Beschreibung
Zusammenfassung:	The present invention concerns a method and an apparatus (12) for measuring the temperature of a fluid stream (11), said apparatus comprising a movable frame (13, 14) having first end facing towards the fluid stream to be measured and an oppositely directed second end; a beam splitter (9) which is movably arranged in the frame for advancement into said fluid stream to open the fluid stream; an optical temperature measurement device (8) for determining the temperature of the fluid stream by measuring the thermal radiation from the fluid stream; and control means for controlling the movement of the frame and the beam splitter and controlling the performance of the optical temperature measurement device.
