What is an ultrasound emitter?

An ultrasonic transmitter is an essential component in ultrasonic cleaning systems, capable of generating and transmitting high frequency acoustic waves at medium cleaning levels, generally a liquid. This causes the phenomenon of cavitation, where the formation and collapse of microbursts in the liquid produce an effective cleaning action on the submerged surfaces.
 

Ultrasound Emitter Technical Function

The process is started with an ultrasonic generator, which converts the electrical energy into high frequency signals, typically in the range of 20 kHz to 40 kHz. These signals are based on a piezoelectric transducer, which transforms the electrical energy into mechanical vibrations. The transducers are only manufactured with piezoelectric materials like PZT-4, designed for their high energy conversion efficiency.

The mechanical vibrations generated by the transducer are transmitted through a radiant element, such as a plate or a sonotrodo, through the cleansing liquid. The interaction of these ultrasonic waves with the liquid induces the formation of microbursts which, when collapsed, generate powerful cleansing capabilities to eliminate contaminants from the surfaces of the objects submerged.
