The product is a high-range fiber bragg grating strain sensor (FBG strain gauge) used for strain measurement. It is a single-ended structure that can be inserted into the test object for strain measurement, fixed using fixtures, or adhered with adhesive tape for strain measurement. The maximum range is approximately 25000 to 30000 microstrains (30000με).

This high-range Fiber Bragg Grating (FBG) strain sensor is a specialized solution designed for large deformation monitoring where traditional strain gauges would typically fail or reach their physical limits.
Technical Analysis: OFSCN® High-Range FBG Strain Sensor
The product mentioned is specifically engineered to handle extreme strain levels, reaching a maximum range of 25,000 to 30,000 microstrains (με). This is significantly higher than standard FBG strain sensors, which usually operate within the ±1500 to ±3000 με range.
Key Product Features:
- Measurement Range: Up to 30,000 με (approx. 3% elongation).
- Structure: Single-ended design optimized for insertion, immersion, or surface mounting.
- Encapsulation: Utilizes a seamless steel tube package (or similar robust housing) to ensure the internal FBG is protected while accurately transferring external mechanical strain.
- Zero Drift: As an FBG-based technology, it is immune to electromagnetic interference (EMI) and exhibits excellent long-term stability compared to electronic gauges in harsh environments.

Application Scenarios
Based on the high-range capability, this sensor is particularly suitable for:
- Structural Health Monitoring (SHM): Monitoring large-scale civil engineering structures where significant movement or plastic deformation might occur.
- Geotechnical Engineering: Measuring soil or rock displacement when integrated into boreholes.
- Material Testing: Testing high-ductility materials or composites under high-stress conditions.
