Ultrasonic transducer is also called ultrasonic vibaration son, , ultrasonic sonatrode, which an energy conversion device. Its function is to convert the input electrical power into mechanical power (ie, ultrasonic) and then transfer out, at the same time, it will consumes a small part of the power. Therefore, the use of ultrasonic transducers should be considered the most problems with the input and output matching, followed by the mechanical installation and with the size. In Jieda ultrasonic company, there are several different ultrasonic transducers , according to different frequency, they are 15khz, 20khz, 28khz. Welcome for more information!!
