Development of a Fast-Response Pressure Transducer,

Abstract:

A small 0.2 inch diameter, fast-response pressure transducer has been developed for measuring shock-interaction induced transient pressures. Transducer design incorporates the Pressure Bar principle to minimize reflections at the boundaries of the sensing element and a unique orifice-cavity method to isolate the sensing element from the external disturbances. Calibration and wind-tunnel shock-interaction data show that this type of transducer is suitable for measuring pressures of 120- to 100-psi magnitude and of 1- to 17-microsecond duration. Transducer performance, design and construction are described. Author
