17 December 1980 Infrared Pyrometers For Measuring Dust Explosion Temperatures
Author Affiliations +
This paper will describe the design of two infrared optical pyrometers used to study dust explosions. One is a six-wavelength pyrometer that can measure both dust particle temperature and gas temperature by observing continuum and gas band emission in the 1 to 5 μm infrared region using PbSe detectors. The second pyrometer measures particle continuum emission in the 0.8 to 1.0 μm region of the near infrared using Si detectors. Temperature data are presented for both laboratory and full-scale mine explosions.
