YT2001 Advanced Acoustic Imager & Leak Detector

The YT2001 Advanced Acoustic Imager is a handheld industrial acoustic imaging camera designed to visually locate sound and ultrasonic sources.

Using a 136-channel MEMS digital microphone array, the YT2001 converts acoustic energy into a real-time visual heat map overlaid on the camera image, allowing technicians to quickly identify the exact location of compressed-air and gas leaks, abnormal sound sources and electrical partial discharge.

With an effective detection distance of 0.3–100 m, a frequency range extending to 65 kHz and real-time PRPD partial-discharge analysis, the YT2001 provides a fast, non-contact tool for predictive maintenance, energy-loss reduction and electrical inspection.

Main Inspection Modes

Compressed Air & Gas Leak Detection

Compressed-air leaks can be difficult to locate in a working factory because background machinery noise can mask the sound of a leak.

The YT2001 uses its microphone array and adjustable frequency filtering to isolate high-frequency leak noise and display its location directly on the screen.

Unlike a conventional ultrasonic probe, the operator can scan an entire area from a distance rather than checking every fitting individually.

The system can also provide real-time leak-rate estimation, helping maintenance teams identify and prioritise the most significant leaks.

Typical leak locations

• Compressed-air fittings
• Pneumatic tubing
• Valves
• Flanges
• Couplings
• Regulators
• Hose connections
• Gas systems
• Vacuum systems
• Process equipment

Partial Discharge Detection

The YT2001 also provides a dedicated PRPD – Phase Resolved Partial Discharge analysis mode.

Electrical partial discharge can generate ultrasonic energy before a serious insulation failure becomes visible. The YT2001 allows electrical technicians to scan equipment from a distance and visually identify concentrated ultrasonic activity.

Typical applications include:

• Switchgear
• Distribution panels
• Transformers
• Bushings
• Insulators
• High-voltage connections
• Electrical substations
• Preventive maintenance inspections

Acoustic Imaging

The YT2001 uses 136 MEMS microphones to determine the direction and intensity of incoming sound.

The resulting acoustic information is displayed as a visual overlay on the live image, allowing the operator to see where the acoustic energy is originating.

A 25 FPS refresh rate allows the imager to follow both steady and intermittent sound sources in real time.
