The 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.
