Ultrasound Converters
Ultrasound Converters result from a stack of special ceramic disks, using the Piezoelectric effect.

In a somewhat similar way to a resonant helical spring, the Converter disk stack is subject to axial length variations.
However, ceramic Converter’s resonance takes place at ultrasound high frequency with extremely
minute amplitude.
Except for the reaction delay, its response is in step with the electric oscillator’s frequency.
