摘要

A moving-coil measuring system with a large pointer deflection, utilizing a pole ring having a projection, a pole plate with a projection, a permanent magnet arranged between the projections, and a moving coil embracing the pole ring. The shaft of the coil rotates in two bushings which are concentric with respect to the pole ring. One of the bushings is mounted in the pole plate and the other bushing is mounted in a support fastened to the pole plate.
