MEASUREMENTS ON FREE-FLOODED MAGNETOSTRICTIVE RINGS

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. The report is concerned with measurements which show how spacing between free- flooded coaxially mounted rings in a line array affects acoustic beam patterns, bandwidth, and efficiency. Information on individual rings is provided as an aid to a better understanding of some measurements made on the array.
