Pressure Cell Components
The Pressure Cell consists of four main
component assemblies. These compo-
nents include the pressure cell cup, the
concentric cylinder rotor, the magnet
assembly, and the pressure manifold.
Figure 8.1 shows a schematic cross sec-
tion of the pressure cell cup, rotor, and
magnet assemblies, and Figure 8.2
shows a fully configured Pressure Cell
installed on an AR Rheometer. The
following section will discuss these
four components individually.
The Pressure Cell is shown assembled on the AR rheom-
eter, with the instrument head in the DOWN position, in
Figure 8.2 to the left.
