A position sensor is any device that permits position measurement. It can either be an absolute position sensor or a relative one. Position sensors can be either linear or angular. Positioning Sensors are finding their way into more handheld, medical and industrial devices every day. Knowing the position and orientaion of a device or tool is critical for any modern control system to work accurately. Examples are as varied as a smart phone, a drilling platform, or the attitude control of a Boeing 777.
