摘要： A magnetostrictive measurement system having one or more encoded polarized magnetic regions disposed circumferentially about a shaft, wherein adjacent magnetic regions along a section of the shaft have opposing polarities. In one embodiment the shaft is hollow and the encodings are interiorly disposed while in another embodiment the encodings are on the exterior surface of the shaft. There are one or more sensors, such as contact sensors, disposed about the shaft wherein the sensors enable measurements of at least one of bending moments or torque sensing. The sensors can also include non-contact sensors measuring the magnetic flux densities caused by the alternating magnetic fields from the rotating shaft. A processing section is used to process the sensor measurements, wherein the sensor measurements are used to compute at least one of shaft power, torque, speed, and bending moments.
