Description
The
FGD 3 Oxygen, Toxic
and Hydrogen range
of Gas Detector
Heads use electrochemical
sensor technology to
detect a wide range
of gases.
The detectors
use the industry standard
4-20mA current loop
both to power the detector
and to convey the gas
levels detected to
a control unit. This
means that under zero
gas conditions 4mA
is drawn from the supply,
and under full scale
gas conditions 20mA
is drawn from the supply.
The current varies
linearly for gas levels
between zero and full
scale. The detector
heads use a two-wire
connection.
Weather Guard
An
optional weather guard
is available for installations
exposed to the atmosphere
or contaminants and
is also suitable for
use in other areas
where hosing down takes
place. The weather
guard reduces the possibility
of water or other contaminants
entering into the gas
sensor thereby improving
the overall reliabilty
of the gas detector
in hash environments.The
weather guard is attached
with tamperproof screws
to ensure that it is
not inadvertently removed.
Mounting Kits
A Swivel Mounting Bracket and Ceiling Mounting Kit is available for use with this range of gas detectors. In addition, a duct mounting kit is also available. Please contact Status Scientific Controls to discuss your particular application.
