The Si1-LD Acoustic Imaging Camera for Leak Detection, distributed and supported by UE Systems, represents an advanced visual inspection solution that translates inaudible ultrasound waves generated by pressurized gas leaks into vivid, real-time acoustic heatmaps superimposed onto a live digital video feed.

The Si1-LD eliminates the labor-intensive point-by-point scanning required by conventional ultrasound tools. Inspectors simply point the camera at piping racks, manifold banks, or overhead distribution drops from a safe stand-off distance. The display instantly visualizes the exact leak orifice as a high-contrast colored hotspot, allowing facilities to survey large manufacturing plants covering thousands of square meters in a fraction of the time.

Key Engineering Features & Operational Advantages:
- 124 Low-Noise Digital MEMS Microphones: Incorporates an optimized multi-transducer array arranged in a spiral pattern. This configuration provides extreme spatial resolution, isolates leak noise from severe low-frequency plant background noise (such as stamping presses, motors, and blowers), and pinpoints micro-leaks with pinpoint accuracy.
- Real-Time Quantitative Leak Rate & Cost Sizing: Powered by on-board analytical algorithms, the camera measures sound intensity and target distance to calculate real-time flow rate loss (liters/min or CFM) and converts energy waste directly into monetary cost estimates on-screen, streamlining energy audits conforming to ISO 50001 standards.
- High-Brightness Industrial Touchscreen: Features a 5-inch full-color capacitive touchscreen with 1000-nit luminance, providing high visibility under direct outdoor sunlight. A 25 fps acoustic refresh rate delivers smooth, lag-free visual tracking.
- Dedicated 2 kHz to 31 kHz Bandwidth (Extended to 35 kHz): Centered on the primary acoustic frequency signature of turbulent gas flow through micro-orifices while filtering out non-leak industrial background chatter.
- Lightweight One-Handed Ergonomics: Weighs just 1.0 kg (2.2 lbs) with an ergonomically balanced handgrip, allowing single-handed operation and reducing technician fatigue during facility-wide audits.
- Automated Cloud & Software Integration: Captured inspection images and video recordings transfer seamlessly via integrated Wi-Fi or USB to cloud and desktop reporting platforms, generating comprehensive audit reports for repair tracking.

Typical Industrial Applications:
- Pinpointing pressurized air leaks across distribution lines, fittings, FRL units, and pneumatic cylinders in automated manufacturing plants.
- Detecting costly inert or combustible gas leaks including Argon, Nitrogen, Hydrogen, CO2, and natural gas.
- Vacuum system leak testing in pharmaceutical packaging, food processing, and semiconductor manufacturing.
- Compressed air energy waste auditing at central compressor rooms and industrial distribution headers.
