Floating magnets

The floating magnet (➥ ➥ ➥ ➥ ➥ Figs. 3-2 to
3-4) is attached to the moving
member of the machine using non-
magnetizable screws (brass, alumi-
num). To ensure the accuracy of the
transducer system, the moving
member must carry the magnet on a
track parallel to the transducer.
The following table provides figures
in [mm] for the spacing which must
be maintained between magnet and
transducer and for the permissible
center offset:
