I have a variac with a motor controlled dial, controlled by a 0-10 V input. It will heat a filament which gets hot (1000 C). I want to design a control circuit that looks at the VAC/IAC = resistance of the filament, and adjusts the 0-10 V control voltage for the variac. Anyone want to network with me on this?
