DEVICE FOR RECORDING WATER ENVIRONMENT MICRODISPLACEMENTS Russian patent published in 2010 - IPC G01P13/00 G01N27/06 

FIELD: electricity.

SUBSTANCE: device for recording microdisplacements of water environment includes electrodes located in test medium, direct current source and recorder; at that, electrodes are located in pairs in three mutually perpendicular axes at equal distance from the centre of their intersection. In the centre there is the seventh electrode connected to three direct current sources, each of which is connected with its opposite pole to a pair of resistors connected to electrodes of one and the same axes, which form with conductivity of ion environment in which there are electrodes, electric bridge to the diagonal of which a recorder is connected.

EFFECT: enlarging capabilities of the device, improving accuracy and dynamic range.
