FLIR Si2a-LD Leak Detection Fixed Acoustic Imaging Camera

FLIR Si2a-LD Leak Detection Fixed Acoustic Imaging Camera

The FLIR Si2a-LD Leak Detection Fixed Acoustic Imaging Camera provides continuous 24/7 monitoring for compressed air and gas leaks in industrial environments. It is designed for permanent installation and helps teams identify leaks as they develop rather than relying on periodic inspections that can miss intermittent or difficult-to-find problems. By detecting problems early, organisations can reduce energy waste, lower operating costs, and prevent minor leaks from becoming more significant operational or safety concerns.

With 124 low-noise MEMS microphones and a 2–130 kHz bandwidth, the Si2a-LD provides detailed acoustic monitoring across a wide range of applications. It can detect acoustic events from 0.3 m up to 200 m away, with directional resolution from 1° down to 0.125°. Real-time sound visualisation helps provide a clear indication of where a leak is located, while built-in automatic leak recognition can estimate both leak size and the associated annual cost of lost compressed air or gas.

High-Sensitivity Leak Detection

The Si2a-LD is sensitive enough to detect extremely small leaks, with detection thresholds as low as 0.0032 l/min at 2.5 m and 0.0044 l/min at 6 m. It detects gases when they are under sufficient pressure, including:

• Compressed air
• Ammonia
• Argon
• Carbon dioxide
• Helium
• Hydrogen
• Methane
• Natural gas
• Nitrogen

By quantifying the leak rate and associated cost, the Si2a-LD can help maintenance teams prioritise repairs based on their potential impact.

Visual Verification

Alongside its acoustic monitoring capabilities, the Si2a-LD includes a 12 MP colour digital camera with a 75° diagonal field of view. Streaming video is provided at 15 fps with a resolution of 960 × 540, while snapshots can be captured at 30 fps. This gives operators additional visual context when locating and assessing detected leaks.

AI-Enhanced Monitoring and Analysis

AI-enhanced detection and analysis reduces the need for constant operator input while helping provide consistent results. The system can be deployed across compressed air networks, including distribution pipework, valves, fittings, and connections, to identify losses that are often invisible to conventional monitoring methods. The same approach can be applied to gas systems and related infrastructure, helping identify pressurised leaks, fugitive emissions and seal degradation at an earlier stage.

Built for Permanent Installation

Designed for industrial condition monitoring outside hazardous zones, the Si2a-LD features IP66 ingress protection for reliable operation in demanding environments. VESA mounting options provide flexibility when installing the camera as part of a fixed monitoring system, while enterprise-ready integration and data management capabilities allow monitoring information to be incorporated into wider maintenance workflows.

Main Applications

Typical applications for the Si2a-LD include:

• Early detection of compressed air leaks across distribution pipework, valves, fittings, and connections to reduce energy waste, lower operating costs, and eliminate the hidden losses that conventional monitoring cannot identify.
• Continuous monitoring of gas systems and associated infrastructure to identify fugitive emissions, pressurised leaks, and seal degradation before they become a safety risk.
