I like the idea of replacing my analog displays with something digital, thereby removing my tanks from my 12 volt set up. Mine are old VDO gauges and they work.
I understand the theory of resistance (VDO senders are 0-90 ohms), so that isn't really the proplem, but is there a way to integrate what I have without removing the tanks/guages from the 12volt house bank? Seems that most ADCs are isolated, so is it a simple case of limiting the voltage to 5 volt (or 3.3volts) from 12?
