High-Temperature Temperature Measurement Optical Cable System in North Macedonia

Fiber optic temperature measurement systems provide precise, distributed, and high-resolution temperature monitoring for harsh and high-temperature environments, with local availability in North Macedonia through suppliers like KROHNE and international providers such as Yokogawa and Luna.

Overview of Fiber Optic High-Temperature Measurement

Fiber optic temperature sensors are increasingly used for high-temperature applications above 1000 °C, such as in aerospace, metallurgy, power generation, and industrial process monitoring, due to their resistance to electromagnetic interference, small size, and ability to perform distributed measurements over long distances . Unlike traditional thermocouples or RTDs, the optical fiber itself acts as the sensing element, enabling continuous temperature profiling along pipelines, storage tanks, or combustion chambers .

Key Advantages

• Distributed sensing: Thousands of temperature points along a single fiber, up to 50 km for systems like Yokogawa DTSX3000 .
• High spatial resolution: Sub-millimeter resolution achievable with Rayleigh backscatter-based systems .
• Harsh environment tolerance: Immune to electromagnetic noise, high pressures, and extreme temperatures .
• Multipoint and multiplexing capability: Multiple sensors can be integrated on a single fiber, reducing wiring complexity .

Technologies and Systems

1. Distributed Temperature Sensing (DTS)

   • Uses Raman scattering to measure temperature along the fiber length.
   • Example: Yokogawa DTSX3000, suitable for long-distance pipelines, power cables, and large industrial facilities .

2. Fiber Bragg Grating (FBG) Sensors

   • Provide multipoint temperature and strain measurements.
   • Can be embedded in structures or installed in locations inaccessible to traditional sensors .

3. High-Definition Distributed Sensing

   • Systems like ODISI and OptaSense QuantX offer high-fidelity, long-range temperature monitoring with sub-millimeter spatial resolution .

4. Point Fiber Optic Sensors

   • Include fiber optic probes with temperature converters for precise measurements over a wide temperature range .
