system. This product is intended to
provide early warning of the presence
of a flammable or explosive gas mixture.
Proper device installation, operation, and
maintenance is required to ensure safe
and effective operation.
APPLICATION
T he Flex Sight™ Line - of- Sight Infrared
Hydrocarbon Gas Detector Model LS2000 is a
line-of-sight infrared gas detection system that
provides continuous monitoring of combustible
hydrocarbon gas concentrations in the range of
0 to 5 LFL-meters, over a distance of 5 to 120
meters. Standard system outputs include an
electrically isolated/non-isolated 4–20 mA dc
current output with the ability to go below 4 mA
to indicate fault conditions, and also HART and
RS-485 Modbus communication. Alarm and
fault relays are available as an option.
Standard system outputs for the LON version are
as follows:
– HART communication
– EQP System S3 Software
– RS-485 Modbus RTU communication
The system consists of two stainless steel
modules — a transmitter and a receiver,
along with mounting and alignment bracket.
The receiver provides the measurement signal
outputs, and is furnished with onboard “status
indication” LEDs and an internal magnetic
calibration switch. The transmitter houses a high
quality xenon flash lamp and “status indication”
LEDs. Both modules are powered from an
external 24 volt DC supply and are equipped
with microprocessor controlled heated optics to
increase resistance to moisture and ice. Both
modules must be installed at approximately the
same elevation and must be aligned to point
directly at one another. No direct electrical
interconnection between the two modules is
required.
The LS2000 is certified explosion-proof for use
in Class I, Division 1 and Division 2 hazardous
areas, and has third party performance
certification for methane, butane, and propane
gas detection. It can be used as a stand-alone
detector, or as part of a larger facility protection
system using other Det-Tronics equipment.
