PORTABLE AXLE WEIGHING SCALE USING OPTICAL FIBER SENSOR AND ITS OPERATING METHOD

摘要

The present invention relates to an axial relay for measuring an axle load, wherein a pair of gutter pipe sensors (12) are symmetrically installed in a main body (10) on which a decompression module (11) with an optical fiber sensor is applied such that a position of an axle can be grasped and a measurement can be performed on the basis of the same. According to the present invention, portability can be maximized by reducing the size and weight of the axial relay main body (10), thereby improving a convenience of installation and use of the axial relay.
