Cheap 4-20ma display

[micky]

Anybody know of any small displays that will range 0-100% with a 4-20 signal? Looking for something to put in a demo box.

Never used - but looks the part & is cheap.

Saw those, but the range is 0-1000. If I can't find any thing else I may go with them.

I have used these in the past - The PR Electronics unit is quite reasonably priced in NZ not sure of the pricing in the US.

Also you could look towards a basic temperature/process controller to do the display, the Omron E5CC basic unit has a scalable 4-20mA as an input option and is under NZ$300. Should be even cheaper at your end of the world.

for demo and test i am using pm435 with a 9 volt battery ( all displays separate battery) they cost around 6 euro are new.
with a simple resistor of 50 ohms you get a nice signal of 1 volt.
the dot is adjustable.

You can buy them cheaper, but these are industrial and economical. Proven too.

These panel meters are really cheap and small for demo/test boxes.
