Abstract
PURPOSE:To obtain high performance regardless of variance and temperature characteristics of the magnetic force of a permanent magnet by providing a subordinate magnetic circuit on the outside of the permanent magnet of a closed magnetic circuit. CONSTITUTION:A device 11 has the closed magnetic circuit 12 constituted by connecting permanent magnets 2 to both end parts of a couple of parallel magnetic plates 3 and providing subordinate magnetic circuits 13 and 14 on the outside of the permanent magnets 2. Then the leak magnetic flux 6 in the closed magnetic circuit 12 is detected by a magnetic detector 4 which moves in the lengthwise direction of the closed magnetic circuit 12. Further, magnetic flux 5 flows to the magnetic plate 3 of the closed magnetic circuit 12, so that magnetic flux 15 flows to the subordinate magnetic circuit 13 and magnetic flux 16 flows to the subordinate magnetic circuit 14. Consequently, the high performance is obtained regardless of variance and temperature characteristics of the magnetic force of the permanent magnets.
