COOPERATIVE MARINE PILING INVESTIGATION: PHASE 2 - PILE DRIVING AT PEARL HARBOR, HAWAII,
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 pres sure through its effect on the velocity of sound in liquids. Laboratory model equipment is de scribed 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 re quirements for pressure sensors to be used as torpedo depth sensors are outlined and problems associated with using the velocity of sound ap proach are identified. Two approaches to the most fundamental problem (temperature discrimi nation) are described and experimental results with one of the techniques are given. (Author)
