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.
