28KHZ 1000W Industrial Ultrasonic Spot Welding Machine Transducer Cutting Skin Scrubber Cavitation Pressure Transducer

The function of a transducer is to convert electrical signals into mechanical vibration signals. There are two physical effects of converting electrical signals into mechanical vibration signals. A: Magnetostrictive effect. B: The inverse effect of piezoelectric effect. The magnetostrictive effect is commonly used in early ultrasonic applications, with the advantages of high achievable power capacity and the disadvantages of low conversion efficiency, difficulty in production, and difficulty in large-scale industrial production. Since the invention of piezoelectric ceramic transducers, the application of the inverse effect of piezoelectric effect has been widely adopted. Piezoelectric ceramic transducers have the advantages of high conversion efficiency and mass production, but their disadvantage is small power capacity. Existing ultrasonic machines typically use piezoelectric ceramic transducers. A piezoelectric ceramic transducer is formed by clamping the piezoelectric ceramic between two metal front and rear load blocks and tightly connecting them with screws. The output amplitude of a typical sensor is approximately 10 μ M.
