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.
Calibration Port
It comes with a barb fitting on the end of the GDS-IR, just remove the cap and connect the Tygon calibration tubing.
