광섬유 온도 측정 시스템을 선택하는 방법: Key Specs Compared-INNO

When selecting fluorescent fiber optic temperature measurement systems, focus on these 5 key specifications:
1️⃣ Temperature Range (-200°C ~ +300°C) – Determines suitability for extreme environments like cryogenics or high-voltage substations
2️⃣ Accuracy (±0.5°C(통상)) – Enabled by measuring fluorescent material’s decay time (빛의 세기가 아닌), eliminating LED drift errors
3️⃣ Response Time (<1 비서) – Critical for real-time monitoring in power transformer hotspots
4️⃣ Fiber Type (POF/Glass) – Plastic Optical Fiber (POF) offers flexibility for industrial machinery, while glass fibers suit high-temperature zones
5️⃣ EMI Immunity – 전자 센서와 달리, fluorescence-based systems ignore electromagnetic interference in substations

Pro Tip: Prioritize systems with ATEX/IECEx certifications for explosive environments.

응답 시간 요구 사항

기술	Typical Response	최고의 대상
형광등	0.2-2 초	Process control with moderate dynamics
DTS	5-30 seconds/km	Slow-evolving thermal events
FBG	<10 밀리초	High-speed transient monitoring

Application-Driven Selection

Precision-Critical ScenariosMedical sterilization and semiconductor fabrication demand fluorescent systems’ sub-degree accuracy, where measurement certainty outweighs speed considerations.
Large-Scale MonitoringDTS becomes indispensable for linear assets like pipelines or tunnels, trading absolute precision for unparalleled spatial coverage.
High-Speed DynamicsFBG dominates in aerospace testing and power grid fault detection, where millisecond-level thermal transients require immediate capture.

Implementation Trade-offs

While fluorescent technology excels in hazardous environments, its fiber length limitations (<200중) make DTS preferable for kilometer-scale deployments. FBG’s multiplexing capability proves superior in dense sensor networks, though temperature-strain cross-sensitivity requires advanced compensation algorithms.
