Design and Use of Piezoelectric Gauges for Measurement of Large Transient Pressures

Abstract

This report discusses the design and use of piezoelectric gauges for the measurement of rapidly varying hydrostatic pressures of large amplitude in gaseous and liquid media. Reasons are given for the selection of tourmaline in preference to other types of crystal. Fundamental principles of design are stated, and gauge construction is described in the light of these principles. A simplified theoretical analysis of transient response characteristics is presented.
