Abstract
An acoustic sensor module, contains groups of single sensor elements within a fluid-tight enclosure. The enclosure is bounded by a reinforced hose wall and module end caps at either end of the module. The sensors are mounted in the center of the enclosure using tubular foam spacers; smaller cylindrical foam spacers fill the central space between sensors. Radial stiffness is provided to the spacers by thin annular rings held in place by fine strength cords. Thin flexible wires connect the sensor elements of each group to the preamplifying/multiplexing electronic package, the connecting leads therefrom being brought out to the outer surface through a division between spacers. Data and power cables are spirally wrapped around the outer diameter, with an over-wrap of fine fiber or plastic tape to lock them into position. The connecting leads to the electronic packages are then spliced into their respective data/power cables. An inner jacket of flexible, low density, acoustically damping thermoplastic material is then extruded over the assembly described above, encapsulating the data/power cables and also enclosing strength members.
