Room Temperature Acoustic Transducers for High-Temperature Thermometry



Dean C. Ripple, William E. Murdock, Gregory F. Strouse, Keith A. Gillis, Michael R. Moldover


We have successfully conducted highly-accurate, primary acoustic thermometry at 600 K using a sound source and a sound detector at room temperature. We describe the source, the detector, and the ducts that connected them to our cavity resonator. This transducer system preserved the purity of the thermometric gas, generated small, predictable perturbations to the acoustic resonance frequencies, and can be used at much higher temperatures.
