FLIR Si2a-LD Leak Detection Fixed Acoustic Imaging Camera (with WiFi)
The FLIR Si2a-LD Leak Detection Fixed Acoustic Imaging Camera (with WiFi) is designed for continuous, automated monitoring of compressed air and gas leaks in industrial environments. With 24/7 acoustic monitoring, it can identify leaks as they occur, helping maintenance teams find hidden sources of energy loss without relying entirely on scheduled manual inspections.
At the heart of the Si2a-LD are 124 low-noise MEMS microphones that provide acoustic measurements across a 2–130 kHz bandwidth. The camera can monitor from distances of 0.3 m up to 200 m, with directional resolution from 1° down to 0.125°. Real-time sound visualisation and automatic leak recognition make it easier to locate leaks and assess their potential impact.
High-Sensitivity Leak Detection
Leak detection is supported by automatic estimation of leak size and annual cost, allowing teams to understand not only where a leak is occurring but also the potential financial impact. The Si2a-LD has a leak rate detection threshold of 0.0032 l/min at 2.5 m and 0.0044 l/min at 6 m. It can detect gases when they are under sufficient pressure, including compressed air, ammonia, argon, carbon dioxide, helium, hydrogen, methane, natural gas and nitrogen.
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.
Intelligent Monitoring, Wireless Connectivity and Integration
AI-enhanced detection and analysis helps process acoustic information with minimal operator intervention. Continuous monitoring can identify leaks across compressed air distribution pipework, valves, fittings and connections, as well as pressurised gas systems. This makes it possible to identify energy losses, fugitive emissions and potential seal degradation earlier, helping organisations take action before these issues become more costly or create additional operational risks.
Wireless connectivity provides additional flexibility when integrating the Si2a-LD into a monitoring environment. The camera supports Wi-Fi on both 2.4 GHz and 5 GHz networks and is compatible with IEEE 802.11 b/g/n/ac standards. A Wi-Fi antenna is included, providing the hardware required for wireless network connectivity.
Built for Permanent Installation
For permanent installation, the Si2a-LD combines an IP66-rated enclosure with VESA mounting options. It is designed for use outside hazardous zones and can operate in demanding industrial environments where continuous condition monitoring is required. Enterprise-ready integration and data management capabilities also allow acoustic monitoring information to form part of wider maintenance and asset management 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.
