Hydrophone boost in the offing

Morgan Advanced Materials is able to manufacture fully encapsulated hydrophone assemblies in a move that sees it further expand its capabilities in high-specification piezo ceramic (PZT) components for defence and commercial sonar applications.

The company is an established manufacturer of PZT plates, discs, tubes and (omnidirectional) spherical hydrophones. These are used in both active and passive sonar applications to aid navigation as well as detect objects such as divers. They can provide one-, two- or three-dimensional information on the size, position, distance and movements of objects beneath the surface.

The company can supply everything from the base piezo ceramic material, to complete and fully encapsulated hydrophone units, and is able to design and manufacture custom hydrophones.

Accuracy and performance can be optimised on planar tube hydrophones, for example, by using the company's enhanced striping capabilities which ensure the creation of regular, repeatable patterns on the inside surfaces of PZT tubes. These can be pre-stressed before supply for increased performance should that be required.

Dr. Peter Thomas, a senior transducer engineer at Morgan Advanced Materials, said: "Many are keen to reduce the size of their supply chains, so being able to provide complete hydrophones, combining state-of-the-art materials, design, underwater testing facilities and manufacturing, positions us ideally to maintain and develop our business in this sector."
