Product Description

50*17*6.5mm Pzt8 Piezoelectric Ceramic Rings Disc Piezo Ring Ceramic For Hot Selling 20KHz Ultrasonic Welding Transducer

in the design of ultrasonic transducer, various factors should be considered, such as acoustic impedance, frequency response, impedance matching, acoustic structure, vibration mode and conversion material, as well as how to design and coordinate these factors to achieve the optimal value of electroacoustic conversion. As an energy transmission network, piezoelectric ceramic transducer has the problem of energy conversion efficiency.The principle of piezoelectric ceramic transducer is that when pressure or tension is applied to the ceramic plate, opposite polarity charges will be generated at both ends of the ceramic plate, and current will be generated through the circuit. This effect is called piezoelectric effect.
