FDG-15 Flux Density Generator  3-axial magnetic excitation of devices under test  Magnetic flux generator for any spatial direction  Accuracy of magnetic field vector with respect to sensor axis at least ± 1°  Earth magnetic field cancellation ≤ 1 µT  Homogeneity of flux ≤ 1 % Range of use  Testing of components in research and development  Possible combination with a climatic chamber Description The flux density generator type FDG-15 is a reliable tool for generating a static flux density of up to 3 mT in any direction inside the coil system. The homogeneous magnetic field has a maximum deviation of only 1 percent in the specified dimension. The flux density generator consists of 3 orthogonal Helmholtz coils. Each Helmholtz coil is connected to a DC Power Supply which generates a constant positive current. If it is necessary to compensate also the smallest magnetic fields like the earth magnetic field, it is possible to generate flux densities of less than 1 μT. Due to the design of the exciter, it can be placed within a climatic chamber and tested regarding both parameters – magnetic excitation and variable climatic conditions.
