摘要： Submersible transducer includes a transducer housing configured to be submerged within an aqueous liquid and a pressure sensor operable to obtain data for determining a pressure of the aqueous liquid. The pressure sensor may be disposed within the transducer housing. The submersible transducer also includes a submersible cable having an electrical conductor and a venting tube operably coupled to the pressure sensor. The pressure sensor uses an atmospheric pressure of an external environment that is detected through the venting tube to determine the pressure of the aqueous liquid. The submersible cable also includes a cable jacket and an inner layer that is surrounded by the cable jacket. The inner layer surrounds the electrical conductor and the venting tube. The inner layer includes a non-hygroscopic polymer that is more resistant to absorbing the aqueous liquid than the cable jacket.
