Rev Sci Instrum 1982 Mar; 53(3):311-313
An improved optical probe was developed to monitor dust-cloud concentration in explosions even in the presence of dust flame radiation. Principal features of the probe include a pulsed light- emitting diode and a photodetector with optical interference filter to reduce flame radiation. The probe has a u-shaped configuration and air jets to keep the windows dust free. Experimental data are presented for a coal dust explosion.
