3200W ultrasonic transducer with converter and booster low impedance

ultrasonic transducer, also called ultrasonic vibrator, is a device that converts electrical energy to mechanical energy by the piezoelectric effect of piezoelectric ceramics. In the process of ultrasonic welding in various applications, the matching between each ultrasonic unit is extremely important, the unit such as ultrasonic generator, transducer, welding horn to form a complete ultrasonic system which can be referred to as a match.

Frequency matching between the ultrasonic transducer and generator is one factor that affects the welding performance. First of all, because the ultrasonic transducer can only work at its own resonant frequency, so the ultrasonic generator, booster and the mold (welding head) should all work at this frequency. In general, this difference is no more than ±0.1kHz, the smaller, the better. It is strongly recommended that the frequency of the supporting welding head be lower than the transducer's frequency about 0.1KHz(small-signal frequency). That is to say, if the frequency measured by the small signal of the original transducer is 14.85KHz, then the ideal frequency after connecting to the welding head is 14.75KHz. At the same time, it should be taken into account that after the transducer is connected to the welding horn, the resonant frequency summit of the system should become very sharp, that is, the bandwidth is very narrow, while the mechanical quality factor is very large, a small shift in frequency can cause a large increase in impedance, which could lead to the ultrasonic generator's overload protection or broken ceramics, etc. Therefore, the importance of frequency matches can not be over-emphasized.

FAQ:

Q: What is the structure of the PZT transducer?
A: The transducer consists of a housing, a matching layer, a piezoceramic disc transducer, a backing, an outgoing cable, and a Cymbal array receiver.

Q: What is the lifetime of the transducer?
A: General speaking, it depends on the quality of the transducer. All of our transducers are highly processed and adopt superior PZT ceramics. The lifetime will be more than 5years.

Q: What are 1/2-20UNF means?
A: It is a kind of American thread code, 1/2 means 1/2 inch of the diameter, and 20 means there are 20 threads per inch.

Q: Do you have a parameter sheet for every transducer you ship?

A: Yes, we do, each transducer we supply comes with a specific parameter sheet and its own serial no.
