Abstract

A novel thin-filament pyrometer is presented. It involves a consumer-grade color digital still camera with 6 megapixels and 12 bits per color plane. SiC fibers were used and scanning-electron microscopy found them to be uniform with diameters of 13.9   μm . Measurements were performed in a methane–air coflowing laminar jet diffusion flame with a luminosity length of 72   mm . Calibration of the pyrometer was accomplished with B-type thermocouples. The pyrometry measurements yielded gas temperatures in the range of 1400–2200 K with an estimated uncertainty of ± 60   K , a relative temperature resolution of ± 0.215   K , a spatial resolution of 42   μm , and a temporal resolution of 0.66   ms . Fiber aging for 10 min had no effect on the results. Soot deposition was less problematic for the pyrometer than for the thermocouple.
