High Frequency 20Khz Ultrasound Welding Transducer 

The transducer converts the ultrasonic frequency voltage from the generator into ultrasonic mechanical vibration of the same frequency by an inverse piezoelectric effect. It consists of a number of piezoceramic sheets sandwiched between two metal (usually titanium) blocks. A thin metal plate is formed between the sheet and the sheet to form an electrode. When a sinusoidal electrical signal is supplied to the transducer via the electrodes, the piezoelectric sheet expands and contracts, producing an axial peak-to-peak motion of 15-201 xm. The transducer is a precision device and should be handled with care.
