IMPORTANT
Be sure to read and understand the
entire instruction manual before installing
or operating the gas detection system.
This product is intended to provide early
warning of the presence of a ammable
or explosive gas mixture. Proper device
installation, operation, and maintenance
is required to ensure safe and effective
operation.
application
The 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.
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 holds third party performance
certification for methane gas detection.
Propane and butane detection are also available
(Det-Tronics verified). It can be used as
a stand-alone detector, or as part of a larger
facility protection system using other Det-Tronics
equipment.
