Apparatus (100) adapted to provide an indication of an angular position of an input member (106) over multiple turns includes at least two rotatable members (104A -104D) configured, in use, to rotate in accordance with rotation of an input member (106), and at least one sensing device (114A) configured to measure and output an angular position of at least one of the rotatable members. The rotatable members are configured to rotate simultaneously but at different rates. The apparatus further includes a device (114) configured to use the angular position measurements from the at least one sensing device to produce an indication of an angular position of the input member over multiple turns. |
