D/70 Spherical Transducer - Moulding

With a combination of broadband frequency response, omni-directional beam pattern and high sensitivity the D/70 has become the most popular hydrophones in the Neptune range of "D" type spherical transducers. The all moulded construction and inherent strength of the PZT ceramic sphere achieves a robust, light weight, corrosion free design making it the ideal choice as a monitor hydrophone for air gun, boomer and other environments where high levels of shock are experienced. Electrical connection to the transducer is by a low noise coaxial cable. The extruded polyurethane outer jacket of the cable enables the design engineer to build the transducer into customised equipment packages and readily obtain a waterproof seal by simple moulding techniques. The D/70 is available with or without acoustic calibration. All calibrations are traceable to National Standards.
