  1. Piezoelectric ceramics ultrasonic transducer

The operating principle of the piezoceramics ultrasonic transducer is using the positive and backwards piezoeffect of the piezoceramics, namely interconversion of the electricity and mechanical vibration, to eradiate and incept the ultrasonic. When one electrical signal is exerted upon the ceramics, the ceramic body will engender mechanical vibration and eradiate the ultrasonic. While the ceramic body is under the process of the ultrasonic or other pressure wave, there will be the output of the electrical single.

Piezoceramics is used widely in various fields because of the piezoceramics having bigger electromechanical conpling factor and higher conversion efficiency, such as ultrasonic ranging?liquid level detection?crack detection?ultrasonic washer?ultrasonic atomizer?the lactescence of oil and water?the diagnoses and threatment of ultrasonic physic?hydroacoustic sonar etc. Our Ceramics have developed a great deal ultrasonic transducer which has successfully applied in military affairs?industry supersound?civil supersound etc fields. Many of our product are in the highest flight in our country, especially the research on the high strong focalize transducer of medical treatment and the transducer of hydroacoustic sonar.
