Foresight Fiber Optic Brillouin Distributed Temperature Sensors

• Distributed Fiber Optic Temperature Sensing (B‑DTS) – Uses stimulated Brillouin scattering (BOTDA) to measure temperature continuously along the entire fiber length, turning standard telecom single‑mode fiber into a fully distributed sensor.
• Exceptional Sensing Range – Up to 100 km per Channel – Monitors extremely long assets such as pipelines, power lines, and subsea cables with a single system, reducing the number of units, splice points, and field enclosures required.
• High Spatial Resolution – Down to 1 m – Detects highly localized temperature changes and hot spots over long distances (1 m spatial resolution for up to 20 km, and configurable resolutions up to 20 m), ideal for precise leak, fault, and fire localization.
• High Measurement Precision – ±0.3 °C – Delivers accurate and repeatable temperature profiles for process control, asset integrity monitoring, and early fault detection in demanding industrial environments.
• Fast & Dynamic Measurements – Short acquisition and response times support near real‑time monitoring of rapidly changing temperature events, improving protection in fire detection, well integrity, and power line monitoring applications.
• Multi‑Channel System Architecture – Foresight™ Series supports 2 to 25 channels, enabling simultaneous monitoring of multiple lines, loops, or zones from a single 3U rack‑mountable chassis for scalable coverage.
• Long‑Life, Passive Sensing Infrastructure – Requires no active components along the sensing route; the sensing fiber is completely passive, immune to EMI/RFI, and highly reliable in harsh and remote locations.
• Compatible with Standard Telecom Single‑Mode Fiber – Leverages low‑cost, widely available SMF as the sensing medium, dramatically reducing installation and replacement costs compared to specialized sensor cables.
• Insensitive to Fiber Attenuation Changes & Hydrogen Darkening – Brillouin‑based measurements are largely immune to loss variations and hydrogen‑induced attenuation, critical for downhole, refinery, and high‑temperature industrial environments.
• Flexible Sensor Configurations – Supports loop‑fiber and single‑ended configurations, allowing optimized designs for long linear assets, ring networks, or applications where only one end of the fiber is accessible.
• Extremely Wide Temperature Range – Designed for sensing from cryogenic temperatures (~25 K) up to very high temperatures (up to +2100 °C depending on the sensing cable), covering cryostats, industrial furnaces, refineries, and fire detection.
• Cryogenic Temperature Measurement – Capable of accurate distributed sensing in cryostats and low‑temperature research setups, where conventional electronic sensors are difficult to deploy or unreliable.
• Integrated Temperature, Strain & Pressure Capability – When combined with the appropriate sensing cable and installation, the system can monitor temperature, strain, and pressure along the same fiber for comprehensive structural health monitoring.
• Ideal for Oil & Gas Pipeline and Well Monitoring – Detects leaks, insulation failures, and flow anomalies over tens of kilometers; supports well integrity monitoring from surface to reservoir depth with high spatial resolution and rapid response.
• Refinery Process & Efficiency Optimization – Continuous distributed temperature profiling helps optimize heat exchanges, furnaces, and reactors to improve efficiency, reduce energy consumption, and minimize unplanned downtime.

• Oil and Gas Well Monitoring – Downhole distributed temperature sensing for production and injection wells, including vertical, deviated, and horizontal wells, to monitor inflow profiles, gas breakthrough, and water encroachment.
• Well Integrity Management – Continuous temperature and strain monitoring to identify casing deformation, tubing leaks, annular gas migration, and packer or completion failures.
