The UE Systems Si2-LD Acoustic Imaging Camera represents the next-generation milestone in acoustic condition monitoring, specifically engineered for pressurized leak quantification and mechanical anomaly diagnostics across industrial processing facilities. The instrument translates inaudible acoustic waves generated by turbulent gas leaks and rotating friction anomalies into high-contrast acoustic heatmaps superimposed in real time over a crystal-clear digital video feed.

Engineered to surpass previous-generation acoustic cameras, the Si2-LD detects smaller leaks at more than twice the distance while adding dedicated mechanical fault evaluation for bearings and conveyor idlers. This allows maintenance teams and energy auditors to inspect extensive facilities covering tens of thousands of square meters rapidly and safely from floor level.

Key Engineering Features & Operational Advantages:
- 124 Advanced Digital MEMS Microphone Array: Optimized multi-transducer circular spiral arrangement delivers high spatial resolution and an elevated signal-to-noise ratio (SNR). The Si2-LD isolates minute leak anomalies even amidst deafening industrial background noise (such as stamping presses, rotary compressors, and turbines).
- Extended 2 kHz to 130 kHz Dynamic Frequency Range: While conventional acoustic cameras terminate near 35 kHz, the Si2-LD extends bandwidth capabilities up to 130 kHz. This broad ultrasonic range captures high-velocity gas turbulence and separates early-stage bearing defect frequencies from factory ambient noise.
- Dedicated On-Device Mechanical Fault Mode: In addition to pressurized gas leak auditing, the Si2-LD incorporates embedded analytical algorithms that detect early mechanical anomalies in rotating bearings, conveyor idler rollers, and gear sets, grading fault severity on-screen to prevent unplanned downtime.
- 12 Megapixel Visual Camera with 8x Digital Zoom: Delivers crisp visual documentation, allowing operators to zoom in smoothly on high-elevation pipe racks, structural trusses, and dangerous machinery zones from safe stand-off distances up to 200 meters.
- Automated On-Device Sizing & Energy Cost Estimation: Built-in algorithms compute real-time leak flow rates (l/min or CFM) and project annualized electrical energy loss in local currency, directly supporting ISO 50001 energy management compliance.
- 5-Inch Full HD Sunlight-Readable Touchscreen: 1280 x 720 pixel resolution with 1000-nit luminance ensures readability under intense direct outdoor sunlight. Up to 60 fps acoustic frame rates deliver fluid tracking without display lag.
- IP54 Industrial Enclosure: Built to withstand dust infiltration and omnidirectional water splashing in harsh chemical plants, pulp mills, mines, and automotive assembly facilities. Cloud integration and Wi-Fi sync streamline fleet management and automated reporting.

Typical Industrial Applications:
- Pinpointing pressurized air, vacuum, and steam leaks across distribution manifolds, fittings, and automated machines.
- Locating costly or hazardous specialty gas leaks including Argon, Nitrogen, Hydrogen, CO2, Oxygen, and natural gas.
- Mechanical condition monitoring of overland conveyor idlers and electric motor bearings in mining, cement, and pulp facilities.
- Comprehensive energy audits in compressed air utility rooms and industrial piping networks.
