摘要： PROBLEM TO BE SOLVED: To provide an optical current direction detecting sensor and optical current direction monitoring system which are not affected by ambient environment, facilitates multi-point monitoring, does not require any electric power source, and are rigid and inexpensive. SOLUTION: When a float 6 is slid along a pipe 3 by the current direction of a fluid, a permanent magnet 7 to be embedded embedded in the float 6 comes close to a Faraday sensor 4 (5) and separated from it. When the float 6 comes close to the Faraday sensor 4 (5), signal light incident onto the optical fiber 24 (25) of the Faraday sensor 4 (5) becomes extinct. When the float 6 is separated from the Faraday sensor 4 (5), signal light incident onto the optical fiber 24 (25) of the Faraday sensor 4 (5) is internally reflected and returned in the same optical path. By detecting the returned light from each of the Faraday sensors 4 and 5, the current direction and presence or absence of the fluid are detected.

摘要： PURPOSE:To prevent the selfish movement of an internal light shielding body even when the light shielding body oversteps the boundary where an external magnet can restrict the movement of magnetic body on the light shielding body side by separately providing an internal magnetic body or magnet between the external magnet and light shielding body side magnetic substance or magnet. CONSTITUTION:An internal magnetic body 14 or magnet is separately provided between an external magnet 8 and light shielding body side magnetic body 7 or magnet so as to attract the displaced magnetic body 7 to the magnetic body 14 or magnet to a locked state. It is preferable to provide locking magnets on both sides of the moving range of the magnetic body 14 or magnet. When such a constitution that the magnetic body 14 or magnet 8 can move within a fixed range in accordance with the movement of the light shielding body side magnetic body 7 is formed, a light shielding body 5 which is displaced by the magnetic body 14 or magnet can be locked to the displaced state even when the magnet moves widely and oversteps the range in which the magnet 8 can control the body 5. When the magnet 8 is restored to its original state, the body 5 is also restored and malfunctions are prevented.
