STL Coil Systems STL Coil Systems can be used for calibration of several types of magnetic field sensors as e.g. hall sensors, AMR, Fluxgates and SQUIDs. Coil Systems are comprising STL Coil Systems are built up in compact way with highest requirements in terms of homoge- neity, orthogonality and stability. Q Controller System with magnetic field or gradient sensor (option)) The coils access area can vary acc. to customer requirements and necessity of homogeneity.

Braunbek, Barker and Maxwell Coils exhibit 4 coils per axis. With Braunbek Coils the * * * * $ $ $ $ product of the number of turns and the currents $ $ $ $ $ $ $ $ $ are identical for each coil. With Barker coils all coil diameters are the same. With Maxwell Coils $ $ $ $ $ $ $ $ $ $ the single coils are lying on the surface of a $ $ $ $ $ $ $ $ $ $ sphere.
