HIGH-PRECISION PRESSURE SENSOR.

Abstract

Progress made during the quarter 8 May 1963 through 7 August 1963 toward development of a zero to 2500 psi pressure sensor having an over all precision of 1/4 psi is summarized. Present emphasis is on techniques involving sensing pressure through its effect on the velocity of sound in liquids. Laboratory model equipment is described and test results are presented which are interpreted as experimentally verifying that 1/4 psi pressure sensing via the velocity of sound is possible in the laboratory. Some general requirements for pressure sensors to be used as torpedo depth sensors are outlined and problems associated with using the velocity of sound approach are identified. Two approaches to the most fundamental problem (temperature discrimination) are described and experimental results with one of the techniques are given. (Author)
