Systron Donner makes some wonderful, accurate, low force needed linear
pots, with a (IIRC) 1/4" or 1/8" or so shaft - 4" travel or something.
It's been years (These were used to measure ground movement under a snow
covering, with teflon shafts through the snow) - I know they coped with
LOW temperatures well, anyways - Give 'em a look.  Omega should have
something, I can stare at my set of books here if that'd help (I'll be
needing something like this soon...)  OTOH, I would not call those pots
"cheap"! - Could use the "Fader" pots they use for audio boards, even
tho audio taper, for this & just calibrate 'em?

Optical encoders, grey coded, also <G>
