Abstract
An arrangement for sensing the rotary movement of a rotary means is disclosed, said arrangement comprising a sensing member which is arranged to be subjected to a predetermined actuation when the rotary means has rotated a predetermined number of revolutions, and two rotary members which are arranged to rotate at mutually different speeds, directly proportional to the rotary speed of said rotary means, and which are provided with actuating means arranged to cooperate with each other so as to cause said predetermined actuation of the sensing member when the two rotary members reach a predetermined relative position.
