ATLANTA, Sept. 14, 2016 — Technica Optical Components LLC has announced sensing cables for glass fiber reinforced polymer-fiber Bragg gratings (GFRP-FBG) fibers. For applications where a larger surface area of contact is needed for increased bonding strength and enhanced positioning, the T-120 sensing cable offers a ribbon geometry. The ribbon can contain multiple fibers, with three fibers in the current design. While typically embedded in composite structures and concrete, the sensing ribbon is also well-suited for surface-mounted applications such as pipelines, boilers, storage tanks and vessels, where high sensitivity, high bonding strength and sensor bending are necessary. Furthermore, surface shape monitoring with controlled fiber polarization is also applicable. The rugged T-130 and T-120 sensing cables are typically used in applications where cable integrity must be maintained despite installation challenges such as the need to embed them in composite structures, roads, aircraft runway asphalt and concrete. The cables are also suited for surface-mount applications where high sensitivity is required such as security intrusion detection systems, tunnels, power cables and various geotechnical applications. T130 cable sensors are typically packaged in spools ready for field deployment. For monitoring temperature in harsh environments, the armored T-140 high tensile strength temperature cable sensor is designed to meet demanding applications. In addition to the GFRP coating, which protects the FBG sensors and strengthens the inner construction of the cable, the cable’s final layer is the extremely rugged armored structure. The T-140’s high cable tensile strength and matching tensile modulus is ideally suited for demanding applications where cable integrity must be maintained despite installation challenges that include deployment of long cables and the laying of cables over uneven and rough surfaces.
