The high mechanical quality of ARS's piezo transducers ensures that these sandwich-type ultrasonic transducers offer high electro-acoustical efficiency and low heat generation. The mechanical connection of the piezoelectric elements assures a large amplitude output. ARS's standard ultrasonic cleaning transducers are available in two frequencies: 28 kHz, 40 kHz. ARS also offers a 50 kHz power transducer that can be used in a variety of applications, including as a fabric cleaner, nebulizer, atomizer, for ultrasonic mixing, or for cell disruption.

Cavitation occurs when the vibration of a transducer surface interfacing with a liquid (usually water, but possibly a water / organic solvent mixture in an ultrasonic cleaning application) is sufficient to create a partial vacuum that exceeds the vapor pressure of the liquid, and bubbles form at the vibrating surface. Cavitation is a desirable feature in ultrasonic cleaning or liquid vaporizing applications, but obviously must be avoided in signal transmission applications.

In ultrasonic cleaning applications, effects of the dimensions and configuration of the water tank, the water load, and the thickness of the bonding layer affixing the transducer to the water tank combine to slightly reduce the frequency of the transducer, and give rise to several additional resonances. Despite these negative factors, however, a well-designed transducer, incorporated in a well-designed circuit, will operate near its resonance frequency.
