Cling film over HMI displays

cardosocea · Jul 13, 2018

Hello,

My manager showed me an old style MPxxx HMI from Siemens where the operators cover it with cling film to ensure they don't mess it up.

I'm now considering using one of their new Comfort Panels so am wondering if it would also work with cling film over the top or if the new touch technology wouldn't like it.

Has anyone seen this in the past? Or has any experience on how to protect HMI displays in messy industries?

Siemens has protective films available for the comfort panels, I've had good results using them.

We have them made and sell a lot as the are cheap and a lot cheaper than replacing the screen or the HMI, they are just a really big cell phone or tablet cover

We only have them for the Allen Bradley PV's but can have any size made, im sure you can have them made over there... if not let me know the size and I will check the price for you

So long as it is a Resistive touch screen then you should be OK with Folix Screen protectors, like this:

I just buy the one for the biggest screen at the lowest price and then cut them to size. They can be a bit fiddly getting them on without leaving air bubbles caused by dust particles, but it does make for a clean HMI. Folix supply a 'lint free' cloth and a spreader thingy to help. Looks a lot neater than clingfilm, but is more expensive.

Cool.

I guess I'll go down this route and buy a few touch pens to avoid having to replace these on a daily basis too.

That works also... I sell a lot to a large Pizza chain and they use them for their screen on the cash register, just make sure you use a sharp razor and cut it a little big, if the edge is not perfect then it can give you false touch inputs but if its out of the touch area it does not matter

use a sharp razor

You made me think about cutting the stuff, one of these makes for easy right angles:

I have a cheap 'personal' rated one but didn't want to steer anybody wrong with bad advice. You can trim down to a millimetre or less, which was good for the old Beijer HMIs that had a recess for the screen.
