Ultrasonic transducer: A device that converts high-frequency electrical energy into mechanical energy, typically magnetostrictive and piezoelectric ceramic. The power is output to the ultrasonic generator, and then to the ultrasonic transducer, and ultrasonic waves are generally generated by the ultrasonic derivation device.
The composition of the ultrasonic transducer includes an outer casing, a matching layer, that is, an acoustic window, a piezoelectric ceramic disk transducer, a backing, and an extraction cable, and is characterized in that it further comprises an array receiver, which is led by a cable, a transducer, Metal ring, rubber gasket.
The principle and function of the ultrasonic transducer: the ultrasonic transducer is a piezoelectric ceramic that resonates at the ultrasonic frequency. The piezoelectric effect of the material converts the electrical signal into mechanical vibration. The ultrasonic transducer is an energy conversion device. The function is to convert the input electric power into mechanical power (ie, ultrasonic waves) and then pass it out, and it consumes a small amount of power itself.
Types of ultrasonic transducers: can be divided into piezoelectric transducers, sandwich transducers, cylindrical transducers, inverted horn transducers, and the like.
