Abstract :
A sensor design is presented based on waveguides of the order of 1 mm in diameter and 1 meter in length for the application of high temperature process monitoring. The critical issues of temperature dependence of the acoustic waveguide is discussed. Insertion loss data are presented on several waveguide systems for comparison
