DTS (Distributed Temperature Sensing) Fibre Systems
Distributed Temperature Sensing (DTS) systems are technologies capable of temperature monitoring over long distances using fibre optic cables. DTS systems are used for fire safety and industrial process control, especially in large and challenging areas. These systems precisely detect and monitor temperature variations at any point in the fibre optic cable. DTS fibre systems are widely used in various industries such as energy, petrochemical, transportation and construction
Working Principle of DTS Fiber Systems;
DTS (Distributed Temperature Sensing) fiber systems provide temperature information by analyzing the propagation and backscatter of laser light through optical fiber cables. The main components of these systems include:
Optical Fiber Cable: The core component of the DTS system, the optical fiber cable, detects temperature variations over long distances.
Laser Source: It sends a laser beam through the optical fiber cable.
Receiver and Analysis Unit: It analyzes the light reflected back from the optical fiber cable, collects temperature data, and processes it.
DTS systems measure temperature using Rayleigh, Raman, and Brillouin backscatter techniques. These techniques are sensitive to temperature variations along the optical fiber cable and provide precise temperature information at any point along the cable.
Advantages of DTS Fiber Systems
DTS fiber systems offer several advantages, making this technology applicable across a wide range of industries:
Long-Distance Monitoring: DTS systems can monitor temperatures over distances of 30 km or more using a single optical fiber cable.
High Sensitivity: Optical fiber cables can detect temperature changes with millikelvin sensitivity.
Durability and Reliability: Optical fiber cables are resistant to harsh environmental conditions and immune to electromagnetic interference.
Multi-Point Monitoring: DTS systems can monitor temperature changes at any point along the optical fiber cable, enabling multi-point temperature monitoring.
Low Maintenance Requirements: Compared to traditional temperature sensors, DTS systems require less maintenance and have a long lifespan.
Applications of DTS Fiber Systems;
DTS fiber systems are used in various industries for different purposes. Common application areas include:
Energy Sector: Used for monitoring the temperature of oil and gas pipelines, power cables, and power generation facilities.
Petrochemical Plants: Ideal for controlling chemical reactions and monitoring the temperature of storage tanks
Transportation: Used for monitoring the temperature of transportation infrastructure such as railway tracks, tunnels, and bridges.
Construction: Used for monitoring the temperature and structural health of large structures, tunnels, and dams.
Fire Safety: Used for early detection of fire risks in warehouses, cable galleries, and large areas.
