Fluke Repair

What specific materials are involved? Metals? Plastics? Maybe a picture?

You will find that everyone has a favorite adhesive that's "the best one out there".

Fact is, there are many adhesives which will work.

Epoxies, cyanoacrylates silicones all might work. More details please.

It would really help to advise if we had a picture:

1. Take a picture and get it on your hard drive.
2. Start another thread like you started this one.
3. Type your question.
4. Click the button above.
5. Click Browse.
6. Find the picture file and click Open.
7. Click Submit.

Knowing the materials of the nozzle and sensor body would help as well.

Overview

Where the piece needs to attach.

How it should look...

The piece that needs to be re-affixed.

As for the material of the piece it appears to be some sort of metal, exactly what I'm not sure.

Hope that can give some more insight in.

Thanks,

Thanks, cems,

A couple more questions:

Is the face of the sensor plastic? Looks like it might be polyethylene.

What is the max pressure of the module?

Like Lyn says there are a lot of different ones that will work, but will depend on the answer to these as well.

It looks to me like the pressure range on the sensor input is -12 to 30psi, it also lists the max NDT pressure @ 60 psi.

From the feel of the sensor I wouldnt say its plastic by any means, feels almost chalky to the touch similar to the edges of the board itself. Not having a lot of experience with PCB's or anything similar its tough for me to say.

I probably would us a two part epoxy that is rated for a variety of materials - something like this. (disclaimer)

Lay as even a bead as you can in a circle on the face of the sensor, concentric with the hole, but stay away from the hole; you don't want to use too much either so as not to plug the hole.

Good Luck!

"Looks like it might be polyethylene."

Or acetal, polyester, Nylon, etc. Could be anything, that's the problem.

I'd be inclined to suggest a cyanoacrylate from the hobby shop. Something "designed" for adhesion to thermoplastics. It was attached at one time, probably with a CA adhesive in production quantities applied by a robot. I'd just apply a very thin bead around the outside of the metal part and put it back in place. After that cures, you might want to apply a small bead around the outside of the metal part for added sealing. Breathe on the exposed "glue", it likes moisture to cure.

Good Luck.

Really with the othre guys here, but, I'd try a really small bead of hotmelt.

Quickly! Carefully!

Cheers,

Stu.

Thanks for the help guys I'm going to attempt this fix in the near future and hopefully she works...

Well,

True to form, you have gotten three different opinions on how to repair this. I'm skeptical of the hot melt, frankly, because of the delicate nature of the repair and the fact that one part is metal.

Whatever you use, be sure to clean the two pieces with alcohol. Nothing stronger, since we don't know what type of plastic we're dealing with.

Please let us know what you use and how the repair went.

Good Luck, don't glue your fingers together.

Excellent advice. I would have said exactly the same if I'd thought of it.

Diligent cleaning is probably more important than choice of adhesives, in most cases.

Yup!

Oh I'm not planning to use hot melt...the sensing element is quite thin I dont want to apply any sort of heat to it.

Any chance on finding a source for the sensor? I guess I would try to repair it first, but if that fails, time to look for a part number on the sensor, and see if there is any sources for that. Fluke had to buy it from someone. Down side to sensor replacement might be calibration of the unit, it probably is dependant on the sensor, and a new one would mean re-cal would be in order.
