Page Content

Fiber optic cables can be used for high-resolution temperature measurement in Denmark, with local suppliers and advanced distributed sensing technologies available.

Technology Overview

Fiber optic temperature measurement uses the optical fiber itself as the sensing element, allowing continuous temperature monitoring along the cable length. Modern methods, such as Distributed Temperature Sensing (DTS), rely on Raman or Rayleigh backscattering to determine temperature profiles with high spatial resolution and accuracy . For example, DTS systems can measure temperatures over distances up to 60 km, with accuracy better than 0.1°C and spatial resolution around 0.7 meters for shorter cables . These systems are ideal for applications like leak detection, fire monitoring, and structural health monitoring.

Two common measurement approaches are used:

  • Gradient Method: Detects temperature changes when the environment and target medium have different temperatures.
  • Heat Pulse Method (HPM): Used when temperature differences are small or constant, such as in water bodies or closely spaced installations .

Fiber optic sensors are also immune to electromagnetic interference, making them suitable for harsh industrial environments . Multipoint sensing using fiber Bragg gratings (FBGs) allows distributed or multiplexed measurements over large areas .

Suppliers and Availability in Denmark

Several companies provide fiber optic cables and temperature sensing solutions in Denmark:

  • Farnell Denmark: Offers a wide range of fiber optic cables suitable for high-speed data and sensing applications, including single-mode and multimode options .
  • FiberMAN: Specializes in fiber optic installations and network solutions, including offshore and industrial applications .
  • NKT: Global supplier of high-end cables, including fiber optic solutions for industrial and infrastructure projects .
  • Yokogawa DTSX200: Distributed temperature sensing systems available for long-distance, high-resolution temperature monitoring .
  • Luna Technologies: Provides high-definition fiber optic temperature and strain sensing systems for harsh environments and precise monitoring .

Applications in Denmark

Fiber optic temperature measurement is widely applicable in Denmark for:

  • Industrial plants: Monitoring furnaces, pipelines, and chemical processes.
  • Environmental monitoring: Detecting leaks or temperature changes in soil, water, or infrastructure.
  • Energy sector: Offshore wind farms, power plants, and battery monitoring.
  • Construction and civil engineering: Embedded sensors in concrete or structural elements for long-term monitoring .

Conclusion

For temperature measurement in Denmark, fiber optic cables combined with DTS or FBG-based systems provide precise, distributed, and reliable monitoring over long distances. Local suppliers like Farnell, FiberMAN, and NKT can provide the necessary cables and installation support, while specialized systems from Yokogawa and Luna offer advanced sensing capabilities for industrial and environmental applications.
