    • Power transmission monitoring systems includes rotation speed sensors mounted to hubs of a power transmission pulley. A sensor comprises a rotation sensing device, and a controller receiving rotation data therefrom and determining rotation speed of the pulley. A transmitter transmits rotational speed of the pulley to a receiver, which may include or be connected to a device that compares the rotational speed to rotational speed in transmissions from other sensors to determine slip in the power transmission system. The rotation speed sensing device may be an accelerometer, or a gravitational torque harvester. A harvester might include a rotor body rotating with the pulley and mounting induction coils, and a gravitational torque stator mounting an induction magnet and including an air vane damper maintaining the stator stationary with respect to the rotor, through air resistance. The transmissions may be employed to monitor, maintain and repair the power transmissions system.
