REMOTE PRESSURE SENSING
The T9000 series pressure controllers can sense
pressure from a remote location in the process
system by employing the remote pressure sensing
port. Remote pressure sensing can be usefull for
improving system response and eliminating the
pressure drop associated with air flowing through
the outlet tubing between the pressure controller
and the process.
Remote pressure sensing is accomplished by
removing the remote sensing port plug and inserting
the 21665-* remote pressure sensing adaptor in the
port. This special adaptor blocks the pressure
sensing passage coming from the outlet chamber of
the pressure controller and makes the on board
feedback pressure sensor connection available at
the adaptor.
CAUTION:
Because of propagation delays in long
feedback lines, the there is a limit in the length
of the feedback line that can be employed,
otherwise the system pressure will oscillate. In
general terms, the longer the feedback line, the
larger the line must be to affect a stable
system. Adjustment of the T9000's PID
constants may also be required. Be sure there
are no restrictions (kinks in the line or
undersize fittings) in the feedback line. Some
experimentation may be required to determine
the line size for the length of run of the
feedback line.
CAUTION:
To prevent damage to the Remote Pressure
Sense Port Adaptor, support the Remote
Pressure Sense Adapter with a wrench when
installing the air line fitting. For more
information,see Figure 3. below.

PNEUMATIC CONNECTIONS
Clean all pipelines to remove dirt and scale before
installation.
Apply a minimum amount of pipe compound to the male
threads of the air line only.
sealant.
Start with the third thread back and work away
Do Not use teflon tape as a
from the end of the pipeline to avoid the possibility of
getting pipe compound into the air lines.
The inlet and outlet ports are labeled on the bottom of the
Pressure Controller. Tighten connections securely. Avoid
undersized fittings that will limit the flow through the
transducer. For more information, see Figure 1. "T9000
Outline Dimensions" on page 1.
CAUTION:
Oil free air is required. Use a filter to remove dirt and liquid
in the air line ahead of the pressure controller. If an air line
lubricator is used, it MUST be located downstream to avoid
interference with pressure controller performance.
Supply pressure must be no less than 5 psig, [0.35 BAR],
(35 kPa), above maximum output.
Pressure Controller Electrical Connections
ELECTRIC CONNECTION
For the T9000 Pressure Controller, make connections as
shown below in Figure 2. "Electrical Connections". For
compatible cord sets and connections refer to Table 1.
below.
For signal lines of six feet or less, 22 gage wire may be used.
For longer signal lines, use 18 gage wire. Shielded cable
must be used for the signal lines for noise immunity.
