Abstract : The patent relates to a submersible having an externally mounted hydraulic system which is provided with a differential pressure transducer connected between the supply and return lines which articulate a remotely disposed claw. The transducer is responsive to produce a signal representative of the pressure differential between the internal pressure in the lines. This signal is fed through the pressure hull of the submersible to an internally carried meter to enable the determination of the claw's gripping force. Although the meter actually 'reads' differential pressure, it is calibrated in units of grip force, in this case, pounds (OF FORCE).
