my poorly made driver from vevor blew the traces and finging this is a wonderfully simple replacxement
Very good and simple explaination. Thanks for the video
Great video. Thank you so much. Do you have a video explaining how to increase the efficiency?
Would be interesting to see how the receiver circuit looks like too
Super! Thank you very much!
Hello, have you made a video about drive transducer using si5351? I feel that i've watched that video, but now i dont know where is that video on your channel
Hi There
Iam developing a Medical Ultrasonic cleaner and would like to reach out to your experience for some generator designs.
How to drive this hesentec rank e transducer?
Dear Husain, I m wondering if you could cover the amplification part since most of the piezo transducer will require power amplifier. What is the minimum amplification required for one piezo transducer? How to determine suitable amplifier ?
You need to determine your power requirement. If your amplifier meets the power specification, you may need a transformer to increase the voltage (step up) or a transformer to incresae the current (Step down)
Why not charge and discharge using zero crossing by charging to 5V, discharging to -5V?
How much oomph you can put into this and other transducers would be good as their data sheets seem very ambiguous about input and output, interesting though. PDF's for these ultrasonic transducers suck.
I agree. However, transducers are not well characterized expect as characterized in the final assembly by the end user engineer. They are not like a MOSFET. They are more like buying a bar of steel which you will make into something else with it's own properties based on what that thing is.
Hi Husain
Does any piezoelectric crystals increase or decrease Toto volume . or do they just change shape while preserving total volume? if so which crystals produce the most change in total volume , if not are you aware of any material that changes total volume when voltage is applied?
Lead free ceramics have low poisson's ratio. That means they change volume more than PZT materials with an applied voltage, relatively.
At 39:33, on the actual breadboard, it looks like the 5V Signal from the Frequency Generator is going to the Drain on the MOSFET, not the Gate? Shouldn't that red wire running from the probe go to the left-most pole on the MOSFET? Or am I mistaken?
Great set of videos, btw -- very helpful!
I watched it and you are right - the signal generator should drive the leftmost pin. Thanks!
@@ultrasonicadvisors Thanks! I’m new to this and was trying to make sure I understood how it all worked.
What voltage should we be using for langevin transducer ?
In general, from 40V to 400V
Can I do this via Microbit?
