The OFSCN® Fiber Bragg Grating (FBG) Strain Gauge is a high-performance, high-precision fiber optic sensing product specifically designed for highly reliable strain and stress monitoring in structures, Strain gauge lengths of 3.6 cm, 7.2 cm, and 10.8 cm are available. This product features a unique I-beam encapsulation structure to efficiently achieve both strain measurement and temperature compensation. Key advantages include immunity to electromagnetic interference (EMI), corrosion resistance, and easy multi-point cascading, making it ideal for long-term Structural Health Monitoring (SHM) in civil engineering, aerospace, and rail transportation.

Thank you for the detailed information regarding the OFSCN® Fiber Bragg Grating (FBG) Strain Gauge.
As a supplement to the technical specifications provided, it is important to note that these strain gauges are specifically engineered to cover shorter measurement lengths (3.6 cm, 7.2 cm, and 10.8 cm) that are typically difficult to address with standard tubular packaging.
Key Technical Characteristics:
- Encapsulation Structure: Uses an I-beam stainless steel or aluminum alloy sheet for single-point FBG encapsulation.
- Installation Methods: Primarily supports adhesive surface bonding or four-corner spot welding, providing flexibility for different structural materials.
- Measurement Range: Default strain range is ≥10,000 με, with a linear calibration formula provided in με/pm.
- Electromagnetic Immunity: Like all OFSCN® FBG sensors, these are completely immune to EMI, making them superior to traditional electronic strain gauges in high-interference environments.
