Distributed Sensing Technology Redefines Industrial Safety
Distributed Fiber Optic Temperature Sensing (DTS) systems leverage Raman scattering optical principles to achieve millimeter-level spatial resolution over 30km measurement ranges. When laser pulses travel through the fiber, the system analyzes backscattered light to detect temperature changes with ±0.5°C accuracy at every 1-meter interval. This continuous monitoring capability proves vital for identifying pipeline hotspots, downhole thermal profiling, and early fire detection in ATEX Zone 2 oil refineries.
5 Competitive Advantages Over Conventional Sensors
1. Explosion-Proof Design: Glass fiber core eliminates spark risks in flammable vapor environments
2. EMI Immunity: Functions reliably near 100kV substations and VFD-driven pumps
3. Corrosion Resistance:
Withstands H2S concentrations up to 500ppm in sour gas wells
4. Cost Efficiency:
Monitors 8km radius with single cable vs 800+ traditional RTD sensors
5. Real-Time Alerts:
Integrates with SCADA systems for instant leak/shutdown triggers
