  • DualSense 080Spherical Projector

  • DualSense 080 Spherical Projector

    DualSense 080 is a reliable, horizontallyomni-directional, spherical, reciprocal transducer. Operational over a wide frequency range (10 Hz - 125 kHz) it is ideal for making absolute sound measurement.

    Made from a soft ceramic it is ideal for hydrophone applications. In addition, Due to the DualSense 080’s reciprocal nature, the transducer is equally suitable as a projector.

    The DualSense transducer comes in a protective, durable, polyurethane coating.
