With the availability of ultrasonic cleaning equipment operating at frequencies from 20kHz up to over 250kHz and the capability to use more than one frequency in a single piece of ultrasonic cleaning equipment, users inevitably and rightly question the optimum frequency or frequencies for their cleaning applications. The popular and most touted notion is that …
Note – Before we start, there is a nomenclature conundrum when it comes to the term “ultrasonic transducer.” Through convention, transducer elements, the individual devices that produce ultrasonic vibrations (much like an individual radio speaker), are commonly called “transducers.” A number of transducer elements working in parallel constitute a transducer array but may be called …
Ultrasonic cavitation and implosion provide a unique benefit in cleaning unmatched by other means. So much so that ultrasonic cleaning is often used as a benchmark to judge the effectiveness of other cleaning techniques. The major factors in cleaning are Time, Temperature, Chemistry and Mechanical Effect or Motion (TTCM). There are other acronyms for these …
