A device for the measurement of the three orthogonal components of an electromagnetic field.

摘要

The measuring device measures an em field at a given point in space (O) using several sensors (CX1-CZ2) arranged in three pairs aligned along three orthogonal axes (X1-X2, Y1-Y2, Z1-Z2) to measure a magnetic field. The axes pass through the point in space (O). Each detector comprises a magnetisable core, with a coil wound around it. The detector coils are connected together in pairs in series in a feedback circuit, and the terminals of the feedback circuit are then connected to the measuring circuit. ADVANTAGE - Measures field components along three axes, without causing perturbation of field.
