So wählen Sie den besten faseroptischen Temperatursensor für Öl aus & Gasanwendungen?-INNO

Distributed Sensing Technology Redefines Industrial Safety

Verteilte faseroptische Temperaturmessung (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 Genauigkeit 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.
