Ten Things You Should Know About Piezo Discs And Cylinders
piezo electric sensor transducers utilize the piezoelectric effect and the inverse piezoelectric effect to realize mutual conversion of electric energy and acoustic energy,piezoelectric ultrasonic transducer is one of them, it is a underwater acoustic device that use it for underwater sounding and receiving ultrasonic . The two ends of transducers can sense charge under the action of sound waves, that is the sound wave receiver, If an alternating electric field is applied to the piezoelectric ceramic,sometimes the piezoelectric components will get thin ,sometimes it will get thick, meanwhile,it will produce vibration, sound waves, which is ultrasonic transmitter.Piezoelectric transducers are also widely used in the industry,such as navigation, marine detection, precision measurement,ultrasonic cleaning, solid flaw detection and medical imaging, ultrasound diagnostics, and treatment of ultrasound diseases and so on. Another application of piezoelectric transducers today is the telemetry and remote control systems, example is piezoelectric ceramic buzzers, piezoelectric ignites, ultrasonic microscopes.
Ultrasonic motor is that uses inverse piezoelectric effect mounting to produce ultrasonic vibration,the micro-deformation of the PZT material amplifies through the resonance.By vibrating and moving parts to drive.Compared with the traditional ultrasonic motor,it has the advantages of low cost, simple structure, small size, high power density and low speed performance, large torque, fast response, high control precision , no magnetic field and electric field, no electromagnetic interference and electromagnetic noise characteristics piezoelectric bimorph element.
