Hi thanks for the video, I was a tech at a company that used 2" PZT-8 bonded to an aluminum plate. I measured to find an equivalent inductance to tune out the piezo capacitance and then could measure R. Now we could setup the amp with a conjugate matching circuit to match C and R of the transducer. We drove it with a 250 watts in a water bath. Our frequency was around 660kHz. My question, we always drove them at the low impedance point. I always wondered why. Is they pattern of the transducer any different between the low and high frequency point?
Thank you, sir! Great explanation. Could you tell me where should I study this ultrasonic 40 kHz transducer? Can you tell me any textbooks for driving circuits, equivalent models, and so on..,

Thanks Husain, all the best for Xmas and the New Year, cheers!
Thanks so much! Happy holidays to you and your family!

nice explanation
Thanks!

Thanks for your interest! I don’t have a book recommendation. That’s actually one reason I started making these videos.
Hi Dr...I'm Siti Huzaimah.
Dr, does the value of C2 and R1 change during the vibration? Thank you Dr
The value of R1 mostly changes. C1 and L1 have some change.
