Why does Distributed Temperature Sensing (DTS) also require seamless steel tube packaging technology?
Distributed Temperature Sensing (DTS) technology often requires seamless steel tube packaging due to the demanding environments in which it operates.
Reasons for Seamless Steel Tube Packaging in DTS:
- Harsh Environment Protection: Seamless steel tubes provide robust protection for the optical fiber against mechanical stress (crushing, bending), chemical corrosion, and high-pressure conditions commonly found in industrial settings, geological monitoring, or downhole applications.
- High Temperature Resistance: For DTS systems operating in elevated temperatures, specialized seamless steel tube cables with high-temperature resistant optical fibers (e.g., polyimide or gold-coated fibers) ensure the sensor’s long-term stability and accuracy, preventing degradation of the fiber coating and core.
- Enhanced Reliability and Longevity: The hermetic sealing offered by the seamless steel tube prevents moisture ingress, which can significantly degrade fiber performance over time, especially in humid or submerged environments. This extends the lifespan and reliability of the distributed sensing system.
- Compatibility with Distributed Sensing Principles: These cables are specifically designed to function as distributed fiber optic sensing cables, compatible with sensing equipment based on Raman scattering, Rayleigh scattering, or Brillouin scattering principles, which are fundamental to DTS.
For example, OFSCN® 300°C Seamless Steel Tube Fiber Cable is designed for such applications, offering protection in environments up to 300°C with 316L stainless steel or 825 alloy encapsulation.
