Piezo Power Ultrasonics | The History. The Mystery. The Science.

Rob's presentation explores the amazing world of Power Ultrasonics. He covers the history, the mystery, and the all-important science that make these tiny ultrasonic engines such a valuable technology used in a wide range of applications, including; • Sonar • Flow metering • Underwater communications • Ultrasonic drills • Ultrasonic cleaners • Friction welding of both plastics and metals • Cutting blades • Dental scalers • Fluid atomization Chapters 0:00 Intro 0:15 Applications 0:42 Beginning of ultrasonics - Curie Brothers 1:43 Paul Langevin 2:44 Langevin's Sonar Device 5:00 The Langevin Transducer 7:32 Ultrasonic Engine 9:43 Ultrasonic Horn Transmission 13:34 Langevin Transducer Applications 17:55 The Tonpilz Transmission 21:28 Tonpilz Horn Applications 21:50 Tonpilz Transducer Applications 24:16 Favorite Tonpilz Transducer 25:31 Resources and References From the Curie Brothers' discovery of the piezoelectric effect, through to the person who really got ultrasonics off the ground; Paul Langevin. Langevin's sonar device provided the foundational insight that made ultrasonic applications possible. The term “Langevin Transducer” is now used to describe any piezo-driven longitudinal resonator constructed by sandwiching piezo elements between two plates, commonly using a center bolt. Rob demonstrates how Langevin's ultrasonic engine works, its different permutations, including the ultrasonic horn, the Tonpilz transmission transducer (known as the "Acoustic Mushroom") that transmits acoustic waves in liquid, and more... *********************** We Are Here to Help *********************** Piezo.com designs & engineers high-value piezo modular solutions to integrate with your systems, please reach out and chat with one of our piezo experts if you'd like to know how piezos can help solve your challenges.
