| 摘要 | A system for sensing stress in a ferromagnetic material is provided. The system includes at least one magnetic flux device configured to induce a conditioning magnetic flux in the ferromagnetic material. The system also includes a sensor positioned proximate to the ferromagnetic material. The sensor includes a core, at least one excitation coil configured to induce a second magnetic flux in the ferromagnetic material, and at least one detector configured to detect changes in the second magnetic flux. | ||

| 主权项 | 1. A system for sensing stress in a ferromagnetic material, said system comprising: at least one magnetic flux device configured to induce a first magnetic flux in the ferromagnetic material; and a sensor positioned proximate to the ferromagnetic material, said sensor comprising: a core;at least one excitation coil configured to induce a second magnetic flux in the ferromagnetic material, wherein the at least one excitation coil is configured to be driven simultaneously by both a direct current (DC) source and an alternating current (AC) source; andat least one detector configured to detect changes in the second magnetic flux. | ||
