NSW 2D Current Meter
The NSW current meter is a 2D-component current sensor, which is based on induction principle (Faraday's law).
A magnetic field is generated vertical to the gauge head (Ellipsoid). By a current with the velocity V a voltage U is induced between vertical fixed electrodes on the surface of the gauge head. Using the two electrodes, which are arranged vertically to each other, allows measurement of the current components (x- and y-directions) in the level of the measuring head.
The NSW current meter is robust and stable and very easy to assemble. A conversion system is used for the data transmission to a PC-XT or to an AT-compatible computer.
