MEASUREMENTS ON ONE AND TWO LINES OF FREE-FLOODED MAGNETOSTRICTIVE RING TRANSDUCERS

Abstract

Magnetostrictive ring transducers are rugged and relatively insensitive to hydrostatic pressure when used in a free-flooded condition. Therefore, arrays of this type of transducer are ideally suited for deep submergence applications provided acoustic beam directionality is not required. This report is concerned with measurements made on a single line of free- flooded, coaxially mounted magnetostrictive ring transducers and on two lines of meshed rings arranged to simulate segments of a biplanar array. The data presented shows the importance of spacing and arrangement of transducers in relation to the cancellation of generated acoustic pressures along selected array axes and provides information which will be useful in planning tests on a 30 ring biplanar array.
