ANGULAR SENSOR FOR MEASURING DISPLACEMENT USING AN OPTICAL FIBER LATTICE SENSOR, CAPABLE OF PRECISELY MEASURING DISPLACEMENT WITHOUT SHAKING WHILE A WEIGHT MEMBER PERFORMS A PENDULAR MOVEMENT BY THE INERTIA

摘要

PURPOSE: An angular sensor for measuring displacement using an optical fiber lattice sensor is provided to regulate an amplitude regulating hole in the outside of a body when transferring an angular sensor for measuring displacement to a site, thereby holding a weight member performing a pendular movement through an amplitude controlling fixing hole and the amplitude regulating hole.;CONSTITUTION: An angular sensor for measuring displacement using an optical fiber lattice sensor(100) comprises a body(600), a fixing body(210), a rotary body(200), an optical fiber(110), and a weight member(400). The body is installed in an object to be measured, thereby constituting a case. The fixing body is installed to be fixed on an inner front surface of the body. The rotary body is installed by being spaced from the fixing body at a predetermined distance. The rotary body is installed in the inside of the body to be rotatable by joining with a bearing. The optical fiber is bonded and connected to the outer circumference of the rotary body and the fixing body while maintaining a tensed state. The weight member is connected to the lower part of the rotary body with a supporter of a predetermined length.;COPYRIGHT KIPO 2013
