10 X 5 X 2 Mm Piezo Disc Transducer Ultrasonic Vibration Piezoelectric Ceramic PZT -4
When the voltage is applied to the piezoelectric ceramic, it will produce mechanical deformation with the change of the voltage and frequency. On the other hand, when the vibration piezoelectric ceramic, it will produce a charge. Using this principle, when given by the two pieces of piezoelectric ceramic or a piece of piezoelectric ceramic and a metal piece a vibrator pressure, called bimorph element, an electrical signal is applied to will due to bending emit ultrasonic vibration. On the contrary, when ultrasonic vibration is applied to the piezoelectric element, an electrical signal is generated. Based on the above function, the piezoelectric ceramic can be used as an ultrasonic sensor.
Piezoelectric ceramic wafer body
Piezoelectric ceramic wafer is a structure simple and lightweight electrical devices, because of its high sensitivity, no magnetic field spreading spillover, without using a copper wire and magnets, less cost and low power consumption, convenient mass production, etc. won the widespread application. Suitable for ultrasonic and acoustic wave transmitting and receiving, a large area of the piezoelectric ceramic plate can also used to detect the pressure and vibration, the working principle is using the reversibility of the piezoelectric effect, the audio voltage is applied to its, to sound.
◊ High efficiency
◊ High amplitude:
