Abstract:

This report describes the cermet sensors and system control software recently evaluated in shipboard tests for shipboard damage control. The tests were conducted to evaluate a database of sensor responses to fire and nuisance sources for algorithm development, and to provide a basis for further refinement. In this work, the cermet sensors incorporate four sensors with multivariate analysis methods and classification algorithms for detecting a wide variety of analytes including toxic industrial chemicals, fires, and nuisance sources. The test series successfully demonstrated the functionality and performance of the microsensor system for use in fire detection. The detection system demonstrated the ability to detect flaming and smoldering fires at the same level as the commercial multicriteria detector. It was on average 2 to 3 minutes faster for flaming fires, vs. all detector types evaluated, and 7.5 to 8.3 minutes faster for smoldering fires, vs. all detector types evaluated. The system needs improvement in addressing fire-like nuisances.
