How Do You Build An Ultrasonic Cleaner?
An ultrasonic cleaner is a tank that has an ultrasound generating transducer built into the side or lowered into the fluid. A transducer is a material that will physically change shape when excited by an electrical pulse. When the transducer is excited it increases in size and the tank bottom or tank side will move. This movement creates a compression wave in the liquid of the tank, thus creating the ultrasonic cleaner. An electrical generator that puts out a high frequency signal will cause the transducer to rapidly induce compression and rarefaction waves in the liquid. This will create a vacuum cavity within the liquid. The vacuum cavity will grow larger and smaller as the compression waves continue. When the vacuum cavity reaches a certain size the cavity coffee can no longer retain its shape. At this point, the vacuum cavity will collapse. There are millions of bubbles created that then collapse every second in this ultrasonic cleaner tank. These collapses are what clean the part
