Abstract:

Flueric bridge sensors have been developed for the Air Force as candidate sensors for measuring gas concentrations and temperatures in life support systems aboard aircraft. Three manifold assemblies -- each containing two flueric concentration sensors and one flueric temperature sensor -- were designed, built, and laboratory tested. In addition, equations describing the theoretical performance of both types of sensors were derived. Measured resistive coefficients for all bridge elements show very little nonideal effects for flows below 3.5 cu cmsec. For one of the concentration sensors, known mixtures of carbon dioxide in nitrogen were measured the results were in complete agreement with the theoretical predictions. No temperature-sensing data were gathered in this program. Author
