Ultrasonic Power Transducers

The ultrasonic power transducers is composed of central piezoelectric ceramic elements, front and rear metal cover plates, prestressed screws, electrodes and insulating tubes. This kind of sandwich transducer (also known as bolt transducer) produces stable ultrasonic wave when the load changes. It is the most basic and main method to obtain power ultrasonic driving source.

According to different designs, the shapes of ultrasonic transducers are mainly column type (the diameter of front and rear metal cover plates are the same), horn type (the diameter of front cover plates is excessively reduced by arc type), and column type structure with joints in the middle.

Characteristics of ultrasonic power transducers:

1. High performance: high mechanical Q value, electro acoustic conversion efficiency of more than 90%.

2. Large amplitude: the vibration speed is high, and the amplitude is more than 50% higher than that of the magnetostrictive transducer.

3. Heat resistance: high quality material, good heat resistance, low resonance impedance and low calorific value.

4. Firm structure: high quality standard steel bolts are fastened with high reliability.

Electrical parameters: unique production process, digital equipment processing and assembly, high parameter performance and good consistency.
