012731-504 | Det-tronics FlexSight LS2000 Line-of-Sight Infrared Hydrocarbon Gas Detector

DescriptionThe FlexSight™ Line-of-Sight Infrared Hydrocarbon Gas Detector model LS2000 is a gas detection system that provides continuous monitoring of combustible hydrocarbon gas concentrations in the range of 0–5 LFL-meters, over a distance of 5–120 meters. Standard system outputs include an electrically isolated/non-isolated 4-20 mA DC current output, with HART communication 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 fixture hardware. Both modules are powered from an external 24 volt DC supply. 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.The LS2000 is certified explosion-proof for use in Class I, Division 1 and 2; Class II, Division 1; Class I, Zone 1; and Zone 1, Zone 2 hazardous areas and holds 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.By connecting the transmitter and receiver via a three-wire shielded cable, an optional “communication link” can be created between the two devices to enable: single point system diagnostics, dynamic lamp power optimization, synchronized LEDs, transmitter configuration via connection to the receiver, and calibration initiation from either device.Features and Benefits± 0.8 degree misalignment tolerance (~±56cm @ 40m; ~±168cm @ 120m)IR source: High performance, long lasting xenon flashlamp - 10 year warranty on IR sourceLarge detection coverage area (detection range 5–120 meters)Maximum distances and proper operation verified with 95% signal obscurationGlobal compliance to FM6325, ISA-12.13.04, EN 60079-29-4, and IEC 60079-29-4 performance standardsCertified SIL 2 capableThird party performance certified and factory calibrated to Methane, Butane, and PropaneMicroprocessor controlled heated optics for increased resistance to moisture and iceStandard 4–20 mA output (configurable), HART communication, RS-485 ModbusOptional alarm relays (Ex d only)Mounting hardware and alignment brackets includedMounts to pole (4.5” nominal OD) or flat surfaceBuilt-in locking adjusters deliver fine control of alignment anglesTelescope is the only tool needed for optimal alignmentMulti-color LEDs are provided on both modules for detailed visual indication of operating statusNon-intrusive zero calibration options: on-board magnetic switch, Modbus communication, HART communication, or external switchOptional 475 field communicator unit for communication, diagnostic, and set up from point to pointModular design for ease of maintenanceEQP compatible version available.
