Title: Measurement of dynamic pressure in inert and reactive solids by PVF/sub 2/ (polyvinylidene fluoride) and manganin gauges

Abstract

Dynamic pressure measurements in solids subjected to excessive loading conditions have recently been enriched by the deployment of a small, new self-powered, polarization type gauge. The transducer, known as PVF/sub 2/ (polyvinylidene fluoride), is a thin polarized sheet of polymer plastic which contains its own source of energy and does not require any external power supply. For high pressure work the manganin gauge is considered as the transducer of choice. However, even this gauge is undergoing constant modifications and improvements for better resolution and accuracy. Of particular interest is the high resolution which can be attained in the measurement of rapid pressure variation with time in high explosive materials during the pressure build-up as well as during the pressure release phase behind a fully developed detonation wave. Performance of PVF/sub 2/ and manganin gauges is discussed in detail showing both the pros and cons of each type as pertinent to the in situ pressure measurements. Potential values of PVF/sub 2/ gauges are indicated and compared to those of the standard manganin gauges.
