PZT 4 Material Piezoelectric Sensor Ultrasonic Ceramic Ring Hemisphere Element Piezo Ceramic Material Disc

Piezoelectric ceramic devices are widely used not only in industrial and civilian products, but also in military applications. If piezoelectric ceramics are used as underwater acoustic transducers as a pair of bright “eyes” for nuclear submarines, they can smoothly carry out underwater navigation, communication, reconnaissance of enemy ships, cleaning enemy mines, and other tasks; A piezoelectric fuse made of piezoelectric ceramics can Ignite and detonate destructive weapons such as armor piercing shells; Another example is the piezoelectric gyroscope made of piezoelectric ceramics, which is an indispensable “rudder” in aviation and aerospace, and so on. Ultrasonic treatment of wastewater and toxic water generated by piezoelectric ceramic transducers. Ultrasonic motors with small radial dimensions, high output torque, and strong controllability; Ultrasonic sensors such as anti-theft, height measurement, car collision prevention, remote control switches, and robot distance measurement; Special attention should be paid to servo displacement brakes, optical strain gauges, strain gratings, ultra precision guiding mechanisms, cutting and grinding error compensation brakes, hydraulic servo valves, etc.
