Development of a Flat Frequency Response Pressure Transducer System.

Abstract

A theoretical prediction to determine the frequency response of a cascaded remote pressure transducer system has been developed. This prediction was used to find a theoretical configuration which would produce a fairly flat frequency response (1.00 plus or minus 0.05) over a 100 hertz range. Such a configuration would allow cross-correlation of an unsteady, random, low-speed flow field by simple analog methods. The theoretical prediction did not hold true for configurations of three serially connected tubes, but the parameters, namely, transducer volume, tube length, and tube diameter, proved the same trends experimentally that were predicted theoretically. By observing these trends, a solution of 1.00 plus or minus 0.09 over a 95 hertz range was obtained. (Author)
