SITE REQUIREMENTS
The GPC1 system installation is affected by the other components that make up the system in which
GPC1 is being used. Generally, a pressure measuring reference such as a piston gauge or transfer
standard is included.
When selecting and preparing a site to setup a GPC1 system, the following should be considered:
•
Bench Stability:
GPC1 weighs about 24 kg (53 lb). Consider its weight and that of other
components, including possible items to be tested, when selecting a bench.
•
Location of Other Components:
Plan the space required and a convenient layout for the complete
system in which GPC1 is the pressure control component. GPC1 has a
TEST2
port
on its left rear
side. In order to position GPC1 to the right for right-handed access, this is where the reference is
usually connected in a calibration system. If necessary, as an alternative, either of the two (2) top
TEST ports
can also be used (see Section 2.3.4). Select interconnecting tubing and fittings rated to
handle the maximum pressure that will be generated. GPC1 high pressure fittings are all DH500
(equivalent to AE F250C, HIP HF4, etc.). The female DH500
TEST ports
and
SUPPLY port
fittings
are delivered with glands nuts and dummy plastic plugs installed.
If you do not plan to use either of GPC1’s top
TEST ports
, consider where a device or system under
test (DUT) will be connected. Note, however, that the top rear
TEST1 port
is the “clean”
TEST port
(see Section 2.3.4.3). Unused
TEST ports
must be plugged for operation using the DH 500 plugs
supplied in the GPC1 interconnections kit.
If GPC1 is to be used with a
DHI
RPM or PG7202 reference device, the hardware necessary for setting
up in a standard configuration is included in the GPC1 interconnections kit (see Section 2.3.4.1).
•
High Pressure Supply:
Plan the high pressure supply to GPC1. If the high pressure is being
supplied by a
DHI
gas booster, interconnecting hardware to connect the booster output to GPC1
SUPPLY port
is included with the booster (see the gas booster Operation and Maintenance Manual).
The GPC1
SUPPLY port
is DH500 female (DH500 is equivalent to AE F250C, HIP HF4, etc.).
•
Drive Air Supply:
Plan the PDVV drive air supply. The maximum drive air supply is 850 kPa (120
psi) but may be lower depending on the maximum test pressure to be adjusted (see Section 2.3.2,
Table 2). The drive air
PDVV DRIVE AIR port
is on the right, rear side of GPC1. The connection is
1/4 in. NPT female.
•
System Interconnections:
Plan the interconnections between GPC1 and other components in the
system. Minimizing the volume and maximizing the mass of all interconnecting elements will reduce
pressure generation and stabilization time (see Section 2.3.4).
ALWAYS use external tubing and fittings rated for pressures equal to or greater than the maximum
pressure which GPC1 will be used to control.
DH500 F fittings are delivered with disposable, orange, plastic dummy plugs installed. These are NOT
intended to hold high pressure. They should be removed and replaced with appropriate fittings or
stainless steel plugs before high pressure operation. Each dummy plug carries a DH500 collar.
Remove and retain the collar for use in connecting to the fitting.
