The ultrasonic transducer consists of a central piezoelectric ceramic element, front and rear metal cover plates, prestressed screws, electrode sheets and insulating tubes. This kind of sandwich transducer (also known as: bolt-fastened transducer) generates stable ultrasonic waves when the load changes, and is the most basic and main method to obtain a power ultrasonic drive source.
According to different designs, the shape of the ultrasonic transducer mainly includes column type (the diameter of front and rear metal cover plates are the same), horn type (the diameter of the front cover plate is excessively reduced by the arc type), and the column type has a section in the middle.
Model | SP-2540-4D |
Frequency | 40Khz |
Output power | 500Watt |
Joint bolt | M8 |
Ceramic disc Diameter | 25mm |
Quantity of Ceramic discs | 4pcs |
Capacitance | 4~5nF |

Application | Spot Welding Machine |
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.
Ultrasonic transducer,ultrasonic generator and ultrasonic horn constitute a whole ultrasonic system, which can be widely used to do welding in various kinds of industries.
1. Low resonance impedance
2. High mechanical Q value
3. High electroacoustic conversion efficiency
4. Good stability, low heat
5. Good consistency of frequency and static capacity
6. Provide customized service
7. One year warranty
Other Transducers Display:
1. Do you have it in stock?
We only have common products in stock but not for the nonstandard products.Because all the products need make based on customers' different requirements.
2. Could you advise to us the design based on our special requirements or based on our object samples?
Of course, we can do. Please tell us your idea or your application.
If you have sample object, send it to us or send detail pictures.
3.How long do you make the order product?
Common products for 7days, big qty and none standard products for 20days.
4. How about the quality?
We have export to many other customers from all over the world, the feed back is good,quality is the first of our company.
5. Could you do OEM?
Yes, of course. We can produce according customers' requirement, just send us your requirements and design of drawing and sample.
6. Could we as your agent?
Of course. We are looking for sole agent in Country who have the willing to cooperate with us for long business term.
