Abstract: PURPOSE:To enable an input characteristic to be easily uniformed by oppositely arranging two sensors comprised of detecting coils wound around magnetic cores on both sides of a conductor wherein a current to be measured flows so that distances between the two sensors and the conductor can be changed. CONSTITUTION:A sensor casing 5 is made of a resin and sensors 3a and 3b comprised of detecting coils 2a and 2b wound around amorphous magnetic cores 1a and 1b inserted in the central portions of the sensors 3a and 3b, respectively, on both sides thereof, said sensors being fixed by a resin. The coils 2a and 2b are led to a module portion 6 mounted to the lower side of the casing 5. A conductor 4a is inserted into the groove of the casing 5 and connected thereto.

Abstract: PURPOSE:To make the measuring distance long and to make it possible to perform highly accurate measurement by utilizing the relationship between the spectral width of Brillouin gain and temperature in the Brillouin scattering phenomenon generated in an optical fiber. CONSTITUTION:First signal light S1 from a first light source 1 is coupled into an optical fiber 3 to be measured through a multiplexing/splitting device 4. Meanwhile, second signal light S2 from a second light source 2 is coupled into the optical fiber to be measured 3 through a terminal 3-2 which is opposite to a terminal 3-1 of the fiber 3. The relative frequency difference  f between the light frequency f1 of the light S1 which generates Brillouin phenomenon and the light frequency f2 of the light S2 is continuously or discretely changed. The intensity of the light S2 is observed by using a photodetector 5. The spectrum of the Brillouin gain is obtained based on the relationship between the intensity of the amplified light and  f. The spectral width of the Brillouin gain is linearly changed with the temperature. The highly accurate temperature measurement can be performed, and the long-distance measurement can be performed with the single-mode light characterized by a large amount of attenuation.
