An opposing field sensing element, for ferromagnetic cable inspection Is disclosed that uses magnetic flux sources and a magnetic flux sensor to detect anomalies in ferromagnetic cables. An array of opposing field sensing elements may be used to non-invasively inspect systems that contain ferromagnetic cables such as conveyer belts and the like. The opposing field sensing element is small and compact, and immune to vertical axis flutter and disturbances of the ferromagnetic cable being inspected. In addition, the opposing field sensing element does not magnetize the ferromagnetic cable being, inspected such that, interference with other sensing and control systems is minimized. |
