1 - 4 SECTION 1 - INSTALLATION
Installing the Pressure Transducers
1. If the pressure transducers have been shipped installed in the instrumentation cabinet,
then no action is required.
2. If the pressure transducers have been shipped separately (to prevent damage from the
heavy transducers to the other parts in the instrumentation cabinet, during shipping), then
just open the cabinet door, and connect the transducers by matching up the transducer to
its labeled unused tube fitting.
3. If the fittings are not labeled, then use the Flow Diagram/Schematic in Section 7 of this
manual to find which tube is which. If the pressure transducers are not labeled, match the
serial number of the transducers to the note on the manufacturer Certificate of
Calibration.
4. Alternately, you can just make a note of which serial number transducer you install to
measure each pressure, and then perform your own Automatic Calibration for each
transducer, as discussed in
Section 4 – Calibration .
Connecting Utilities
1. Connect an air pressure supply to the AIR SUPPLY INLET connection on the back of the
CHA instrumentation cabinet. See the
Utilities and Environmental Requirements
earlier in this section for minimum and maximum pressures required, and the types of
connectors and tubing required.
2. Connect a vent line (tube) to the GAS VENT connection on the back of the CHA
instrumentation cabinet and run this tube to a vent hood (or outside the building), if
desired. See the
Utilities and Environmental Requirements earlier in this section for
the types of connectors and tubing required. This is an atmospheric-pressure line, and is
not absolutely required, since the gas vented should only be nitrogen (N
2
).
3. Connect a high-pressure nitrogen (N
2
) gas supply (such as from a gas bottle) to the GAS
(N
2
) INLET connection on the back of the CHA instrumentation cabinet. See the Utilities
and Environmental Requirements earlier in this section for minimum and maximum
pressures required, and the types of connectors and tubing required.
4. Connect a pressurized water (H
2
O) supply to the H
2
O INLET connection on the back of
the CHA instrumentation cabinet. See the Utilities and Environmental Requirements
earlier in this section for minimum and maximum pressures required, and the types of
connectors and tubing required.
5. Connect a drain line (tube) to the H
2
O PURGE connection on the back of the CHA
instrumentation cabinet. We suggest you use the 1/8” -OD PFA tubing, which is included
in the #7200-ACCESS accessory kit and run this tube to a small beaker next to the CHA
instrument. See the
Utilities and Environmental Requirements earlier in this section
for the types of connectors and tubing required. If you use the tubing mentioned above,
you can use the connector which is included in the #7200-ACCESS accessory kit that
comes with the CHA.
