Requirements for External Pressure Source
Fittings are provided for external pressurization up to 138 bar (2000 psi). A high-pressure source must be
supplied with 1/8-inch or 1/4-inch NPT male fittings for connection to the manifold supplied by TA
Instruments. In addition, a means of isolating the source from the manifold, and of relieving the pressure in
the line from the source to the manifold should be provided. Figure 8.9 below shows a typical set up for
external pressurization.
WARNING: Only use TA Instruments' high-pressure manifold when operating the
pressure cell. Ensure that the manifold can be isolated from the high-pressure source
provided by the user, and that there is a pressure vent valve in the line between the
source and the manifold.
