Abstract
An incremental rotary transmitter is proposed for mounting upon the free end of a shaft. The transmitter comprises a pulse disc rigidly secured to the shaft and a relatively stationary scanning disc freely mounted on the same shaft. The scanning disc is thus subject to the same flexing oscillations or errors in true running of the shaft as the pulse disc, so that measurement errors due to eccentric movements of the pulse disc are substantially reduced.
