Application of PVDF sensor in underwater explosive measurement of week pressure signal

Yan Xiao-mi

Abstract

In order to study measurement methods of week pressure signal,small-dose underwater explosion experiments are conducted in pool to validate the feasibility of PVDF sensor with enlargement circuit in it. Test result shows that consistent waveform curves of shockwave and bubble pulsating pressure are obtained in 5 g TNT underwater explosion in pool. PVDF sensors have the advantages of high frequency response,high sensitivity,simple fabrication and low cost,and can be used to test week pressure signal in underwater explosion.
