Figure 3. This diagram illustrates the moduler product design that goes into a
gas detector when designed by Honeywell for the widest range of installations, including
the newly emerging SIL 2 and Foundation Fieldbus requirements. It shows
the various sensing technologies that it can support (catalytic bead, electrochemical,
infrared) so that it can detect the widest range of gases, and it shows the various
communications technologies that it can support so that it can serve in a range
of installation requirements
When you face intense processing
conditions, look to centrifuges
from GEA Westfalia Separator.
That's because they are built to
operate safely even under the
most extreme temperatures and
pressures. Here are just a few
features offered:

director of product marketing with
RAE Systems (San Jose, Calif.). " If
one of the fixed detectors in an area
goes down, they have to do maintenance,
which can be disruptive and
difficult, " he says. So, RAE Systems
has designed the MeshGuard, a semifixed
system that can be applied to
a process from a few days to a few
years. " It is designed to behave like a
fixed system, but has a wireless mesh
radio that gives it a lot of flexibility
that you don't have with a traditional
fixed system, " he says.
MeshGuard is rapidly deployable
in industrial and remote monitoring
applications and combines advanced
gas-detection technology for industrial
safety applications using the
latest in connected data systems. Because
the system contains wireless
sensors that can be set up quickly in
any environment, MeshGuard eliminates
the need for lengthy and expensive
installation projects. By detecting
and recording a range of gases
and quickly relaying the data to an
easy-to-understand central system,
safety personnel have access to upto-date
information from throughout
the network of sensors.
Flexibility is also a key option
with Oldham's OLCT 200 gas detection
transmitter. This fixed detector
is designed for use with multiple
gas detection technologies, including
electrochemical, catalytic-bead, infrared
and photoionization detection
sensors. This allows the unit to detect
many typical gases and provides
users with the ability to standardize
on one transmitter for all of their detection
needs. The unit is also capable
of monitoring two different gases simultaneously,
and provides the ability
to mount sensors away from the
transmitter and display for remote or
difficult to reach locations.
The OLCT 200 is designed for application
flexibility, according to Lange,
as it is compatible with nearly any
fixed gas-detection installation. It
