6results about How to "Avoid false signals" patented technology

The invention discloses a magnetism gathering type fluxgate sensor probe which comprises a magnetic core, an exciting coil, a pickup coil, a pickup coil framework, a feedback coil and a feedback coil framework, the magnetic core is dumbbell-shaped, the exciting coil is wound on the dumbbell-shaped magnetic core, a groove matched with the magnetic core in shape is machined in the pickup coil framework, and the feedback coil framework is arranged in the groove. And the dumbbell-shaped magnetic core wound with the excitation coil is arranged in the groove. The fluxgate probe can be configured to be a single-axis or three-axis fluxgate probe, a pair of pickup coil skeletons is arranged in each axial direction of the three-axis fluxgate probe, and the three pairs of pickup coil skeletons 4 along the X axis, the Y axis and the Z axis are perpendicular to one another and are placed in a feedback coil skeleton in a spatial # shape. The magnetic measurement sensitivity and precision of the fluxgate probe can be effectively improved, the X-axis, Y-axis and Z-axis parts can work independently, and the problem of mutual interference when the X, Y and Z components of a magnetic field are measured is avoided.
