ABSTRACT:
A rotational speed transducer comprises a member which is mounted to rotate at a speed related to a rotational speed input. A lamp and a photocell are mounted in relation to the rotatable member such that light from the lamp is only reflected by the rotatable member toward the photocell each time a reflector portion or portions of the rotatable member comes into a particular position or positions with respect to the lamp so as to provide an electrical output, from the photocell, which is a measure of the rotational speed input. The reflector portions may be portions of a disc which constitutes the rotatable member.
