Title: Transducer for measuring speed of rotation
Inventor: HERBERT SAMUEL WILLIAM
IPC: G01P3/486
Filed: 1983-06-17
Abstract: A transducer arrangement has an annular disc 32 which is, for example, mountable on a bearing housing 12 secured within a hollow cylindrical roller 10 which is engageable with the underside of a return run of a continuous conveyor belt such as a coal conveying belt in a mine. The disc 32 has an inner periphery from which extend angularly- spaced projections which, upon rotation of the disc 32, move relative to a sensor device 20 so as to successively interact with it. The device 20 can be an electrooptic device having two elements, one being a source of electromagnetic radiation and the other being a sensor responsive to the radiation. The projections are successively movable between the elements. The device 20 operates, in response to the successive interactions, to produce electric pulses at a frequency corresponding to the speed of rotation of the disc 32 and thus to the speed of the belt. <IMAGE>
