A motion transducer includes a rotatable wheel, a drive assembly that engages a movable rod in contact with the circumference of the rotatable wheel, and an encoder that measures the rotation of the rotatable wheel and that encodes information relating to the rotation of the rotatable wheel. Linear motion of the movable rod causes rotation of the rotatable wheel, the angular displacement of the rotatable wheel being proportional to the linear travel of the rod.
