What is an Ultrasonic Generator?

The electronic ultrasonic generator is a power supply. It transforms AC electrical energy from a power source such as a wall outlet, to electrical energy appropriate for energizing a transducer at an ultrasonic frequency. In other words, the ultrasonic generator sends high-voltage electrical pulses to the transducer.

The ultrasonic generator working principle is to send electrical energy pulses to the transducer, which transforms energy into mechanical (pressure) waves in the cleaning fluid for vibratory ultrasonic washing action.

While the ultrasonic frequency of 40 kHz is by far the most commonly used frequency for ultrasonic parts cleaning, some applications do require a lower or higher frequency for best results. For example, larger, heavily soiled items may use a frequency of 20 kHz since this yields bigger, stronger cleaning bubbles but fewer bubbles per second. At the other end of the spectrum, some very small, delicate items may require higher ultrasonic cleaning frequencies, up to 200 kHz. In general, a higher frequency permits a higher level of intricate detail to be cleaned.
