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 and comprises a pair of side sensors 12 mounted symmetrically on a main body 10 on which a pressure sensitive module 11 to which an optical fiber sensor is applied is installed So that the position of the axle can be grasped and the measurement can be performed based on the position of the axle. The present invention can maximize the portability by reducing the size and weight of the shaft relay main body 10, thereby improving the installation convenience and utilization of the shaft relay.
