This article analyzes the advantages and application benefits brought by the small size of fiber bagg grating (FBG) sensors, including improved sensitivity, expanded usage environments, and convenience in engineering construction. It also introduces the production of the small-sized "OFSCN® Capillary Seamless Steel Tube Series FBG Sensor" (also known as micro FBG probes or FBG sensors) by DCYS, which can be used for measuring various physical quantities such as temperature, strain, and stress in extreme environments. Partial physical images are provided.

This topic highlights the significant advantages of miniaturized Fiber Bragg Grating (FBG) sensors. In the field of optical fiber sensing, reducing the sensor diameter is not just about saving space; it is a critical technical upgrade for sensitivity and environmental adaptability.
Technical Advantages of Small-Diameter FBG Sensors
- Enhanced Sensitivity: Smaller sensors have lower thermal mass and mechanical stiffness. For temperature sensing, this leads to a faster thermal response time. For strain sensing, a smaller diameter minimizes the “reinforcement effect” on the measured structure, allowing for more accurate data acquisition.
- Seamless Integration: With diameters as small as 0.5mm to 0.6mm, these sensors can be embedded into composite materials, small-diameter tubes, or tight mechanical gaps where traditional sensors cannot fit.
- Mechanical Robustness: By using seamless steel tube packaging, the sensor maintains high protection levels despite its micro size, resisting high pressures and corrosive environments.
