5.5 Pressure Connections
When making up a connection to an o-ring adapter port use a back-up wrench to
prevent over-stressing the threads in the manifold block.
All of the pressure ports on the rear are female 7/16 - 20 SAE/MS straight threads per MS16142 and
SAE J514 table 14. They require a tube fitting boss seal with an o-ring per MS33656. Mensor provides
female 1/8” NPT adapter fittings with the instrument. The pressure connections can be made to these
adapters with the proper mating hardware. We recommend the use of either Loctite® Hydraulic Seal-
ant or new teflon tape on the threads of any male pipe fitting. Do not use sealant on fittings sealed
with an o-ring. The integrity of each seal is particularly important since even microscopic leaks can
cause errors in pressure measurements. The rear panel connections and a complete pneumatic sche-
matic, including the optional secondary transducer, are provided in the
Maintenance Section
(see
Figures 9.2.1C and 9.2.2B). Requirements for connecting to the ports on the CPC 6000 manifold are
as follows:
5.5.1 Supply Port
Connect a source pressure to the SUPPLY port of each channel. See “Source Pressure” in
Section 4
,
Specifications, for supply pressure requirements for various pressure ranges.
!
Caution
CAUTION: The control channels are completely independent. Separate supply
pressures should be applied to the control channels based on the maximum
pressure range of each channel. Applying source pressure higher than the
recommended pressure can cause permanent damage to the control channel.
Performance can be enhanced with a well-regulated source pressure.
5.5.2 Measure/Control Port
Connect a device to be tested to the MEASURE/CONTROL port. In MEASURE mode the CPC 6000
will precisely measure the pressure at this port.
A pressure value can be selected using the on-screen keypad. That pressure will then be output to the
MEASURE/CONTROL port by switching to the CONTROL mode of operation.
WARNING: HIGH NOISE LEVELS! As pressure decreases compressed gas will
escape out the exhaust port. For ranges above 600 psi high noise levels may result
during such pressure releases. To overcome objectionable exhaust noise either
install a muffler or route the port to a remote location.
CAUTION: Improper use of this equipment may impair protection provided by this
instrument.
