PRINCIPLE OF ULTRASONIC SENSOR

 

Piezoelectric ultrasonic generators actually work with the resonance of a piezoelectric crystal. The internal structure of the ultrasonic generator has two piezoelectric wafers and a resonant plate. When a pulse signal is applied to its two poles, the frequency of which is equal to the natural oscillation frequency of the piezoelectric wafer, the piezoelectric wafer will resonate and drive the resonance plate to vibrate, thereby generating ultrasonic waves. On the other hand, if no voltage is applied between the two electrodes, when the resonator plate receives the ultrasonic wave, the piezoelectric wafer is pressed to vibrate, and the mechanical energy is converted into an electrical signal, at which time it becomes an ultrasonic receiver.
