The new GASMAX CX gas monitor from
GDS Corp delivers quality, performance
and advanced features for the most critical
gas detection applications. Designed
especially for situations where gas
readings need to be transmitted in real
time via a variety of communication
options, the GASMAX CX includes dual
4-20mA outputs and built-in Ethernet port
with MODBUS/TCP and web server. An
optional output board incldues 4X alarm
relays and dual serial MODBUS channels
with data rates up to 115k bits per second.
Widest Variety of Available Sensors
Built-in dual channel electronics allow
the GASMAX CX to support almost any
combination of GDS Corp toxic, bridge
or 4-20mA sensors. Channel 1 features a
dedicated bridge input configuration for
traditional direct catalytic bead sensors,
and both channels support the new 10-
98xx digital output low-noise sensors.
Built-in sensor monitoring circuitry
detects sensor faults or warns of missing
sensors.
Advanced User Interface
The highly visible full color TFT backlit
display makes the GASMAX CX gas
monitor extremely easy to read and
operate, and magnetic switches arranged
around the screen allow users to perform
calibrations or change settings without
opening the enclosure. Bright flashing
yellow or red alarm screens give users
the ability to instantly recognize alarm
conditions and take appropriate action.
Reliable, Dependable, Certified
The GASMAX CX carries a full two-year
warranty and is fully CSA certified for use
in Class I Division 1 hazardous 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.
