PRESSURE-COMPENSATING SYSTEM FOR GAS-FILLED TRANSDUCERS

Abstract

A self-contained pressure-compensating system has been developed for use with the USRD type J11 moving-coil transducer at ocean depths to 600 ft. This system conserves compensating gas for uninterrupted use over a period of 8 hours or more. It responds to changes in depth by holding the pressure differential on the diaphragm of the transducer to less than 0.7 psi with negligible effect on the acoustic response.
