The UE Systems Si2x-Pro Intrinsically Safe Acoustic Imaging Camera represents the ultimate flagship diagnostic instrument in industrial acoustic condition monitoring. Purpose-built for hazardous locations and potentially explosive environments, the Si2x-Pro combines the complete "3-in-1" diagnostic power of the flagship Si2-Pro (gas leaks, mechanical faults, and partial discharge) with rigorous international explosion-proof certifications (ATEX, IECEx, and HazLoc Zone 2).

In oil refineries, offshore drilling platforms, chemical synthesis plants, and bulk gas terminals, traditional predictive maintenance inspections are severely constrained by the need for cumbersome Hot Work Permits or expensive plant shutdowns. The Si2x-Pro solves this fundamental industry challenge through its intrinsically safe and non-incendive design, enabling reliability engineers and safety inspectors to walk directly into live, operating Zone 2 hazardous areas to conduct complete mechanical, electrical, and gas leak evaluations without administrative delays or production interruptions.

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 requirements (ATEX: II 3G Ex ic IIC T4 Gc / Class I, Div 2). Every internal electronic subsystem, housing interface, and battery pack is verified to eliminate mechanical sparks and thermal ignition sources in environments where flammable gases or hydrocarbon vapors may temporarily occur.
- Complete 3-in-1 Diagnostic Capability on a Single Handheld Platform:
  1. Pressurized Gas Leak Auditing (Leak Mode): Pinpoints compressed air, vacuum, and combustible gas leaks (Methane, Hydrogen, Natural Gas, Propane, Ethylene, CO2); embedded algorithms automatically compute real-time leak flow rates (l/min or CFM) and project monetary losses in local currency to support ISO 50001 energy standards.
  2. Mechanical Anomaly Diagnostics (Mechanical Mode): Analyzes high-frequency friction signatures in rotating roller bearings and conveyor idlers, flagging early lubrication failure or raceway spalling before components overheat and present catastrophic ignition hazards.
  3. AI-Driven Partial Discharge Classification (PD Mode): Embedded machine learning algorithms categorize electrical discharge patterns (Corona, Surface Tracking, Arcing, or Floating Discharge), assess failure criticality, and display immediate actionable repair recommendations without requiring external PC software.
- 124 High-Sensitivity Digital MEMS Microphones: Arranged in an optimized multi-transducer circular spiral array that provides extreme acoustic spatial resolution and a superior signal-to-noise ratio (SNR). It easily isolates subtle micro-leaks or faint electrical discharges amid deafening industrial factory background noise (stamping presses, rotary compressors, and turbines).
- Wide 2 kHz to 130 kHz Dynamic Frequency Bandwidth: Offers continuous acoustic coverage spanning audible sound into ultrasonic regimes, ensuring complete isolation of fault signatures from ambient background noise.
- 12 Megapixel Visual Camera with 8x Digital Zoom: Delivers high optical resolution, allowing operators to zoom in smoothly on high-elevation pipe racks, distillation towers, and substation busbars from safe ground levels up to 200 meters.
- 5-Inch Full HD Sunlight-Readable Touchscreen: 1280 x 720 pixel resolution with 1000-nit luminance ensures visibility under intense direct outdoor sunlight. Up to 60 fps acoustic frame rates deliver smooth, lag-free scanning.
- IP54 Industrial Ruggedness: Weighs approximately 1.0 kg (2.2 lbs) with balanced one-handed ergonomics. Sealed against industrial dust, salt air, and omnidirectional water splashing, and features dual-band Wi-Fi for seamless cloud synchronization and rapid automated report generation.

Typical Industrial Applications:
- Offshore oil & gas production platforms, drillships, FPSO vessels, and LNG/LPG transport terminals.
- Petroleum refineries, petrochemical crackers, fuel tank farms, and chemical synthesis plants.
- Medium- and high-voltage electrical substation inspections, switchgear cabinets, and transformer bushing diagnostics located within hazardous plant zones.
- Mechanical monitoring of overland conveyor idler rolls and ventilation fan bearings in coal-fired power facilities, cement plants, and grain handling silos.
