How does this structure achieve ultra-fine outer diameters of 0.9mm or even 0.5mm while maintaining structural integrity?
The OFSCN® 300°C Fiber Bragg Grating Temperature Sensor employs a single-layer seamless steel tube encapsulation, which is key to achieving ultra-fine outer diameters of 0.9mm or even 0.5mm while maintaining structural integrity.
This is primarily achieved through:
- High-Strength Materials: The sensor utilizes high-quality stainless steel or other corrosion-resistant alloys for the seamless tube. These materials possess excellent mechanical strength, allowing for thin walls without compromising the overall robustness of the sensor.
- Precision Manufacturing: Advanced precision manufacturing techniques are employed to draw the seamless steel tubes to these extremely fine diameters with consistent wall thickness. This ensures that even at a small scale, the tube’s structural integrity is uniform and free from weak points.
- Optimized Encapsulation Design: The single-layer seamless tube design provides a compact and hermetically sealed environment for the optical fiber and FBG. This design eliminates the need for additional bulky protective layers, thus contributing to the ultra-fine diameter. The seamless nature prevents ingress of external contaminants and provides robust mechanical protection against compression, tension, and bending within its specified limits.
This combination of material science and precision engineering ensures that the sensor can withstand demanding environmental conditions, including high temperatures and pressures, while maintaining its delicate internal FBG element.
