Abstract:

A flexible magnetostrictive hydrophone assembly carried by a multiconductor cable and including at least one sleeve-like flexible hydrophone unit secured in place along the cable. The sleeve-like hydrophone unit has a flexible tubular support core dimensioned for a sliding fit on the cable. The tubular core is a sandwich constructed for pressure release. The core carries a helically coiled magnetostrictive flexible ribbon and a continuous length flexible conductor arranged toroidally around the ribbon helix. The ends of the toroidal conductor are connected to two conductors of the cable and the combination is hermetically sealed. Author
