Rosemount Analytical Inc. A Division of Emerson Process Management Description 1-3
World Class 3000
6. Suitable for use in temperatures up to
1300°F (700°C).
7. Heater power supply allows World
Class 3000 probe to be interfaced with
existing analog and 218A digital
electronic packages.
8. Optional explosion-proof HPS enclo-
sure allows use in hazardous gas
areas.
e. Handling the Oxygen Analyzer
It is important that printed circuit
boards and integrated circuits are
handled only when adequate antistatic
precautions have been taken to
prevent possible equipment damage.
The oxygen analyzer is designed for
industrial application. Treat each
component of the system with care to
avoid physical damage. The probe
contains components made from
ceramics, which are susceptible to
shock when mishandled.
NOTE
Retain packaging in which the oxygen
analyzer arrived from the factory in
case any components are to be
shipped to another site. This packag-
ing has been designed to protect the
product.
f. System Considerations
Prior to installation of your Rosemount
World Class 3000 Oxygen Analyzer with
Heater Power Supply Field Module, make
sure you have all of the components neces-
sary to make the system installation. Ensure
all components are properly integrated to
make the system functional.
Once you have verified you have all the
components, select mounting locations and
determine how each component will be
placed in terms of available power supply,
ambient temperatures, environmental con-
siderations, convenience, and serviceability.
A typical installation is illustrated in Figure
1-2 and Figure 1-3.
After selecting the probe mounting location,
provision should be made for a platform
where the probe can be easily serviced.
The heater power supply can be located up
to 150 feet (45 m) cable distance from the
probe.
A source of instrument air is required at the
probe for reference gas use. Since the
probe is equipped with an in place calibra-
tion feature, provision should be made for
connecting test gas tanks to the oxygen
analyzer when the probe is to be calibrated.
NOTE
Ambient air is not recommended for
use as high test gas. An 8% O
2
bal-
ance in nitrogen is recommended for
high test gas.
If test gas bottles will be hooked up perma-
nently, a check valve is required next to the
calibration fittings on the probe junction box.
This is to prevent breathing of calibration
gas line and subsequent flue gas conden-
sation and corrosion. The check valve is in
addition to the stop valve in the test gas kit
or the solenoid valve in the multiprobe test
gas sequencer units.
