Abstract
We have developed a multichannel fiber-optic based radiation pyrometer for monitoring the temperature distribution across a moving web up to 4 meters wide. The system employs an array of up to 160 pick-ups whose outputs are delivered by optical fibers to the monitor where they are optically multiplexed onto a 16-channel germanium photodiode array. The pick-ups are deployed linearly across the web on 2.5 cm centers. A 32-channel prototype system achieved a noise limited precision of +/- 1 degree(s)C over the range 140 degree(s)C to 200 degree(s)C. The noise increased to +/- 5 degree(s)C at 100 degree(s)C.
