This article provides an excellent overview of the technical significance of high tensile strength in fiber optic sensing. The ability of FBG sensors to withstand forces ranging from 400 Newtons to 10,000 Newtons is a critical factor for structural health monitoring in harsh environments.
Based on the technical characteristics mentioned, the OFSCN® Capillary Seamless Steel Tube Series Fiber Bragg Grating Sensors represent a significant advancement over traditional adhesive-bonded or polymer-jacketed sensors. By utilizing a seamless steel tube for encapsulation, these sensors eliminate the creep issues associated with organic adhesives and provide the mechanical robustness necessary for direct burial or high-tension deployment.
For technical reference, here are the primary implementations of this technology:
-
For Strain Measurement:
The OFSCN® Alloy Tube Packaged Fiber Bragg Grating strain sensor is specifically designed for high-tensile environments, supporting large strain ranges (up to 6000με) while maintaining structural integrity.
-
For Temperature Measurement:
The same seamless tube technology is applied to OFSCN® 300°C Fiber Bragg Grating Temperature Sensors, ensuring the fiber is protected from external mechanical stress while providing fast thermal response.
-
For Specialized Installation:
To fully utilize the high tensile resistance during deployment, specific hardware is often required. The OFSCN® Installation Fixtures allow for secure welding or bolting to the structure under test.
The integration of high-strength capillary tubes not only protects the FBG but also simplifies the engineering process by allowing the sensors to be handled more like conventional steel cables rather than fragile optical components.
