  • Hydrophones

    CTS Valpey Corp.

    Piezo is a critical element in producing a hydrophone for military and commercial underwater listening applications. Hydrophones utilize piezoelectric elements to detect sound pressure waves produced by underwater vessels, animals, and the environment. Hydrophones must have a flat frequency response that is proportional to the magnitude of the sound pressure wave. CTS piezo elements provide this critical function in hydrophones by providing excellent frequency response and high coupling factors necessary in hydrophone applications. CTS materials provide excellent electrical properties for hydrophone applications while allowing the ability to form the piezo element to the desired mechanical structure for the hydrophone.
