Infrared Pyrometers for Measuring Dust Explosion Temperatures.
Modern Utilization of Infrared Technol VI,Spie 1980 253:7 pages
This paper describes 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-um infrared region using pbse detectors. The second pyrometer measures particle continuum emission in the 0.8- to 1.0-Um region of the near infrared using si detectors. Temperature data are presented for both laboratory- and full-scale mine explosions.
