Infra-red sensors? radiation wave length is correlated to temperature and does not depend on colour or shine, at least within some limits.

The best would be to organize a test with a IR thermometer supplier.

how about thermal imaging?

Due to the changing appearance of the wire, (Light/Dark & Shiny/dull) Thermal imaging was discounted. Do you know any reason (Emissivity) to re-visit this process???

About 2 years ago I was looking into color imaging (quality control on a sorter for fruit)High speed and high Volume too.

and was surprise the extend of speed, quality and senitivity it had offered. I just put that out there.

Thank you for the input!!!

My company (www.4TTC.net) routinely offers Thermography solutions to customers. You are right; some of the things possible with this technology are amazing. However, in the hands of someone not properly trained in the use of the equipment (Emissivity, set-up, etc.) many false readings are considered good. Add the fact that each location has different conditions and considerations, and the "Technician" will have to adjust (Calibrate) the equipment for every reading. In addition, this equipment is not cheap; budget is always our limiting factor...

Have a great day!!!

There is a commercial section of CR4.

This forum doesn't usually engage in commercialism to the extent that you have. Your posts always include a sales pitch. I'm sure all your products and services are probably top notch, but we don't normally sell ourselves here.

Sorry, I did not mention that IR was tried with mixed results...

In addition, Cost is a driving factor. I know this process is being done every day, I just need to find the best industry solution. Why re-invent the wheel...

Thanx for your input...

Ron,

I'll be honest. You're hosed. I have tried for a couple of years to find a similar solution, for a similar application (galvanized wire temperature measurement, out of a multihole drawing die). There is nothing I could find to reliably and CONSISTENTLY measure temperature on a relatively fine wire (.250" and less) while running. Contact would be the best, but not at 400 m/min. You're also talking about cost as being a driving factor... The process is being done every day, using simulation software, then limited trials to confirm. The idea is to freeze the process so that nothing change. That is a better way and it can be done. Otherwise, you're wasting your time. Explain that to your boss who put you up to this.

Oh, its not your boss who put you up to this...You are actually selling temp measuring devices, but you don't know what you're doing and trying to get help from people you're suppose to educate... git!

Thanx for the words of encouragement!!!

Have you ever heard about the Ircon "CHF" system? (This is a non-contact system for temperature sensing for wire drawing that I have found in my search.) I was just curious if you looked into this system and perhaps had some feedback on it's use…

Perhaps some else has used this system and can offer some additional assistance…

Thanx again for your reply… ;-)

Please Note: I am not selling temperature measurement systems! One person took a (Unintentional) post of mine and distorted it into my "Commercialization" of this site!

Ircon is nice and reliable, but the CHF system I think only goes up to about 275 deg C (530 F). Plus, you said cost is a very important factor. Ircon is anything but cheap.

Thank you to everyone who helped me get a handle on this project!!!

Have a great day!!!

I am Sorry if this sounds like a commercial; IT IS NOT!!!
