Introduction

Acoustic imaging technology, pioneered by Fluke Process Instruments, uses an array of microphones to capture and analyze sound waves. These sound waves are then converted into visual images, allowing for precise localization of sound sources. This technology has proven invaluable in various industries, including mining, for its ability to detect and pinpoint potential issues before they escalate.

Applications Within the Mine: 

Acoustic imagers from Fluke offer numerous benefits in mining operations, including:

• Leak Detection: Accurately pinpoint leaks in pipes, valves, and other equipment, preventing waste and reducing downtime.
• Equipment Monitoring: Detects mechanical issues in rotating machinery, conveyors, and production lines, enabling proactive maintenance and preventing costly breakdowns.
• Conveyor System Optimization: Identify potential problems in conveyor systems, such as misalignment, bearing wear, or material buildup, ensuring smooth and efficient operation.
• Electrical Partial Discharge Detection: Detects and locates partial discharge issues in high-voltage equipment, preventing failures and improving safety.
• Compressed Air System Optimization: Optimize compressed air systems by identifying leaks and inefficiencies, reducing energy consumption and costs.

How Fluke Acoustic Imagers Work

Fluke acoustic imagers use an array of highly sensitive microphones to capture sound waves in a wide range of frequencies. Advanced software algorithms then process these sound signals, creating a visual image that overlays the sound information onto a real-time video image. This allows operators to quickly and easily identify the source of abnormal sounds and take corrective action.
