Pressure Manifold
The Pressure Cell includes a
high-pressure manifold
assembly that is connected to
the rheometer frame. The
rigid piping pressure mani-
fold provides strain relief
between the pressure cell
and external high-pressure
connections. It also includes
necessary valves and gauges
for safely pressurizing and
depressurizing the cell. It is
a critical part of the pressure
cell assembly and the pres-
sure cell should not be oper-
ated without the manifold in
place. The pressure mani-
fold, shown in Figure 8.8 to
the right, includes the fol-
lowing:
• Mounting plate and
Sorbothane block. The
Sorbathane block is a
flexible material that
provides flex between
the rigid pressure cell
piping assembly and the
rheometer frame.
• 1/8-inch and 1/4- inch
female NPT fittings for
high-pressure connections.
• Three way valve for pressurizing, maintaining cell pressure, and depressurizing the cell.
• Pressure gauge for monitoring pressure in the cell.
