Abstract

A method for the contactless measuring of the temperature of objects with a hanging proportion of differently emitting surfaces having the same temperature by means of a multi-channel pyrometer, for example, for pyrometric measurements, on which there are different amounts of residues of the material to be processed. The spectral signal voltages U.sub.ij are ascertained as a function of the difference U.sub.oj -U.sub.uj for the i=1 to m surfaces of the object differing in emissivity, at least m spectral signal voltages U.sub.j are measured and the object temperature is determined from the additive superimposition of the m radiation sources in the measurement location.
