An integrated probefluidic temperature sensor designed by the Air Force Aero Propulsion Laboratory was fabricated from iridiumrhodium noble metal alloy. Two fluidic sensors fabricated from iridiumrhodium were successfully calibrated from 1000 to 3000F at 4 and 6 atmospheres. Transient response tests conducted at 4 atmospheres showed that the integrated probefluidic sensor responded much faster to step temperature changes than burner rig thermocouples but was slower than the thermocouples in reaching a stabilization temperature. One fluidic sensor was operated at 3000F for one hour without any deviation from its calibration frequency. Author
