An ultrasonic cleaner is a metal container that has ceramic piezo transducers attached to the side or the bottom of the tank. These transducers convert one form of energy to another. They also change size when an electrical signal excites it. When the transducer is excited it increases in size and causes the side or the bottom of the container to move.
When an electrical generator emits a high frequency signal, the transducer offsets rarefaction and compression waves in the liquid. With this rarefaction cycle, the liquid is torn apart. Consequently a vacuum cavity is created in the liquid. The cavities fluctuate in size, but when the cavity reaches a certain size, it cannot retain its shape. When this happens, the cavity collapses, creating an extremely high temperature of 5,000 degrees Celsius (9,032 degrees Fahrenheit), and a jet of plasma hits the object in the container. Millions of these bubbles are created and collapsed every second.
These bubbles are what clean the object in the tank. The jet of plasma that hits the object causes the dirt to come off, and can be increased by adding a cleaning agent to the tank.
Now that you know how an ultrasonic cleaner works, here are a few tips to get you started:
- Make sure you always use a basket to clean your items. Never put them on the bottom without one.
- Choose the right type of ultrasonic cleaner. There are many types out there. They can range from jewelry cleaners to laboratory equipment.
- Find the right ultrasonic cleaner solution before you begin. You can choose from general purpose solutions, industrial strength solutions, electronic solutions, and many others. Many ultrasonic cleaners should be used with water. When cleaning circuit boards, distilled or dionized water should be used. But if you’re using the cleaner for other applications, like dentistry, tap water is fine.
- Used water or cleaner solution should be treated with 10% bleach before being disposed.
