    摘要: A method is provided for measuring a temperature of a molten metal bath by an optical fiber surrounded by a cover. The optical fiber is immersed in the molten bath, and the radiation absorbed by the optical fiber in the molten bath is fed to a detector, wherein the optical fiber is heated when immersed in the molten bath. The heating curve of the optical fiber has at least one point P(t0, T0), wherein the increase ΔT1 in the temperature T of the optical fiber over the time Δt in a first time interval t0−Δt up to the temperature T0 is smaller than the increase ΔT2 in the temperature of the optical fiber over the time Δt in an immediately following second time interval t0+Δt.
