Does anyone know of a manufacturer that has a large bargraph type display? It has to be readable from a distance so I'm thinking of a bargraph that's 1" wide by approx 12" high. Interface would be 4-20mA.
We once had to install a big, and I mean a BIG M****R F****R bargraph.
It was to stand in the middle of a place where there was acid from batterie crushing and fumes and oxide and mud and water and snow and explosive gaz ... You get the picture?
We installed a 6 feet air cylinder verticaly which pushed on a translucent plastic plate inside a transparent plastic pipe. All with a big spot light.
So there we had our own 6 feet tall bargraph. And it was explosion proof.
