A Design for a Hydrostatic Pressure Chamber for Calibrating Piezoelectric Pressure Transducers

Abstract

The measurement of the intensity and duration of underwater shock waves uses piezoelectric transducers permanently sealed to one end of a coaxial cable. A hydrostatic pressure chamber with a fast pressure release for the calibration of these transducers is described. The chamber has been designed to operate at pressures up to 10.4 MN/sq m. Pressure is obtained from a built in manual hydraulic screw pump and the pressure is released by a specially designed quick acting valve.
