The capillary seamless steel tube encapsulation of the OFSCN® 650°C Distributed Fiber Optic Temperature Sensor is crucial for its endurance against the 650°C extreme temperature and harsh environments. However, industrial users often worry: Will this high-strength steel tube protection make field installation and wiring exceedingly difficult?
The packaging design by [Beijing Dacheng Yongsheng Technology Co., Ltd. (DCYS)] aims to balance extreme mechanical protection with reasonable installation flexibility. This article will analyze the advantages of the steel tube packaging and guide you on overcoming installation challenges to ensure smooth project deployment.
I. Capillary Seamless Steel Tube: Armor Born for Extreme Environments
Our sensor fiber is housed inside a high-strength, seamlessly welded steel tube, providing protection unparalleled by standard fiber optic cables:
- High-Strength Protection: The steel tube effectively resists tension, lateral crushing, and accidental impact during installation, preventing fiber damage during complex wiring.
- Corrosion Resistance: The steel tube material (such as 316L Stainless Steel or specialized high-temperature alloys) resists corrosive media like acidic steam, seawater, and groundwater, ensuring the sensor's long lifespan in chemical, oil & gas, and marine environments.
- Water and Gas Tightness: The seamless structure guarantees excellent sealing performance, preventing moisture, dust, or chemical gases from infiltrating, which could otherwise contaminate the fiber or affect optical performance.
II. Installation Difficulty Analysis: Flexible Wiring and Minimum Bending Radius
Despite the steel tube's robustness, we optimize the capillary tube's size and materials to ensure sufficient flexibility while meeting protection needs:
- Flexible Wiring: The capillary tube design means a small outer diameter, providing a significantly smaller minimum bending radius (refer to the product specification for specific values) compared to bulky armored cables. This allows the sensor to be tightly routed along complex pipelines and equipment contours, adapting to narrow industrial spaces.
- Kink Resistance: The rigid structure of the steel tube effectively prevents the cable from excessive twisting or kinking, which not only protects the internal fiber but also simplifies the long-distance wiring process.
- Fixation and Routing: During wiring, standard industrial clamps, zip ties, or welded fixtures are typically sufficient to securely affix the sensor along the surface of the monitoring target.
III. Field Operation and Termination: Customized Solutions
Field fiber splicing and terminal connection are critical steps for high-reliability sensors. DCYS provides integrated solutions for these needs:
- High-Temperature Splice Protection:
- Traditional splice protection sleeves melt at high temperatures. For 650°C applications, we offer complementary special high-temperature splice protection sleeves or mechanical protection solutions to ensure the splice point remains stable even under high heat.
- Customized Pigtails:
- We provide customized fiber pigtails. In a safe area away from the heat source, the steel tube sensor transitions into a standard high-reliability fiber patch cord for easy connection to the interrogator or junction box.
- Junction Boxes and Feedthrough Flanges:
- For through-wall requirements in high-temperature chambers, we can provide compatible high-temperature feedthrough flanges (e.g., CF/KF flanges) and industrial-grade junction boxes to consolidate and protect the fiber link on-site, simplifying overall system integration.
[Beijing Dacheng Yongsheng Technology Co., Ltd. (DCYS)] is committed to delivering "rock-solid" sensing solutions in extreme environments. Through our optimized capillary seamless steel tube packaging, you do not have to compromise between mechanical protection and installation convenience.
