Optical Fiber Sensors vs. Conventional Electrical Strain Gauges for Infrastructure Monitoring Applications

Public infrastructure, including bridges, pipelines, tunnels, foundations, roadways, dams, etc., is subject to factors that can degrade it or lead to malfunctions. These structural problems can be the result of deterioration, improper construction methods, seismic activity, nearby construction work, etc. Although electrical strain gauges have long been used for monitoring structural changes, they sometimes lack the durability and integrity necessary to provide accurate, actionable information over extended periods. The applications in this white paper demonstrate how optical fiber sensors can offer a variety of economic and performance advantages.

Acrylate-Based Specialty Optical Fiber Coatings for Harsh Environments

Applications of optical fibers at high temperatures and in harsh environments demand coatings sustainable under those conditions. The goal of this work was to evaluate thermal and environmental stability of a series of commercially available and in-house formulated acrylate-based coatings. Dual and single-coat fiber designs were tested. The individual formulations included non-urethane and urethane acrylates, silicone acrylates and an organic-inorganic hybrid acrylate. The “as drawn” fibers were tested for attenuation, mechanical reliability, microbend sensitivity, delamination resistance and coating stripability. Thermogravimetric analysis (TGA) was used for estimating the use temperature of the coatings. In addition, the fibers were exposed to harsh environments, including dry aging in air (150°C) and in nitrogen (250°C), autoclaving, immersion in high pressure/temperature water (up to 200°C and 2000 psi) and immersion in a hot cable gel (160°C). Based on the obtained results, the best formulations were ranked for suitability in different types of fiber application.
