<p>PURPOSE:To allow deep part probing for petroleum, geothermal resource, etc., by enhancing sensitivity and SN ratio of horizontal vertical magnetometer units and disposing two sets of array type horizontal magnetometers vertically above and below an array type vertical magnetometer thereby enhancing the sensitivity and SN ratio of a tri-axial magnetometer as a whole. CONSTITUTION:An element 1 of an array type horizontal magnetometer comprises a core 3, a main winding 4, a feedback winding 5, a Teflon coil end 6, an electrostatic shield 7, and a winding terminal 8. Ten pieces of the elements 1 are combined alternately in XY directions to form array type horizontal magnetometers 100, 200. An array type vertical magnetometer 2 comprises a mu metal core 11, a feedback winding 13, sixteen unit pi windings 12, and seventeen partition boards 14. The tri-axial magnetometer comprises the array type vertical magnetometer 2 disposed in the center, the array type horizontal magnetometers 100, 200 disposed at the opposite ends, and a main output connector 15 connected with a cable for delivering magnetic field components in XYZ directions being measured to a ground unit. Highly accurate and compact unit allows deep part probing.</p> |
