High Amplitude 20KHz Ultrasonic Converter Branson 902J Replacement

Description:

SP TECH offers a large number of converter types in order to achieve the best results for each application. The converters transform the electrical oscillations produced by the ultrasonic generator into mechanical sound waves.

Ultrasonic converters are fitted with 2, 4 or 6 ceramic discs, depending on the application. The latter are predominantly used in the packaging industry and for continuous use. The oscillations are best transferred to the ultrasonic workpiece through the ceramic discs, thereby reducing process times and ensuring high process reliability. The top quality housings are very strong and long-lasting and have various HF interfaces.

Production core step:

Because piezoceramics are weak in tension, a static compressive prestress must be applied to prevent the piezoceramics from experiencing tensile stresses when the transducer vibrates ultrasonically. The prestress also assures that the piezoceramic interfaces make good contact so that the acoustic waves are transmitted well with minimum loss. The compressive prestress must be sufficient to prevent the piezoceramics from ever experiencing any ultrasonic tensile stress and prevent any lateral piezoceramic slippage. In the manufacturing process of ultrasonic transducers, the size of prestressing plays a decisive role in quality.

The piezoelectric ceramic impedance and frequency will stabilize with the prestress's increase. A larger prestress can reduce the impedance of the transducer. If the piezoelectric ceramic is not sufficiently clamped, the transducer impedance will become larger. But larger is not better.
