generated by ultrasonic generators, which are Ultrasonic transducer into mechanical vibrations, which are then guided by ultrasonic waves to form ultrasonic waves by equipment and ultrasonic receivers. As an energy converter, therefore, the Ultrasonic transducer is used to convert input electrical power into mechanical power (that is, ultrasonic) and transmit it back, at a very small fraction of the power itself.

The structure of the Ultrasonic transducer mainly consists of the shell, sound window, piezoelectric ceramic disc transducer, backing, lead-out cable, receiver, etc. . Among them, the piezoelectric ceramic plate transducer has the same function as most of the transducers, and is mainly used for transmitting and receiving ultrasonic waves, it is made up of leading-out cables, transducers, metal rings and rubber washers, and receives Dopler dial-back signals generated outside the frequency band of the piezoelectric ceramic disc transducer.

The use of Ultrasonic transducer

The Ultrasonic transducer are widely used and can be classified into industrial production, modern agriculture, road transport, medical equipment and military defence according to the industry in which they are used, can be divided into ultrasonic processing, ultrasonic cleaning, ultrasonic detection, detection, monitoring, telemetry, remote control, according to the division of the workplace, can be divided into liquid, gas, biological, etc.  According to the characteristics of the division, can be divided into power ultrasound, detection ultrasound, ultrasound imaging.
