The goal of this work was to develop, install, and test an ultrasonic instrument for continuous, nondestructive evaluation of TNT mixtures inside a production melt kettle. A first instrument was installed and tested at a pilot-scale melt kettle in building 810 at the U.S. Army Armament Research, Development and Engineering Center, Picatinny Arsenal, NJ. This instrument was then lengthened for installation in a full-sized melt kettle on Line 3a at the Iowa Army Ammunition Plant, Middletown, Iowa operated by American Ordnance. The instrument includes an ultrasonic transmitter and receiver encased in a stainless steel probe, and the electronics to interpret the measured ultrasonic signals. The instrument provides continuous information on the amount of solid TNT in the solidliquid molten TNT mixture in the kettle. This information will be used to improve the quality, safety and costs of manufacturing TNT munitions.
