The FOS-N strain sensor offers small size, high accuracy, immunity to EMI/RFI, and resistance to corrosive environments with a high temperature range.Manufacturers, civil structure designers, and research engineers may now improve structure technology by developing and testing composite materials in a range of applications. The capability to monitor the performance of new materials and structures is crucial to evaluate them objectively. Monitoring specifi c properties over time will help improve the safety and durability of civil structures. The de-
ployment of sensors within a structure, whether it is a bridge or a dam, provides accurate information on changes in strains in the structure. Monitoring stresses in structural members of buildings, bridges, tunnel linings and supports during and after construction is also possible with the FOS-N fi ber optic strain sensor. The use of the FOS-N strain sensor allows a complete stress/strain analysis in the most challenging environments.Based on proven Fabry-Perot interferometer technology, FISOs fi ber optic strain sensors are the best choice for high performance strain measurements. The tech-
nology upon which are based the FOS-N strain sensor and the compatible monitor-
ing system provide absolute strain measurements at very long distances without affecting the reliability of the readings.The FOS-N strain sensor is not sensitive to any pulling or manipulation of the in-coming fi ber. This feature is advantageous when the sensor is embedded into com posite materials.The FOS-N fi ber optic strain sensor withstands harsh chemical environments and offers ruggedness and fl exibility for todayҒs high-performance composite mate-rial research and civil structure monitoring requirements.
