Abstract
A sensor assembly for measuring the displacement or position of a movable member. The sensor assembly utilizes two or more smaller, less accurate sensors to perform the function of a single, more accurate larger sensor. The resolution of each of the smaller sensors is increased by configuring the sensor system such that the maximum travel of each sensor in a direction covers half or less of the travel of the moveable member being measured. Each sensor then moves in an opposite direction to return to its original position for the remainder of the travel of the movable member. Utilizing a cam follower system, two sensors generate a set of output signals at each position of the moveable member in a one-to-one correlation over the range of travel of the moveable member.
