An experimental evaluation of a dual-element transducer for measuring gas stream temperatures is described. Temperatures are inferred from simultaneous temperature-time measurements of two elements of identical geometry but unequal thermal capacity. The major effort was devoted to measurements in medium-temperature streams to prove the feasibility of the method. The accuracy of the results was within ±6 percent for measurements from 1950 to 2250 deg F, which was the best experimental accuracy predicted by an earlier analysis of the concept. A limited number of measurements were made in an oxyacetylene flame. The indicated flame temperatures were 4700 and 4789 deg F which agree within 5 percent with measurements made by sodium-line-reversal techniques for equivalent combustion conditions. A gas-stream temperature profile measurement is also presented.
