max temperature for touch screens....

[[email protected]]

Can anyone tell me which kind of touch screen will be better to be
used in kitchen area?
According to what I read, projected capacitive touch screens seem
better.
Can these touch screen withstand high temperatue...might be 120C.
Let me know your suggestions.

Air conditioning?

Air conditioning?

Doesn't matter. The right answer is not likely for ANY consumer or
commercial product.

Hell, even military specs do not generally exceed 70C handling
capacity.

I am sure there is a ruggedized version out there though for rough duty
situations.

What kind of kitchen are you putting these in? You won't see 120C in
either residential or commercial kitchens in locations where contact is
possible due to the applicable consumer or workplace safety regulations.

I have a double convection oven with a control panel mounted such that
heat rising through the appliance might exceed internal component
ratings. The solution is a small cooling fan that circulates air through
the electronics space.

what if hot oil or boiling water(temp will be less than 120, still...)
comes in contact with my touch screen(may be not for long time...5-10
seconds) ???????? then what ??? that spot/area gets damaged?
I am just considering a possibility....

Well then, you need to specify the conditions where the screen will be
exposed to those conditions.

Manufacturers probably won't have figures for this kind of environment.
You might have to find out what kind of material the screen is made of
and at what temp it will melt. You could model the thermal conductivity
of the structure to see how fast the heat from a droplet will be
dissipated, but it will probably have a minor impact on anything other
than the front surface.

Boiling water will probably be the worst case, as H2O has a higher
specific heat than oil.

At 120C, who's going to touch it?

Thanks,

Either don't put a touch screen in your kitchen or train yourself not to
pour hot boiling liquids on your equipment.

Good Luck!
