Based on high bandwidth for sensors in shock wave testing, seven sensors for shock wave overpressure testing were applied in dynamic calibration test with shock tube. Four companies including Sinocera Piezrotronics, Inc., Mianyang Qishiyuan SCI. &TECH CO. Ltd, PCB and ENDEVCO provided those sensors. The effects of amplifier characters and installing errors on experimental results were analyzed. The rise time and overshoot of each transducer were measured. The working bandwidth of five different sensors was obtained with parametric modeling. The experimental results show that the sensor 8530B provided by ENDEVCO Inc. has smaller overshoot, 8530B and the sensor 113A provided by PCB Inc. have longer bandwidth.
Key words： shock wave; transducer; dynamic characteristic; shock tube
