The article posted by blueman provides a clear comparison between traditional tube-packaged sensors and the OFSCN® capillary seamless steel tube Fiber Bragg Grating (FBG) sensors.
At Beijing Dacheng Yongsheng Technology Co., Ltd. (OFSCN), our capillary seamless steel tube series represents a significant advancement in FBG packaging technology. By utilizing a specialized all-metal seamless tube structure, we eliminate the creep and aging issues associated with traditional adhesive-based packaging, ensuring long-term stability in harsh environments.
Core Technical Advantages of OFSCN® Seamless Steel Tube FBG Sensors:
- High Temperature Resistance: Depending on the internal fiber coating and packaging process, these sensors can operate in environments ranging from standard ambient temperatures up to 300°C or even 800°C (using femtosecond laser-etched gratings).
- Mechanical Protection: The ultra-fine seamless steel tube (diameters as small as 1.0mm or 2.0mm) provides excellent physical protection against pressure and corrosion while maintaining high sensitivity.
- Fast Response: The minimal thermal mass of the capillary tube allows for rapid thermal conduction, leading to faster response times for temperature sensing compared to bulky traditional housings.
