I have a circuit that needs to electrically output a pressure value and display it using analog dial gauge. First I wanted to use regular round ammeters but they don't look like "real" pressure gaugeish. Have a look to get an idea about what I mean
Needle in a pressure gauges is usually mounted in the center and have a much more wider travel sector. The best I can think of is to get an auto tachometer, print a new dial face with pressure scale and remove all unnecessary control electronics from the tachometer leaving only galvanometer and a precision resistor inside. Then I plan to drive it with PWM. There is another type of tacho that uses a small stepper inside. This should be also fairly simple to drive.
I don't want to reinvent the wheel, so want to ask if anybody knows about a product that does exactly same job, i.e. pressure gauge simulator?
