Selecting an Ultrasonic Transducer for Your Cleaning Application

An ultrasonic cleaning system consists of a generator, an ultrasonic transducer, and a cleaning tank.

The role of the ultrasonic cleaning transducer is to transform an electrical high-frequency signal from the generator into ultrasonic sound waves in the cleaning solution contained in the tank.

Kaijo's ultrasonic cleaning transducers are made up of an electrical section that receives the electrical high-frequency signal from the generator and a mechanical section that vibrates at a high frequency. Once received, the electric signal is applied across piezoelectric crystals which change the signal into vibrations.

When the transducer is immersed in the liquid or cleaning solution, these vibrations result in corresponding ultrasonic waves in the solution. These ultrasonic waves travel through the liquid as compression peaks and troughs. Cavitation bubbles form in the troughs because of the low pressure, and they collapse again in high-pressure peaks. As bubbles collapse, they release an extremely powerful jet of cleaning solution that dislodges dirt, grime, and other forms of contaminants from the surface of the parts that are being cleaned in the solution.

These bubbles create a fast and effective cleaning action without damaging the underlying surface; they can clean even in the most inaccessible areas of the parts being cleaned. The result is rapid, efficient and thorough cleaning.

Types of ultrasonic cleaning transducers:
  • Immersible transducer – A more flexible type of transducer, it can be placed in any tank in the cleaning solution. It can be positioned horizontally or vertically, as long as it is completely submerged in the liquid.
  • Bolt-on or mounted transducer – It is permanently installed onto the walls or bottom of the cleaning tank.
