The design and the calibration of 2 mm and 3 mm O.D. shielded thermocouple total temperature probes are described. The 3 mm O.D. probe recovery factor is 0.985 plus or minus 0.005 and the 2 mm O.D. one is 0.975 plus or minus 0.005 up to flow Mach number of 3.5. The probe response is only slightly dependent of Reynolds number. By positioning of the thermocouple junction at the vent holes position its output becomes sensitive to disturbances, such as shock waves in the flow. This characteristic of the probe can be useful in mapping of discontinuities in complicated flow fields.
