THERMIONIC TEMPERATURE TRANSDUCER
Abstract
The purpose of this program was to prove the feasibility of using thermionic emission techniques for the transduction of elevated temperatures (above 2000 F). Several techniques were investigated, as were possible emitter materials and corrosion-resistant coatings. Three transducer designs were developed. The range over which tungsten, the most satisfactory emitter material, could be expected to exhibit repeatable temperature indications was beyond the long-lifetime capabilities of the corrosion-resistant coatings. Since the designs developed were also marginal as temperature transducers, the recommendation was made that the program be terminated at the end of the study phase. Construction of the temperature transducers would not advance the state of the art of high temperature measurement. The program did not consider the suitability of thermionic techniques at temperatures under 2000 F.
