In fact, there is little difference, if any, between ultrasonic converters and ultrasonic transducers. The terms can be used interchangeably and how they are used often depends upon which company is manufacturing and selling the product. Mostly, they are referred to as converters, though there are just a few companies that market the product as a transducer.
Whether called a transducer or converter, the device does the same thing, which involves creating mechanical movements from electrical impulses. The device emits an electrical impulse at a specific frequency and, as it travels across the ceramic portion of the device, it’s converted into a vibration. Once threaded onto a booster, that vibration can be modulated or transferred to the attached horn.
In its turn, the horn makes contact with a part that is intended to receive the vibration. The horn places pressure upon the part throughout the duration of the vibration and maintains this contact after the movement has stopped. The duration of the vibration is called weld time and the period immediately following is the hold time. Depending on the equipment in use, such as the Dukane sonic welder, the weld and hold times can vary. It will largely depend upon the ceramics in use on the piece and the part receiving the vibration.
The size and duration of the vibration can be increased as well, but it will depend on obtaining larger equipment. Specifically, a larger horn and booster will be needed to create the larger vibration, but it will mean locating a greater source of power. This can also affect the converter, as it will cause more stress to be placed upon it. This may cause the converter or transducer to wear out faster.
Regardless of what it’s called, the ultrasonic converter is essential to this process of changing electrical impulses into physical movements. To obtain a quality product, it may be best to obtain your converter from a dealer which specializes in ultrasonic equipment. This will ensure customer service representatives will be knowledgeable and able to answer your questions. Relying on a reputable dealer can help ensure the converter you buy is able to handle your needs.
