The UE Systems Si2x-LD Intrinsically Safe Acoustic Imaging Camera is an explosion-protected industrial diagnostic instrument purpose-engineered for hazardous locations and potentially explosive industrial atmospheres. Certified to ATEX, IECEx, and North American HazLoc standards, the Si2x-LD allows maintenance teams and energy auditors to visually pinpoint pressurized gas leaks and evaluate rotating mechanical anomalies in hazardous Zone 2 environments without requiring hot work permits or halting live process lines.

Detecting fugitive emissions, combustible gas leaks, and overheated mechanical components in refineries and offshore platforms traditionally involves time-consuming administrative approvals and labor-intensive manual sniffing methods. The Si2x-LD revolutionizes facility safety by converting inaudible ultrasound and acoustic emissions generated by escaping gas turbulence and bearing friction into real-time color sound heatmaps superimposed directly over a high-resolution 12 Megapixel visual video feed from stand-off distances up to 200 meters.

Key Engineering Features & Operational Advantages:
- Certified for Explosive Atmospheres (ATEX / IECEx / HazLoc Zone 2): Fully engineered to comply with strict intrinsic safety and non-incendive design standards (ATEX: II 3G Ex ic IIC T4 Gc / Class I, Div 2). Internal circuitry, housing materials, and battery packs are designed to eliminate ignition risks in environments where flammable gases, hydrocarbon vapors, or combustible dusts may temporarily be present.
- 124 High-Sensitivity Digital MEMS Microphone Array: Arranged in an optimized circular spiral geometry to maximize directional acoustic beamforming and provide an exceptional signal-to-noise ratio (SNR). The array isolates subtle micro-leaks even amidst the severe ambient noise of running compressors, turbines, pumps, and flare lines.
- Ultra-Wide 2 kHz to 130 kHz Frequency Range: Provides comprehensive acoustic coverage spanning from audible sound into high ultrasonic frequencies, enabling precise frequency tuning to capture turbulent gas velocity signatures while screening out low-frequency factory chatter.
- Dual Operational Inspection Modes:
  1. Pressurized Gas Leak Mode: Pinpoints compressed air, vacuum, and combustible gas leaks (Methane, Hydrogen, Natural Gas, Propane, Ethylene, CO2); embedded algorithms compute real-time leak flow rates (l/min or CFM) and project financial cost losses to support ISO 50001 energy standards.
  2. Mechanical Fault Mode: Analyzes high-frequency friction signatures in rotating roller bearings and conveyor idlers, flagging lubrication breakdown or raceway micro-spalling before components overheat and present ignition hazards.
- 12 Megapixel Visual Camera with 8x Digital Zoom: Delivers clear visual documentation, enabling technicians to inspect high-bay pipe bridges, distillation towers, and safety relief valves safely from ground level.
- 5-Inch Full HD Sunlight-Readable Touchscreen: 1280 x 720 pixel resolution with 1000-nit luminance ensures visibility under intense offshore sunlight. Up to 60 fps acoustic frame rates deliver smooth, lag-free real-time tracking.
- Rugged IP54 Housing: Built to withstand salt spray, industrial dust, and rain splashes. Features 128 GB internal storage and dual-band Wi-Fi for seamless cloud synchronization and automated reporting.

Typical Industrial Applications:
- Offshore drilling platforms, FPSOs, and LNG/LPG carriers for detecting combustible hydrocarbon gas leaks (Methane, Hydrogen, Propane, Butane).
- Petroleum refineries, petrochemical crackers, chemical processing facilities, and bulk fuel storage terminals.
- Early mechanical fault detection on conveyor idler rollers and motor bearings in coal-fired power plants, grain handling silos, and mining operations.
- Non-contact compressed air and instrument gas energy audits in classified hazardous plant zones.
