Abstract
An apparatus (100) comprises at least one optical cable (104), a detector (106) and a processing unit (108). An end of an optical cable (104) is placed inside the electric arc furnace (10) for collecting light from the furnace (10). The optical cable (104) conveys the light to the detector (106). The detector (106) separates the light into a plurality of optical bands of the spectrum and transforms strengths of the plurality of optical bands into electrical data. The processing unit (108) measures, for determining a state of the furnace (10), a background of the optical bands in a predetermined manner, at least one characteristic strength level of the optical bands and an average deviation of the strengths of the optical bands from the background on the basis of the electrical data.
