Selecting Ultrasonic Transducers for Industrial Cleaning Applications

Ultrasonic cleaning systems consist of three parts: the ultrasonic generator, the transducer, and the cleaning tank. The generator produces an electric signal and the ultrasonic cleaning transducer converts the signal into compression waves into the cleaning solution. The waves then produce cavitation bubbles that do the scrubbing action of the components to be cleaned.

The role of the transducer is quite crucial for the cleaning of components, parts, and tools. It produces compression waves through the piezoelectric material that expands and contracts when subjected to the electric signal. The transducer changes the height of the piezoelectric material with the help of the electric signal that comes from the ultrasonic generator. That way, the transducer produces compression waves when its metal surface, tightly bonded to the surface, vibrates at a selected frequency.

Ultrasonic cleaning transducers need to be heavy, rugged and durable enough to withstand severe vibrations and immersion in cleaning solutions, as well as to generate powerful compression waves. Their surfaces must also be designed to resist pitting due to the action of cavitation bubbles.

Kaijo offers transducers that are heavy, rugged and durable. They are hermetically sealed in 316L polished stainless steel housing and are designed to withstand immersion in cleaning temperatures up to 100 degrees Centigrade.

Ultrasonic cleaning transducers are available in bolt-on, immersible or mounted versions. Immersible versions are independent units connected to the generator via a cable can be moved and placed anywhere in the cleaning tank. Mounted tranducers are integrated into cleaning tanks and are usually purchased for specially designed cleaning applications. Bolt-on transducers are similar to mounted, but are bolted onto the sides or bottom of cleaning tanks in single or multiple-unit configurations.

Kaijo’s ultrasonic cleaning systems range in frequencies from 26 kHz to 2MHz. Their variable power output has maximums of 600W or 1200W. Kaijo is able to evaluate a customer’s needs and propose the right custom solution.
