UltraSonic Transducer.

Hello everyone,

Like i mentioned in my other post here :
https://www.electronicspoint.com/fo...er-interface-for-arduino.292520/#post-1795054
I want to build my own arduino based fuel injector cleaner. Further more i have seen theese ultrasonic cleaners that work pretty well. Does anyone know how to use ultrasonic transducers ?
I found a few on e-bay :

What is their rated voltage and current, how can i drive them. I suspect that it takes 30-40Khz pulses of high current but im not sure.
Any insight is welcomed . Thank you !

Hello,

On the page of the transducer it is stated to be an 28 kHz version.
For that you will need a driver like this:

Unfortunately is is designed for 220 Volts operation.

I bet the transducer itself runs on lower voltage. The driving circuit is there to turn the 50/60Hz mains supply to 28Khz . If that is the case then i could use the arduino to produce the 28Khz and mosfets to supply the pulsed voltage to the transducer.

Hello,

The transducer you are showing looks like the one on this page:

Well its probably the same i suppose. So the transducer and driver circuit are what i need.
