Fluke ii915 Acoustic Imager: Detect, Locate, and Assess Anomalies

The Fluke ii915 Acoustic Imager is a powerful tool designed to identify and evaluate issues in various systems. With three distinct modes—LeakQ™, PDQ™, and MecQ™—this innovative device empowers maintenance professionals to take proactive measures and prevent costly problems. Let’s explore its capabilities:

Leak Detection with More Sensitivity
LeakQ™ Mode: Detect Hidden Costs

Leaks in compressed air, gas, steam, and vacuum systems can lead to significant financial losses. The Fluke ii915 simplifies leak detection by allowing technicians to visualize sound. As they scan hoses, fittings, and connections, the built-in acoustic array captures decibel levels per frequency. The resulting SoundMap™ overlays on a visual image, making it easy to pinpoint leaks—even during peak operation hours. Say goodbye to time-consuming inspections and hello to efficient leak detection. Fluke ii915 has the high frequency range and best sensitivity to do acoustic leak detection more efficiently.

Early Mechanical Issue Identification
MecQ™ Mode: Efficient Inspection for Conveyor Systems

Conveyor systems are notorious for their complexity and potential to disrupt production. The Fluke ii915 acoustic camera revolutionizes inspection by enabling contactless scanning of large areas. Advanced noise filtering ensures clear images, even in high-noise environments. Detecting potential mechanical issues early allows targeted maintenance, preventing unplanned downtime. For seamless operation and proactive maintenance of large conveyance systems, the Fluke ii915 Acoustic Imager with MecQ™ is the ultimate choice.

Visualizing the Invisible Threat
PDQ™ Mode: Locating Partial Discharge

Partial discharge poses serious risks, from arc flash fires to blackouts. The Fluke ii915 translates partial discharge sounds into visuals, precisely pinpointing their location. With an extended frequency range of 2-100 kHz, this tool can detect partial discharge even earlier and aids maintenance planning to prevent catastrophic events. High-voltage electricians, electrical test engineers, and grid maintenance teams can now see what was once invisible.

Key features
• Enhanced Performance: Improved detection performance for gas leaks, electrical discharges, and mechanical issues.
• LeakQ™ Mode: Estimated leak size and cost.
• PDQ Mode™: Assesses discharge severity.
• MecQ™ Mode: Proactively address potential problems in rotating mechanical components.
• Reporting Features: Integrated visual and textual tagging and annotation functionalities for streamlined reporting.
• Wireless Upload: Easily transfer data to Fluke Connect.
