DYNAMIC PERFORMANCE OF PRESSURE TRANSDUCERS IN SHOCK AND DETONATION TUBES.

Abstract

A method is presented for evaluating the dynamic performance of high frequency pressure transducers on the basis of records obtained by means of shock tube calibration tests. The transducer's frequency response is determined from a Fourier transform analysis. The computations were programmed for the IBM 7090 computer including provision for the use on the cal-comp plotter to produce results describing the frequency dependence of the amplitude ratio, phase angle shift, and time lead between the output and input signal. Performance characteristics were calculated for several typical transducers, demonstrating the utility of the method in delineating frequency regimes where reliable response of the instrument can be expected. A number of commercial pressure transducers were tested in shock and detonation tubes. Records obtained from the former provide information on the natural frequencies and rise times of the sensors, while results of the latter were used to illustrate the effects of rapidly varying pressures and temperatures on the performance of the instruments.
