The GDS-58NXP sample draw system is
an ideal solution for applications where
ambient conditions are unsuitable for
traditional ambient sensors, or where
access to an ambient sensor would
be inconvenient or dangerous. The
GDS-58NXP sample draw features the
new GASMAX CX gas monitor with
DigitalSensor technology and advanced
Ethernet / MODBUS communications.
Together with a fully integrated long-life
brushless sample pump, adjustable flow
meter and low flow warning switch, the
highly reliable GDS-58NXP can monitor
locations up to 500 feet away.
GASMAX CX Gas Monitor
The new GASMAX CX dual channel gas
monitor supports new GDS Corp Digital
Sensors for toxic and combustible gases
as well as volatile organics and inert gases
such as CO 2 . The high contrast full color
graphic display shows system status,
gas values, programmable tag name and
engineering units under full daylight
conditions. Unlike previous generation
detectors with point LEDs, the GASMAX
CX signals alarms by flashing the entire
screen, making alarm indications clearly
visible to operators and technicians. A
menu-driven operator interface eliminates
all analog potentiometers and allows
setup and calibration without hazardous
area declassification. An integrated Run
/ Calibrate valve and user prompted
calibration procedure make routine
maintenance and field ‘bump tests’ quick
and easy.
Reliability in Hostile Environments
Utilizing a long-life brushless DC pump,
the GDS-58NXP Sample Draw is suitable
for installation in hazardous areas rated
Class I, Div 1, Groups B, C & D.
The GDS-58NXP is ideal for sampling
toxic or combustible gases in:
- Sumps and enclosed areas

GDS-IR Features
The GDS-IR Infrared Gas Sensor uses
proven, reliable infrared sensing technology to detect dangerous levels of carbon
dioxide or explosive levels of methane,
propane and other hydrocarbons. The
GDS-IR sensor is CSA certified for use
in Class 1 Division 1 explosive environ-
ments and is CSA performance tested.
Advanced Infrared Technology
The GDS-IR infrared combustible gas
sensor offers low total cost of ownership
and a seventeen-year MTBF rating. Designed for especially harsh environments,
the GDS-IR is virtually maintenance-free
and immune to poisoning or etching by
any known gas. The sensor element features a self-compensating optical bench,
heated optical chamber and fault indication for all failure modes. The optical path
can be easily opened for cleaning.
No periodic span calibrations are required.
On initial setup and after each cleaning,
a simple ‘auto zero’ procedure is used to
establish proper operating conditions.
Flexibility
The GDS-IR can be calibrated to read a
wide range of combustible hydrocarbons,
including methane, propane, hexane,
pentane, ethanol, Jet-A, isobutane,
propylene and isoproply alcohol, as well
as carbon dioxide to 5% by volume.
GDS-IR sensors are factory programmed
and calibrated when shipped and can be
field programmed for alternate response
curves. Both LEL and % by volume
ranges are available.
GASMAX + GDS-IR Combo
When combined with the GASMAX II
monitor, the duo provides local display,
4-20mA output with diagnostics, optional
second electrochemical sensor, isolated
4-20mA outputs or MODBUS slave
interface with programmable relays.
Reliable Detection
The GDS-IR is manufactured in the
USA and includes a five year operational
warranty. Applications include refineries,
onshore and offshore drilling platforms,
fuel loading docks, biogas processing,
breweries, wastewater treatment facilities
and natural gas storage and distribution.
