GFRP Fiber Bragg Grating Strain Gage︱TVS-S-3510
▪ Suitable for strain monitoring on surfaces of bridges, gas pipelines, etc
▪ Large steel structures: steel rails, transmission line towers, cranes, cranes
▪ Strain monitoring inside materials
Description
TVS-S-3510 is a small, high-sensitivity GFRP(Glass-Fiber-Reinforced Plastic) cable sensor. Designed for monitoring surface or embedded strain and temperature. At its core, the TVS-S-3510 sensor consists of a single fiber with a Bragg grating (FBG) sensor inside and Glass-Fiber-Reinforced Plastic (GFRP) coating on the outer layer to protect the FBG sensor and reinforcing the overall structure of the sensor. With many of the inherent advantages of FBG-based sensors, small size, serial connection, resistance to electromagnetic interference, while making up for the weak weakness of the bare grating itself, improve the robustness to meet the needs of the engineering site.
Key Features
▪ High precision, high resolution, measurable positive and negative strains
▪ Not affected by electromagnetic interference, it has good natural explosion-proof, temperature resistance, corrosion resistance, and aging resistance
▪ Can be measured in series, making it easy to build a distributed sensing network
▪ GFRP material packaging,
▪ Small size, easy installation, and reusable
