MAGNET MEASUREMENT SYSTEM

摘要

A magnetic field measuring system is provided to reduce measurement errors and to exactly measure the intensity of a magnetic field by preventing a sensor installed at a sliding member from being inclined. A magnetic field measuring system includes: a frame(1) having an electromagnet(M) exposed to the upside; a pair of guide rail units(2) arranged on the frame in a line about the electromagnet; a pair of moving members(3) installed at the guide rail units to move along the longitudinal direction; a sliding member(4) of which one end is slidably combined to one of the moving members across the longitudinal direction of the guide rail unit and the other end is slidably joined to the other one across the longitudinal direction of the guide rail unit, having a sensor(41) detecting a magnetic field of the electromagnet; a pair of first transfer screws(5) disposed in parallel with respective guide rail units and thread-combined to the moving members; a pair of first motors(6) rotating the first transfer screws, respectively to move the moving members, and synchronized with each other; and a second motor(7) sliding the sliding member.
