A method for gaining dynamic index of pressure transducer is introduced

the frequency response of pressure transducer is measured through stimulating pressure transducer by cycle pressure wave

then output voltage is collected through using computer with filter solved by software

so spectral property of pressure transducer can be gained.The test results show that dynamic characteristic in full spectral range may be gained by the measurement method easily

it can provide test data for more improving and designing dynamic performance of pressure transducer.
