  • Patent number: 10267691
    Abstract: A system and method determines torque applied to a rotating shaft by a load. Two sensors determine the rotation of the shaft at two spaced-apart axial positions. Controller(s) analyze two pulse trains associated with signals received from the sensors corresponding to rotation of the shaft at the respective axial positions under the load. The controller(s) determine a delta phase value for each pulse of one pulse train with respect to a corresponding pulse of another pulse train, and aggregate each delta phase value for a prescribed period of pulses to determine an aggregate delta phase value. The controller(s) determine a load phase value as a ratio of the aggregate delta phase value to the prescribed period, a total delta phase value as a difference between the load phase value and a reference phase value, and a torque value from the load based on the total delta phase value and physical parameters of the shaft.
