Ultrasonic Cleaner
Ultrasonic cleaning is a means of removing dirt and surface contamination from intricate and/or delicate parts using powerful high frequency sound waves in a liquid (water/detergent/solvent) bath.
An ultrasonic cleaner contains a power oscillator driving a large piezoelectric transducer under the cleaning tank. Depending on capacity, these can be quite massive.

A typical circuit is shown below. This is from a Branson Model 41-4000 which is typical of a small consumer grade unit. The H and N are Hot and Neutral of the 115 VAC line. WARNING: Line connected input. Use isolation transformer for safety when troubleshooting.

hotwaterwizard, I think yo need to turn smilies of for that post.

Ha ha! That's a happy schematic!!! ;D ;D ;D

Can you remember years ago before you knew anything about electronics, when every schematic looked like snakes and ladders like that ASCII one looks like now?
It gives me the creeps! ;D ;D

Well I can remember months ago when I knew nothing about electronics ;D, and I came across these types of schematics and thought, (what the) and now seeing frowning faces in them, well that's just scary ;D.

 

[hotwaterwizard2]

I'm trying to make a schematic from this one.

Here is what I have so far.
Are there any misteaks?

So far so good hotwaterwizard, how are you drawing this?

Are you using a special program or are you using paint and putting some pre-drawn symbols togeather?

 

[hotwaterwizard2]

I do all of my drawings in Paint Brush.

Good work hotwaterwizard you're a credit to this community.

 

[Alun]

Well spotted tnk2k, I completely missed that!  ;D

The output's also pulsed 80kHz not 90Hz.

 

[hotwaterwizard2]

Here

 

[Alun]

You've still forgotten to put the kHz in, here I've done it for you.  ;DI can't see any other errors but don't take my word for it come back in a weeks time and see  ;D

 

[hotwaterwizard2]

LOOK AGAIN
I think you are looking at the first not the last because I did correct it!

 

[Alun]

You changed the 90 to 80 but you forgot the all important kHz part.  ;D

 

[hotwaterwizard2]

The frequency of the ultrasound is approximately 80 kHz for this unit with a maximum amplitude of about 460 VAC RMS (1,300 V p-p) for a 115 VAC input.


OOPS I Did forget
