Reduction of Scatter in Underwater Shock Waves Measurements Made With Piezoelectric Gages,
Abstract
For many years measurements of the shock wave from underwater explosions have been made using tourmaline piezoelectric gages. The results have shown considerable scatter, the source of which has been extremely difficult to determine. As the result of recent work, it is now evident that much of the scatter has been caused by spurious electrical charges generated in or by the gage waterproofing material, and it can be eliminated or substantially reduced by waterproofing the gage with an oil-filled boot.
