Abstract
A system and method for measuring torque on a rotating component, comprising of signal-producing components which are applied to the rotating component, and a means for obtaining the signals produced by said signal producing components, in which at least two signal producing components are applied to the rotating component with some linear separation between the two signal producing components and their corresponding devices for obtaining signals produced, such that torque applied to the rotating component will cause a change in phase between the signals received from each of the signal-producing components and thus permit the measurement of torque based on this change in phase; one embodiment of this invention comprising two magnetic rings, one at either end of a driveshaft, with sensor coils placed near to each magnetic ring such that an alternating electrical current is produced, the comparative phase between these currents permitting measurement of torque on the driveshaft.
