D/140 Spherical Transducer

The D/140 is one of a group of spherical transducers exhibiting a combination of broadband frequency response, omni-directional beam pattern and high sensitivity. A versatile transducer with a wide range of receiving and transmitting applications the D/140 is equally at home as a cost effective, general purpose hydrophone or as a precision acoustic sensor. The all moulded construction coupled with the inherent strength of the PZT ceramic sphere achieves a lightweight, corrosion free and extremely robust design making it the ideal choice as a monitor hydrophone. The outer jacket of both the cable and moulded stalk are in a polyurethane material, enabling the transducer to be potted directly into customised equipment pods or underwater connectors. The D/140 is available with or without acoustic calibration. All calibrations are traceable to National Standards.
