Place of Origin:
The ultrasonic high-power transducer is composed of a central piezoelectric ceramic element, front and rear metal cover plates, a prestressed screw, an electrode sheet and an insulating tube. This bolt-fastened transducer generates stable ultrasound when the load changes, which is the most basic and main method to obtain a power ultrasound drive source.
◆ High performance: The mechanical Q value is high, and the electro-acoustic conversion efficiency is over 90%.
◆ Large amplitude: The vibrator has a high seismic velocity, which is more than 50% higher than that of a magnetostrictive transducer.
◆ Heat resistance: The use of high-quality materials, good heat resistance, low resonance impedance, and low heat generation.
◆ Strong structure: It is fastened with high quality standard steel bolts and has high reliability.
◆ Electrical parameters: unique production technology, digital equipment processing and assembly, high parameter performance and good consistency.
Main Problems of ultrasonic transducers
Common problems in use are chip cracking, weakness, overload, electrode pad ignition, electrode chip cracking, heat generation, leakage waves, and wafer misalignment.
The causes of such problems can be classified into three categories.
Firstly, there is a problem with the customer ’s Generator or horn assembly, or our transducers and horns are defective, or the tuning problem.
The first case: the customer's ultrasonic generator or horn.
We recommend that customers actively find out the reasons, or communicate with our company's technical staff, and improve as soon as possible.
The second: We have a problem with our ultrasonic transducer and horn
This can happen, but it is less likely to be found. Our company specializes in the production of various kinds of high-power ultrasonic transducers. The quality of all products of horns is at a high level in China. And also with ISO9000 quality certification system and strict process and inspection, the quality of our ultrasonic transducer products is guaranteed. The qualified rate of our factory products is 100%.
The Third : There is no problem with both products, but they do not match.
This is the most common, that is, the customer's generator is good, the ultrasonic transducer is also good, and the assembly is normal, but the parts do not match. The main parameters causing the mismatch are the frequency and capacitance of the ultrasonic transducer. In response to this situation, the solution is for the customer to adjust the matching parameters of his driving power supply to suit our ultrasonic transducers. The second method is for the customer to study the chassis and the original transducers carefully. Parameters, in short, as long as you can provide accurate parameter requirements, we can guarantee to provide you with the right transducer.
