DET-TRONICS FlexSight LS2000 Open Path Infrared Hydrocarbon Gas Detector with Dual-wavelength Infrared Detection, Stainless Steel Enclosure, and 200 Meters Detection Range

DET-TRONICS FlexSight LS2000 is an open-path infrared hydrocarbon gas detector that uses a dual-wavelength infrared beam to detect flammable hydrocarbon gases between the transmitter and receiver. It provides continuous monitoring over long distances (up to 200 m) and is designed for high-risk areas where point detectors may not cover the entire zone effectively. The system is widely used in oil & gas facilities for early detection of gas leaks.

• Dual-wavelength infrared detection – compensates for fog, rain, snow
• Heated optics – prevents condensation and ice buildup
• Long detection range up to 200 meters
• High immunity to false alarms from sunlight and artificial light
• Automatic gain control – maintains signal strength
• Self-diagnostics and fault relay
• Easy alignment with built-in laser pointer
• Stainless steel enclosure for harsh environments

• Detection Range: 5 to 200 m (16 to 656 ft)
• Gas Detected: Methane and most hydrocarbon gases
• Response Time: ≤3 seconds (typical)
• Operating Temperature: -55 °C to +75 °C (-67 °F to +167 °F)
• Power Supply: 24 VDC nominal (18–32 VDC)
• Power Consumption: 11 W transmitter, 7 W receiver
• Output: 4–20 mA analog, HART, Modbus RS-485, relays
• Enclosure: 316 stainless steel
• Protection Rating: IP66 / NEMA 4X
• Approvals: FM, CSA, ATEX, IECEx, SIL 2 capable

• Oil & gas production facilities
• Refineries and petrochemical plants
• LNG terminals
• Offshore platforms
• Pipeline compressor stations
• Large open areas requiring perimeter monitoring

Q: How far can it detect gas?

A: Up to 200 meters line-of-sight.

Q: Does fog or rain affect it?

A: Dual-wavelength and heated optics minimize interference.
