Magnet Assembly
The magnet assembly attaches to the rheometer's rotating spindle,
and then lowers over the rotor assembly. The spindle collar of the
magnet assembly includes an insert adapter. The adapter insert
should remain in the collar for use with AR2000 or AR2000ex
rheometers. If using the pressure cell with an AR-G2 rheometer,
take the adapter insert out of the spindle collar by removing the
two Phillips (or cross head) screws extending for the outer surface
of the spindle collar. See the figure below. Like the rotor assembly,
the magnet assembly contains a 4-pole magnet. When the spindle
and magnet assembly are rotated, the attraction between the two
4-pole magnets produces a corresponding rotation of the rotor.
There is no physical contact between the two assemblies.
CAUTION: Do not place magnetic storage
media near the magnet assembly, as it con-
tains a powerful magnet capable of destroying
magnetically recorded material.
