Hello all,
Currently in charge of the maintenance of a liquid formulation asset, I'm looking at making things leaner. We're having several pressure gauges on the plant and I'd like both the maintenance and production teams to be able to tell at a glance if the indication is within the standard working range or not.
Changing all the gauges for tailored ones is quite expensive so I'm looking at cheaper options, such as stickers my team could apply on the gauges directly.
The issue is that I can't seem to find suppliers for such an item.
Would you have names to provide?
Many thanks
Antoine

I've never seen what you're referring to as an off-the-shelf product.
There's an old racecar constructors trick that you can do with back-mount or bezel-mount gauges (but not bottom-mount). Rotate the gauges so that when they're operating at their nominal values, all the needles are pointing straight up. That will make any value that's off from normal immediately obvious.
The cheapest, easiest (and cheesiest) way to get indication markings is simply with a felt pen.
Next level might be using a thin tape line, like drafting tape or pin-striping tape.
For something easier to read try clear, tinted tape cut into wedges. If you're good with an X-Acto knife you can make multiple wedges in different colors to indicate operating ranges.
If you want specific, more complex graphics there are printable, clear, adhesive films available. You can get sheets of printable films from various office, graphical design or art suppliers. You can also get them made by many printers who do custom graphics.
If you have any high precision gauges, keep in mind that reading through an overlay can add parallax error. So be sure your operators are trained appropriately.

Tinted tape - like suggested, or just some arrows on the bezel to start.
Keep it simple.

We used paint marking pens on the glass of the gauge. This works very well and is very durable even in harsh environments.
The principle of "visual-at-a-glance" was to use a paint marker with green for the safe operating parameters and use red for the out-of-parameter areas so anyone could walk by and see if the pressure was within safe tolerances. Another words, if the needle is in the "green" all is good; if in the "red" we have a problem.
This was the standard that was used in two different factories that I was involved with and it is a very effective method.
Thanks,
Jeff

agreed. make it simple, if you need it you can modify the floor marking tape to do it! DIY yourself.

Try the 5Sstore.com and look under TPM/gauge marking labels
I have been using them quite effectively

Thanks all for all your answers.
@ Terry: brilliant internet adress. I can do it myself but with the right material.
Cheers

Antoine, Brady offers a software called MarkWare Lean Tools which includes functionality for designing red/green gauge labels on your computer. The labels are then printed to the GlobalMark label printer, which also cuts them out to size. The GlobalMark labels are thermal transfer printed and designed to withstand industrial environments. For more info, go to www.bradyid.com/visualworkplace and click on "printer and software solutions" under the Visual Workplace Product Solutions category on the left side of the page. I work for Brady, so if you are interested in arranging an onsite demo, let me know.

Search Google for Transparent warning film. There are a number of companies that supply the film and it makes this very easy.
