Optimal FBG Sensor Installation Process for Crane SHM System

Abstract:

In order to improve the accuracy of measurement results, we should do our best to reduce the optical loss while welding FBG Sensors and adopt appropriate bonding technology. Taking simple tools and suitable approach can also achieve good result. We take three steps while welding FBG sensors, the steps are manufacture end face, welding, and heat shrinkable. Manufacturing end face of a fiber is the key step among them. It is important to adopt the sequence diagonal welding method and use a damp cloth to cool the other parts of the sensor while welding which can increase the accuracy of measurement. Use pen-made red light to check the fiber joints.
