Continuous Leak Detection. Clearer Insight.

The Flir Si2a-LD keeps a constant listen on your pressurized gas systems—continuously detecting, locating, and quantifying compressed-air and gas leaks, including small and intermittent leaks that periodic checks can miss, from up to 200 m (656 ft) away, so maintenance teams can act earlier, reduce energy waste, lower operating costs, and limit exposure to noisy or high-risk areas. AI-enhanced detection and analysis turns leak data into clear, actionable insight with minimal operator intervention, including estimated leak size and annual cost, while its IP66-rated, VESA-mountable design and enterprise-ready connectivity make permanent installation straightforward in harsh industrial environments and easy to integrate with wider condition-monitoring, SCADA, and alarm systems—helping facilities strengthen safety, improve reliability, and prevent unplanned downtime.

Continuous 24/7 monitoring detects even small and intermittent compressed-air and pressurized gas leaks that periodic inspections can miss, helping reduce energy waste, operating costs, and unplanned downtime.
AI-enhanced detection automatically locates and quantifies leaks from up to 200 m (656 ft) away, providing estimated leak size and annual cost so maintenance teams can prioritize the issues that matter most.
With IP66 protection, VESA mounting, and enterprise-ready connectivity, the Si2a-LD is designed for permanent monitoring in harsh industrial environments and straightforward integration with SCADA, alarms, and wider condition-monitoring systems.
