CONFORMABLE CONVERTER OF SEA WATER HYDROPHYSICAL PARAMETERS Russian patent published in 2008 - IPC G01N27/06 G01K7/02 G01L9/02 

FIELD: physics.

SUBSTANCE: converter of sea water hydrophysical parameters contains, at least, one gage unit including electric conductivity transducer (ECT) of sea water, including sensor of sea water conductivity transducer, sea water temperature converter, including sensor of sea water temperature converter, pressure transducer. Sensor of sea water temperature converter contains thin isolated copper wire between two hollow thin-walled cylinders. The first hollow thin-walled cylinder is formed by flange in the casing of sensor of sea water temperature converter. The second hollow thin-walled cylinder is tightly attached to the first hollow thin-walled cylinder and the casing of sensor of sea water temperature converter provided with angle holes for sea water flow inside of the first hollow thin-walled cylinder which contains housing. Housing external surface is streamline circular-shaped from incident flow. Sensor of contactless sea water conductivity transducer contains supply and instrument transformers provided in dielectric case and having coils wound on toroidal cores. Sensor of sea water temperature converter and dielectric case of sensor of contactless sea water conductivity transducer are provided with hole for sea water flow and mounted in housing holes. Holes axes are perpendicular to generating line of circular-shaped housing surface and designed in housing symmetry plane having holes for sea water drainage. The external circular-shaped surface of dielectric case of sensor of sea water conductivity transducer incident flow is interconnected to external surface of a casing. Each gage unit has hermetically sealed module containing electronics package assembly. Hermetically sealed module has sealed cable inlet.

EFFECT: improved accuracy of sea water hydrophysical parameters measurements in mobile conditions through elimination of sea water flow disturbance close by converter.
