IPC: G01N31/00
Filed: 1992-09-29
Abstract: PURPOSE:To shorten the hydrogen detecting time by constituting a hydrogen detection sensor by coiling an optical fiber, so as to detect hydrogen based upon the increase of optical transmission loss when the optical fiber absorbs hydrogen. CONSTITUTION:For a sensor part 11, the portion of an optical fiber 12 whose coating was removed is coiled up, and fixed with a coating 13 whose material is identical with the fiber 12, thus the fiber 12 is reinforced. Relating to the titled hydrogen detector, a sensor part 11 is directly provided to a fused sodium main flow channel of a fast breeder, and a laser beam source is connected to one end of the fiber 12, and an optical power meter is connected to the other end.
