Identify this device?

Yep, looks like the one I use for supplementary humidification (and atmosphere!) in my bedroom

Am I the only one troubled by knowing this fact?

Very useful info, thank you!

No, I do not have the little power supply. What kind would I need and where would I get one?

Thanks again.

I've heard of them but never seen one until now. I do know about ultrasonic cleaning devices for pH probes though. That one had a signal generator separate from the immersed unit. The power supply you mentioned might be more than just a power supply. It might also be the source of the ultrasonic signal.

'Might be wrong so please correct me .

Hey, Vulcan...

No. They're made as a single unit, water-proof, and just takes DC power. You can buy these things complete for about $40.00.

As I said before, if you get your finger too close while it's operating underwater, the little bastard will bite your finger really well! It's not a shock, it's the ultrasonic signal trying to do to your finger what it's doing to the water!

Looks like a transducer used as a fogger sold in pet stores. Used to humidify the air for certain reptiles. Check a pet store for the power supply.

I showed the picture to my father; he says these are used in oriental gardens to create a climatic effect for Bonzais? He saw one in Korea ca. 1952?

I don't think they go back quite so far! In 1952, it would have had tubes and be about the size of the family car!!!

Anyway, their basic use has been as a device for creating a mist that comes from a vessel of shallow water. Mostly used about 5 years ago to add spooky or mystic mood to all those desktop waterfalls they sold.

I don't know but wouldn't it make a racket or a buzzing noise?

I worked with ultrasonic cleaner tanks and they buzz in a most unfriendly frequency which makes it hard to work with it for long.

Wouldn't want that on my desktop, too much distraction if you ask me.

Mind you, it would be nicer than Windows and probably more bearable.

These things are silent to the human ear.

Very Good! Hahahahahahaha!!!

Damnit! I wanted to say that! I couldn't of said it as well anyway.

"...you will notice a raised portion whch provides finger grip for moving it around."

That is actually a magnifier, for reading lines of fine print, etc.

Still funny tho.

I bow to your superior resolution.

ok, it's a ruler. I've heard of inches and millimeters for rulers. But what the heck is a "Canberra?" What is the coversion to mm, please. And what is the abbrieviation? Cb?

Canberra is a company that makes radiation detection and measurement instrumentation. It's now part of the Areva group. See http://www.canberra.com/

Have to thank everybody for the valuable info and the general entertainment.

And I do work for their Canada division.

It is an ultrasonic evaporator. The very first answer from Vermin is the correct one. By the way, I use a similar device to increase relative humidity in winter, indoors for better comfort. Tried many other kind of humidifiers before, they all failed shortly, or were a pain to maintain with the hard water I have. The ultrasonic vaporizes the water along its mineral content, requiring a good vacuuming and dusting once in a while.

Vermin rarely gives straight answers and when he does I figure he has actual experience, which in this case he reports of. Therefore it is likely he has told you what it is and what it did to his finger.

Is it some sort of load cell/washer - a very small one?

I'm going to take a guess, but it is only a guess, YMMV.

The window is the thing that gets me thinking in this direction. It looks like beryllium. Beryllium has only a few industrial uses, one of which is as a neutron generator. I suspect you have in your possession a neutron generator. when powered up, they generate a spray of neutrons out the beryllium window. when powered back down, they are no longer radioactive (for the most part, there may be some incidental neutron activation that decays quickly). they are used for a number of processes including radiography. I suspect this device was designed for that purpose. I would suggest you NOT power it up.

I would also add that the body of such a device would probably be made of tungsten or lead. Since you stated that the device is very heavy for it's size this also seems to indicate it is not an ultrasonic transducer.

That is an Ultrasonic transducer which atomises water to create a nice foggy mist. That particular module contains 3 colored LED's that cycle colors. The black assembly jutting out the top is the water level sensor which will shut the device off if the water level drops too low. It requires 24 VDC at 1.5 amps to operate. Imported from China, works well as a humidifier with a LED light show to add ambiance.

Hope this helps.

Have you seen those decorative bowls that make fog? They call them misters, ionizers, etc. If you plug it in and put in under water, you'll see.

I spy with my little eye something beginning with a S = S-tray (Ashtray)

I actually see a methane, CO2, O2, CO etc sensor used in mines.

The gold strainer on top with a sort of membrane underneath to keep water out, (and flames in) with a pelistor sensor(s) inside. (thin platinum coiled wire with catalytic bead around it)

The cable leading out must be plugged into electronics. Because methane are lighter than air the sensor must be placed at a high spot, hence the handle to be attached to a broomstick.

It is heavy to enable disposing heat generated by the burning methane

Looks like a seismic sensor or accelerometer.

Does it measure a resistance reading? A low ohms (10,000 ohms or less) is likely an inductive device whereas a high or infinity reading is likely a piezo-electric one.

Put the connector on a o-scope and thump or shake it to see if it puts out any voltage proportional to the force used.

Bill,

Read the other posts... It's been properly identified about a bazillion times already.
