piezoelectric ceramic discs for ultrasonic cleaning machine

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.

 

Piezoelectric ceramic chip is a simple and lightweight electrical device. It has been widely used because of its high sensitivity, no magnetic field spread and overflow, no need of copper wire and magnet, low cost, less power consumption and convenient for mass production. It is suitable for transmitting and receiving ultrasonic wave and infrasonic wave. Large area piezoelectric ceramic chip can also be used to detect pressure and vibration. The working principle is to use the reversibility of piezoelectric effect to apply audio voltage on it to generate sound.

 

 

Piezoelectric ceramic is a kind of functional ceramic material which can convert mechanical energy and electrical energy into each other. At the same time, it has positive and negative piezoelectric effect. The piezoelectric ceramic wafers produced by Changzhou ultrasonic Electronics Co., Ltd. are mainly used in ultrasonic probe, ultrasonic medical treatment, ultrasonic flowmeter, automatic control and other fields. With outstanding performance and complete specifications, PZT piezoelectric wafers and new composite piezoelectric wafers can meet different requirements.
