SONAR TRANSDUCERS

Q. Why does MSI's piezocomposite perform better than monolithic piezoelectric ceramic?

A. MSI's piezocomposite is configured with active ceramic pillars arranged to operate in their length mode, which provides the highest coupling coefficient with higher efficiency and greater bandwidth than conventional configurations. Also, MSI's patented process for injection-molding its piezocomposite material provides a uniformity in the material structure that is superior to monolithic ceramic made using standard fabrication practices. Unlike many transducer manufacturers, MSI also possesses significant expertise in materials science. This expertise allows MSI to design and optimize the matrix and bonding materials in the piezocomposite to achieve maximum transducer performance.

Q. How have MSI's transducers been proven in actual applications?

A. MSI has successfully designed and delivered piezocomposite transducers to a variety of customers for both defense and commercial undersea as well as industrial applications. In the undersea area, MSI's transducers are currently being used for multibeam ocean survey, AUV command & control, acoustic communications, mine warfare and aquatic tracking & assessment applications. MSI's transducers have passed naval shock testing requirements on both sides of the Atlantic.

Q. Does MSI have a catalog of its standard products?

A. MSI does not currently offer a catalog of standard products. However, since 1993, MSI has designed and developed dozens of different acoustic transducers for a wide variety of applications using its piezocomposite technology. This represents a base of experience upon which MSI can build when investigating new transducer designs with its clients. MSI has found that one of its biggest advantages is its ability to provide customers with optimized solutions to their requirements, whereas most catalogs only offer "best fit" solutions to specific requirements.

Q. If I have an application that requires a custom design, how can I work with MSI?

A. There are several ways to work with MSI on a custom design. The easiest way to begin is to use MSI's Sonar Transducer Specification Form, which requests first level information about the application objective for the transducer, the frequency(ies) of interest, acoustic beam pattern and power requirements, mechanical (size & weight) limitations, environmental (pressure & temperature) requirements, and number of units required. MSI will investigate your requirement and explore solutions based upon its extensive base of experience, and then work with you to develop a solution to best meet your needs.
