ABSTRACT:
A device for detecting a difference between the speeds of rotation of two revolving shafts wherein a movable body is laid out between two dead-head systems mounted opposite one another and caused to rotate by each of the shafts in such a way that the body is displaced between two end positions, either suddenly if the sum of the tensions of the two systems is positive, or gradually if such sum is negative so as to measure, for example, the difference in speeds in a twin engine jet or to produce control devices or devices to trigger automatic systems.
