Capillary seamless steel tube FBG (Fiber Bragg Grating) sensors represent a significant advancement in structural health monitoring and industrial sensing, particularly in harsh environments. By utilizing a seamless metal tube for encapsulation, these sensors overcome the limitations of traditional adhesive-based packaging.

Technical Advantages of Seamless Steel Tube FBG Sensors

The core advantage of this technology lies in its all-metal encapsulation. Compared to traditional sensors, the OFSCN® capillary seamless steel tube design provides:

1. Elimination of Creep: Since no glue or polymer is used between the FBG and the protective tube, the sensor avoids the measurement drift (creep) typically caused by adhesive aging or high-temperature softening.
2. High Temperature Resistance: Depending on the specific model, these sensors can operate reliably in environments ranging from cryogenic levels up to 300°C, 500°C, or even higher.
3. Mechanical Protection: The seamless steel tube (typically 304 or 316L stainless steel) offers superior protection against lateral pressure, corrosion, and physical impact.
4. Excellent Heat Transfer: The metallic structure ensures rapid thermal response times for temperature sensing applications.
