Current needs for small-diaphragm transducers include re-entry measurements on ablation heat shields of Apollo and Gemini spacecraft, transfer standard for condensable-vapor calibrations of gas-sensitive gages, measurement of model and tunnel pressures in hypersonic helium blowdown tunnels, etc; promising approaches to meet such needs are reviewed with emphasis on bonded semiconductor (piezo-resistive) strain gage, and capsule, or diaphragm-type, transducers; design approaches are outlined which apply to either flush-diaphragm or cavity instruments at full-scale pressures of 0-0. 5 through 0-50 psia; tabulation of important characteristics.
