Abstract
Evaluation of the pressure-detecting system should be given in terms of both static and dynamic accuracy. Stablility, lineality, sensitivity, and error of the system were discussed in relation to static accuracy. Frequency characteristics is most important in dynamic accuracy. Because of technical difficulty in determining frequency characteristics by steady-state movements in the high frequency area, a substitute method was developed theoretically. Modification of the method applied to the calculation of frequency response and phase lag of the system in damped oscillation was adequate to calculate frequency characteristics. The method applicable both in critically damped and slightly over-damped system was also mentioned.
