Fiber Optic Strain Sensor 'Regarding Bridge Instrumentation'

Application note on bridge instrumentation due to environmental changes and heavy loads during vehicle passage.

Fiber optic strain sensors are compact, high-precision devices capable of measuring strain in high-temperature environments. They are designed to be unaffected by EMI/RFI interference and can operate in highly corrosive environments, utilizing the latest technology. The Joffre Bridge in Seabrook was reconstructed in 1997 to demonstrate the feasibility of remote monitoring using fiber optic sensors, reinforcement of the bridge with FRP, and the use of fiber optic sensors. As a result, the deflection of the bridge's superstructure and the response to FP reinforcement fell within acceptable limits, and the bridge's condition is now being monitored over an extended period using a system capable of collecting data from 32 channels of fiber sensors. This application example has proven that Fabry-Perot fiber optic sensors are suitable for both short-term and long-term monitoring of bridge conditions. 【Features】 - Measurement of environmental changes and behavior due to heavy loads from vehicle traffic on FRP-reinforced bridges - Proven suitability for monitoring bridge conditions - Currently active in various fields, etc. *For more details, please refer to the catalog or feel free to contact us.
