Abstract
The present invention provides an absolute shaft encoder to measure both the angular position of a shaft from a given radial axis and simultaneously or in sequence to record the number of completed rotations of the shaft passing through a given radial datum axis, the encoder consisting of a first wheel and signal pick up means generating unique incremental signals such that the radial position of the shaft can be recorded and displayed and actions initiated; at least a second wheel providing unique position signals from a further signal pick up; an indexing mechanism operating between the first and second wheels such that the indexing device rotates the second wheel through an angle equal to the angle subtended by each sector at the wheel center wherein, the first wheel is arranged to operate the indexing mechanism whereby for every completed turn of the first wheel the second wheel is indexed two or more times providing two or more position signals to the second wheel's pick up device.
