35W Ultrasonic Transducer From Banggood.com

Ultrasonic transducer from Banggood. Right now I burned 2 W driver, but even at such small power it vibrate like crazy (read: high efficiency). My mistake is to expecting it to work by transforming low voltage into high voltage by using transformer pulled out of computer power supply. Okay, it worked day before, but in the meanwhile I recharged battery, so current goes crazy high. Just one volt difference pull too much current and small MOSFET showing almost instant smoke. Proper way to powering it is by using 100-300V rectified voltage and driving with high voltage MOSFETs. Still, there should be impedance matching transformer/coil. Sorry people, I can't show you how it works, but I hope soon to make proper driver. stay in touch.
Transducer in question is this one ($4.58US):
BTW, if you make your own ultrasonic cleaner, please DO NOT forget to put some liquid (water for example), else transducer(s) may shatter due to standing waves.
Oh, BTW... did you spotted mistake on the scope, and the reason why it burned? Between oscillation is about 3 mS ON state - reason why MOSFET staying in conductive state and has "heavy inductive load". So, current... eh... my mistake... sorry... Now, I changed that and it works okay. Maybe I will make another video, but anyway - those MOSFETs are weak.

Don't they usually have a tuned horn?

[sumitsaha]

Can you tell me what is the output current and voltage of it?

[felipemendonca]

Hi ! \what did you use to fix it on the bowl? Thanks!!

[okaysingh]

Hi, Thanks for your video. Can you tell what is the maximum allowable voltage through this transducer?

[WEYHARRY]

Hi
Could you tell where you got the water proof type small transducers please. Been looking for that size transducer for a long time.
Thankyou

[Matt]

Great video. How did you stick the disc onto the aluminium? Epoxy? Also did you solder direct onto the disc?

[misterleogame]

How to install positive and negative connection?

[Gary-Seven-and-Isis-in-]

You're hoping to stick a transducer to a Non Stick pan ?

Hi, I am a sound engineering student at Argentina. Lately I've been working on hydrophone designs for cetaceans sounds. I used 160kHz piezoelectric crystals and achieved an acceptable result for Narrow Band Ultrasonic Frequency clicks emitted by dolphines. However, I had a poor response in audible frequencies. If I want to use a hydrophone for audible frequencies, should I use crystals with a resonant frequency bellow, within or above the range of interest??? Why???

[grangerdanger]

Can you please provide circuit information please

[Solarzack]

hello, what gel would work as a good conductor for dry substance? also please get back with simplistic idea for a model to experiment different outputs of power. kindly

[solartonytony]

...mine 'cooked' ... model cd 2800, 35W element ...epoxy to ss tank bottom ...any way to replace it ? ...peace

[samuelhanks]

thank you I have been trying find something like this

[rubenvandervleuten]

Hi, would you be able to share the circuit you got it to work with. I'm trying to achieve the same, but have problems getting it to work. Also what voltage were you running through the transducer?

[ankeshjaisansaria]

Can this be placed at the bottom of jar and used for measuring the level of water in the jar?

[johnaweiss]

It worked once. Sorry, could not recharge the batteries for this video!

[kaluvanhariharan]

Sir. how did you fix ( paste the ceramics)?

[Luciano-jgws]

I put hot water in my ultrasonic cleaner, big mistake the transducer is toast.

[omsingharjit]

Hello can you tell me one challenging Thing ?
As seen here ....
Ultrasonic horns are both bolted and glued at the same time and location so how can you remove it without any distraction ?
Because for un screwing it you have to turn but you can't because it's ceramically glued and you can't even twist back and forth because of bolt and also its base is just thin pice of metal which can easily band !!

So how it's profectionally done ?
I need that horn from cleaner for handheld Ultrasonic for some purpose .
