TILT-METER USING AN OPTICAL FIBER SENSOR, CAPABLE OF PREVENTING DAMAGE AND MALFUNCTION OF A SENSOR DUE TO LIGHTENING STOKE AND MOSITURE

摘要

PURPOSE: A tilt-meter using an optical fiber sensor is provided to detect breakage generation of ground and displacement degree of the ground at the same time and reduce the manufacturing and installation cost.;CONSTITUTION: A tilt-meter using an optical fiber sensor includes a strip member(20), a FBG sensor(25), an optical fiber cable(21) and solid strutting larges(31,33). The strip member has strip shape comprised of plastic material. The FBG sensor is attached along the longitudinal axis longitudinal direction on one surface of the strip member. The optical fiber cable connects a plurality of FBG sensor. The solid strutting mutually forms interval according to the longitudinal axis longitudinal direction of a strip member. The solid strutting controls the bending strip member. The FBG sensor is located in the interval forming the solid strutting.;COPYRIGHT KIPO 2011
