Abstract
The present invention is directed towards a hydraulic power unit including a housing, an internal hydraulic power means, an external hydraulic power means, and a mechanical power shaft associated with the hydraulic power means. In addition, the hydraulic power unit comprises a transducer adapted for measuring torque mounted in the housing in a non-contact relation to the mechanical power shaft adjacent a portion of the shaft imposed with a magnetic field. The hydraulic power unit further comprises a controller associated with the transducer to monitor the measured torque and adjust the operation of the hydraulic power unit accordingly.
