ABSTRACT:
Light emitting diodes (LED) are used in conjunction with phototransistors determine the liquid-solid state of a 0.030-0.040 inch film of trinitrotoluene (TNT). Liquid TNT is collected on the surface of a rotating drum, and is subsequently cooled to a solid film and removed by a "flaking" knife. The emitted beam from the LED is absorbed when the TNT is in the solid state and transmitted to and reflected from the drum surface when the TNT is in the liquid state. The relative intensity of the reflected beam is a measure of the state of the TNT.
