FLIR Si2-LD Acoustic Imaging Camera

• Leak and mechanical fault detection

The FLIR Si2-LD is an advanced ultrasound camera designed for detecting pressurised leaks and diagnosing mechanical faults. Part of FLIR’s next-gen Si2 series, it helps maintenance teams reduce costly air and gas leaks while identifying early signs of mechanical issues like bearing wear. By visualising sound, the Si2-LD makes it easy to spot energy-wasting leaks and ultrasonic noise from failing machinery. Lightweight and easy to use, it improves efficiency, safety, and maintenance planning.

Reduce Energy Loss from Leaks

Compressed air and gas leaks can be major sources of energy waste. The Si2-LD detects leaks in pipes, valves, and fittings, displaying them as visual hotspots on a live view. Technicians can quickly scan for escaping air or vacuum, enabling fast repairs that lower utility costs and improve system performance.

Detect Mechanical Issues Early

The Si2-LD also recognises ultrasonic sound patterns from mechanical faults like bearing wear, gear issues, or pump cavitation— often before they‘re picked up by vibration or thermal tools. Early detection allows for proactive maintenance and reduces unplanned downtime.

Smart and Simple to Use

Ergonomically designed for one-handed use, the Si2-LD works even in noisy environments thanks to its 124-microphone array and smart noise filtering. On-camera tools estimate leak size or fault severity, while saved images and cloud connectivity support documentation and reporting—streamlining maintenance from detection to resolution.

The FLIR Si2-LD helps reduce facility costs by detecting leaks and mechanical issues early. It supports proactive maintenance, improves decision-making, and integrates easily with enterprise systems—raising the bar for acoustic imaging performance.

FLIR Si2 -LD Key Features:

• Detects, locates, and measures compressed air and gas leaks; including bearing fault detection, from up to 200 m (656 ft) away
• Built-in measurement and cost analysis for industrial gases including ammonia, hydrogen, CO2, methane, helium, and argon
• One-handed operation with automatic tuning, 8x zoom, and a 12 MP digital camera
• Mechanical fault mode, automatic selection, and optimization of filters simplifies finding critical mechanical issues, such as bearing faults
• Fleet management functionality for efficient tool usage and maintenance across large-scale operations

FLIR Si2 -LD Applications:

Comprehensive Leak Detection

The FLIR Si2-LD excels in detecting and quantifying leaks across manufacturing, production, and assembly environments—anywhere compressed air is used. Its advanced capabilities support early leak detection to improve safety, ensure compliance, and reduce repair costs.

Fast, Accurate Leak Identification

The Si2-LD provides rapid and precise detection of compressed air and gas leaks, helping technicians quickly locate issues. This improves maintenance efficiency and enhances customer satisfaction by reducing energy loss and system downtime.

Mechanical Fault Detection

Beyond leaks, the Si2-LD includes a mechanical fault mode that identifies problems like faulty bearings. Early detection allows for better maintenance planning and helps avoid unexpected equipment failures.

Advanced Leak Detection Range

Whether it’s a faint hiss or a difficult-to-detect leak, the Si2-LD can locate and measure leaks from distances of up to 200 meters (656 feet). This long-range capability makes it a powerful tool for maintaining safety and efficiency across large facilities.

Bearing Fault Analysis

Detect bearing defects early with the Si2-LD to prevent costly equipment damage. By spotting issues before failure, you can save on repairs, minimise unplanned downtime, and optimise maintenance scheduling.

Fleet Management Integration

Ideal for large-scale industrial operations, the Si2-LD supports efficient fleet management through cloud-based data integration and over-the-air (OTA) software updates. Combine both acoustic and thermal imaging in a single report for comprehensive diagnostics and streamlined reporting.
