Waterproof Ultra Sonic Answered

does anyone know of any type of ultrasonic that is waterproof and can go underwater? cause im trying to make a fog machine using the ultrasonics pieces and water since my dad bought something that worked like what i described. anyone know of any that can be underwater or some design that will work underwater using a regular ultrasonic you see on robots?

. IIRC, most fog machines, U/S cleaners, &c use piezoelectric ceramic crystal drivers, which are reasonably waterproof.

k i found out it uses a ultrasonic transducer but u need help finding one that is able to turn water into mist. i know it needs a really high frequency level but idk what it has to be at and where to find them. anyone have an idea on both?

Are you asking using about an ultrasonic transducer that creates mist like in a portable room humidifier or an ultrasonic radar-like sound measuring device? I think most fog/smoke machines usually heat/burn some kind of oily liquid.

yea somwthing like that where it turns the water into mist due to the high frequency the small piece (from what my dad said was a ultrasonic piece) makes. but what i dont understand is from the one my dad showed me (cause it was something he bought out of a magazine and it really looks cool) doesnt have the mini grill looking thing like the one you can buuy off the shelf for a robot project. the one my dad has some solid plate over it instead of a grill. my question is are they 2 different ultrasonic pieces that were made differntly or is it just water sealed to make the mist?

Look at this ultrasonic fog generator or search on that topic. Depending on the amount of fog you want to make, the more $$$ it will cost. Maybe you can figure out how to do it. I don't know if you will need circuitry to control the oscillating/vibrating on the ultrasound module to make it just right for fogging water. Don't know if is the same thing out of a robot-sensor.

yea its something like that. i just hope i only need to put voltage to make it vibrate than have to make a board for it.

Smoke machines can work on watered down antifreeze. Just don't try it.
