| 摘 要： | 介绍了用于水下发射膛压测量的压力传感器,针对水下测压时有无充脂所出现的不同现象,以理论推导分析了产生此现象的原因。得出结论:在水下发射装置测压,必须对传感器传压管道进行充脂,以排空管道内的空气,保证传压管的固有频率满足测试要求。

| Abstract: | The pressure sensor used in under water gun,and the abnormal phenomenon in pressure measurement are introduced,the cause of abnormal phenomenon is analyzed in theory.The conclusion is drawn that in pressure measurement under water,the air should be obviated by filling silica gel grease in transfer pressure pipeline,and the intrinsic frequency of the transfer pressure pipeline can be ensured to satisfy with test request. |
