We are attaching a potentiometer to an axle to indicate arm height. We are using a 100ohm / 10 turn pot. We are getting values of 4.5V to 5.0V over the entire range of 10 turns. We are worried that that is not enough of a range of values because...the pot will only be turning about 2 turns(not the full 10 turns it is designed for). We anticipate only having a range of 4.5V to 4.6V to use for feedback.

Will it work even with the small range of values?

Will a different potentiometer give us more of a range?
