Integrated European research, calibration and testing infrastructure for fibre-optic thermometry

Fibre-optic temperature measurement is particularly well suited for use in environments with high temperatures or strong electrical interference, such as factories and power plants. It can also provide temperature readings at multiple points along the length of the fibre.

However, the technology faces certain challenges. It may be affected by vibration, humidity, or ageing of materials. Researchers therefore need to determine how to make these measurements more accurate and reliable.

The project has four main components:

1. Research – Determine how accurate fibre-optic thermometers are, and how they are affected by environmental factors such as humidity, vibration and ageing.
2. Development – Create improved measurement methods for high temperatures (up to 1600 °C).
3. Testing – Test the technology in real industrial environments, such as solar cell production and power grids.
4. Training and guidance – Develop courses, guides and calibration services for users of the technology.

The Norwegian Metrology Service (JV) participates as an internal partner, contributing expertise in traceability. NORCE participates as an external partner and work-package leader, while Statnett and Elkem contribute by testing the technology in real industrial environments.

The project is funded by the European Union through the Partnership on Metrology, coordinated by EURAMET, and will be completed in September 2026.
