  • Shaft sensor assembly for angular velocity, torque, and power
    Patent number: 6439067
    Abstract: In a preferred embodiment, a shaft sensor for a machine, the shaft sensor including: first and second disks, fixedly orthogonally attached to a portion of a shaft of the machine, the portion of the shaft being subject to torsion, and the first and second disks being operatively attached to the portion of the shaft at spaced apart locations along the portion of the shaft; and a sensor assembly, including first and second sensors, disposed in sensing relationship with the first and second disks to sense relative position of the first and second disks resulting from torsion of the portion of the shaft and to output a signal representative of at least one parameter related to torsion of the shaft. In another preferred embodiment, the shaft is discontinuous and the first and second disks are attached, respectively, to first and second portions of the shaft and have a resilient member disposed therebetween.
