This product is a high-range fiber bragg grating strain sensor (FBG strain gauge) used for strain measurement. It can be used in a single-ended structure, where it is inserted into the object to be measured for strain measurement. It can also be used in a double-ended structure, where it is fixed with a fixture or bonded directly to the surface for strain measurement, enabling multi-point strain measurement when connected in series. The structure of this product is the same as that of fiber bragg grating stress sensors.

The information provided describes the OFSCN® Polymer-encapsulated Fiber Bragg Grating Strain Sensor (1.5mm/2.3mm diameter). This sensor is designed for high-range strain measurement and is versatile enough for insertion, immersion, or surface-mount applications.
Technical Overview
Based on the technical specifications for this product line:
- Measurement Range: Up to 6000με (microstrain).
- Structure: Available in both single-ended (for insertion/immersion) and double-ended configurations (for series connection and multi-point sensing).
- Encapsulation: It features a specialized polymer encapsulation that provides moisture resistance and protection, maintaining a slim profile (1.5mm or 2.3mm diameter).
- Compatibility: The internal structure is consistent with FBG stress sensors, allowing for precise strain-to-stress calculations if the elastic modulus of the measured material is known.

Key Features
- Multi-point Multiplexing: Multiple sensors can be integrated into a single fiber string, which is ideal for distributed strain monitoring along a structure.
- Environmental Resistance: The encapsulation is designed to handle harsh environments while remaining EMI (Electromagnetic Interference) immune.
- Customization: Parameters such as fiber length, connector type (FC/APC, etc.), and the number of sensing points can be customized to specific project requirements.
