I need some information regarding fuel gauges. I am in the throes of
developing a converter to enable fuel gauges intended for use with variable
resistance (rheostat) type sensors to work with capacitive sensors, as used
in our Lancairs.

Why? One may ask. I hate digital (numeric) readouts. Nothing, IMHO, beats an
old analog type pointer. I also think a row of LEDs is a poor substitute for
a needle. So I bought a set of 1 1/2" Mitchell gauges that look really
spiffy and are affordable. I have made several measurements and can
interface my converter to the gauge but I'm expecting linearity will be an
issue.

So the help I need is a schematic of the innards of a typical, preferable
Mitchell, fuel gauge.

I'll make the final design available to anyone who'd like to build it for
their use.

Pat
