Popis: In this paper, the dynamic behavior of a strain gauge pressure transducer is analyzed with the one‐dimensional elastic wave theory. An infinite series type formulation for the output strain of the transducer is put forward and proved to be correct by comparing the analytic results with those from experiments. Analysis on a real pressure transducer suggests that the transducer will be unreliable as the rise time of a pressure pulse is too short (e.g., less than 500 μs), and the maximum pressure readings will be either much too high or much too low, depending on the rise time and the base length of the strain gauge, etc. The results presented will be helpful for practical dynamic pressure measurements.
