<p>The method involves immersing an optical fibre in a molten metal bath. Radiation absorbed by the optical fibre in the molten metal bath is fed to a detector, where the optical fibre is heated when immersed in the molten metal bath. The fibre is surrounded by a steel awer, and an intermediate layer is provided between the cover and the optical fibre. Temperature of the optical fibre is allocated to a point of time between two time intervals, where the temperature amounts to a maximum of 600 degree celsius. An independent claim is also included for a device for measuring a parameter of a molten metal bath with an optical fibre.</p> |
