I need to measure the position of an object which moves slowly (< 1Hz)
along one axis. Max travel is about 6 inches. I want to read its
position to a resolution about 1 part out of 1024 (10 bits), but the
absolute accuracy only needs to be 1%. I can mechanically attach
something like a pushrod to the object.
I'm familiar with LVDTs and the old NE5521 chip, but dont want to
spend a $1000 for a 6" LVDT.
Anybody got any ideas?
