ultrasonic piezoe transducer 50mm piezoelectronic ceramic disk
When the voltage acts on piezoelectric ceramics, it will produce mechanical deformation with the change of voltage and frequency. On the other hand, when a piezoelectric ceramic is vibrated, an electric charge is generated. Using this principle, when an electric signal is applied to the vibrator composed of two piezoelectric ceramics or one piezoelectric ceramic and one metal sheet, so-called double piezoelectric chip element, ultrasonic waves will be emitted due to bending vibration. On the contrary, when ultrasonic vibration is applied to the dual piezoelectric wafer element, an electrical signal is generated. Based on the above functions, piezoelectric ceramics can be used as ultrasonic sensors.
