The transducer converts high-frequency electrical energy into high-frequency mechanical vibrations. And it contains several piezoelectric ceramic discs sandwiched under pressure between two metal blocks. Between each disc is a thin metal plate, which forms the electrode. When a sinusoidal electrical signal is fed to the transducer via the electrodes, the discs expand and contract, producing axial vibrations.
ultrasonic transducer is an energy conversion device whose function is to convert the input electrical power into mechanical power (ie, ultrasonic waves) and then pass it out, while it consumes a small amount of power (less than 10%). Therefore, the most important consideration for using ultrasonic transducers is the matching with the input and output terminals, followed by the mechanical mounting and mating dimensions. There are many types of ultrasonic machinery on the market, and customers must provide accurate and reliable indicators to ensure that the ultrasonic transducer products provided by the company can be matched with your company's ultrasonic machines to achieve the best performance.

Problems that can arise when using ultrasonic transducers:
Common problems in use are wafer cracking, weakness, overload, electrode pad ignition, electrode chip cracking, heat generation, leakage, and wafer misalignment.
The reasons for such problems can be classified into three categories. One is that the customer's drive power or mold and assembly problems, the second is that our transducers and horns have problems, the third is that both products have no problem, but do not match.
1. our ultrasonic transducer and horn have problems
This will happen, but the possibility of discovery is relatively small. Our company specializes in producing all kinds of high-power ultrasonic transducers. The quality of all products of the horn is at a high level in China. At the same time, we have ISO9000 quality certification system and strict process and inspection. The quality of our ultrasonic transducer products is guaranteed. The pass rate of our factory products is 100%.
2. the customer's drive power or mold has a problem
We recommend that customers actively find the cause or communicate with our technical staff to improve as soon as possible.
3. the products of both parties have no problem, but they do not match.
This is the most common, that is, the customer's drive power is good, the ultrasonic transducer is also good, the assembly is normal, but the parts do not match. The main parameter causing the mismatch is the frequency and capacitance of the ultrasonic transducer. In response to this situation, the solution is to adjust the matching parameters of the driver's power supply to suit our ultrasonic transducers. The second method is to carefully study the various chassis and the original transducers. Parameters, in summary, as long as you can provide accurate parameter requirements, we can guarantee to provide you with the right transducer.
