Leakage Detection Using UV Lamp

Maybe, though it would be easier to use a dipstick.

But this would only tell you that you have a leak, not where it actually is!

Naturally. Where the leak is will become evident by using the Mk.1 eyeball, with the added bonus of, if there isn't a leak, there's no point in looking for one.

Slam-dunk here.

So its more the search for hair-line cracks.

There must be some use of UV light?

Maybe solve this if here is too easy!

Google Ultra Violet Leak Detection.

It is used in vehicles, hydraulic systems, air conditioning systems, etc.

Best regards,

If we have to ask we probably cannot.

UV trace is also added to circuit board conformal coatings and used as an inspection tool to check for completeness of coating.

Dear Sir,

Thanks a lot for your suggestion's.

i feel it is right method to find leakages using talc powder.

can we point out slight seepage/pin hole leakages using talc powder?normally we feel problem pointing out leakages at gasket/gasket joints/loose fasteners in transformers.

can you please suggest me how to avoid these leakages and how to point out these leakages if occured.

these seepage are very minute approximately 2 drops per day.

please help me in these regard.

Hi

you certainly can and the lamp and dye are sold as propriety items. The large manufacturers of tractors and construction kit have used them for a long time now to test for leaks on the end of the production line. The fluid shows up with a luminous glow. It is very effective on new machinery as there is not a lot of grease or oil about and therefore any signs of leakage are easy to spot.

Thank dear Oliver,

can i know which dye they use?

it will great for mt experiment if it succeeds in my project.

Hi

I regret I do not know what dye is used as I bought a unit many years ago and it came with the dye. The lamp works without using the dye but the glow is not as strong. Most manufacturers do not bother with the dye as it is too much bother to put a quantity in each new machine so they just use the lamp with good results.

PS If you go on the web you may be able to find out what the dye consists of.

just use OBA, optical brightener agent that textile manufacturers use .It should help you to detect leakages. The agent is UV sensitive and you can see a "glaring" spot .Better try in a low light environment or in a dark environment.

The agent is also used to detect contamination in long lines/pipes..etc

Dear All,

thanks for your valuable suggestion's.

Can i use these on painting surfaces?normally our transformer is painted with 150 microns.
