Megger MPAC208-IECEx Offers

The MPAC208 is a professional-grade acoustic imaging camera designed for fast, accurate detection of ultrasonic sound sources across industrial environments. It helps maintenance teams identify gas leaks, mechanical deterioration, and partial discharge (PD) in high-voltage electrical systems, without needing to interrupt operations.

At its core is a 208 channel MEMS (micro-electromechanical system) microphone array offering sensitivity across 2 kHz to 100 kHz, enabling the MPAC208 to detect even very small leaks and subtle ultrasonic patterns.

The acoustic data is fused with a 13 MP optical camera and displayed on an 8-inch capacitive touchscreen, presenting clear, real-time visual overlays that make sound sources immediately visible.

The MPAC208-IECEx camera provides all the features seen in the standard MPAC208 but is certified for use in Class 2 explosive atmospheres.

Features

• Precise leak detection: Effortlessly pinpoints pressurised and vacuum gas leaks, minimizing downtime and reducing energy losses
• Advanced electrical inspection: Includes Phase Resolved Partial Discharge (PRPD) analysis for clear identification and discrimination between different types of partial discharge in electrical systems
• Mechanical fault identification: Detects mechanical deterioration in rotating equipment, valves, and bearings through ultrasound monitoring, enhancing predictive maintenance
• Quantifiable leak rate assessment: Built-in analytics quantify leak rates, helping estimate energy loss and prioritise repairs based on cost impact
• Noise suppression with focus function: Focus feature minimizes unwanted background interference, providing clear, actionable acoustic images, even in noisy industrial environments
• Ultrasound to audible sound conversion: Converts inaudible ultrasonic emissions to audible sound for intuitive identification and pinpointing of leak sources
• SoundScan™ directional guidance: Proprietary SoundScan™ technology directs the user to the primary sound source, even when it is outside the camera’s visual field
• Field-upgradable firmware: Stay current with easy firmware updates via USB-C or microSD, ensuring long-term device performance and compatibility
• Acoustic analysis software: Included desktop software enables comprehensive analysis, reporting, and data management post-inspection
• Time-domain graph display: Visualize and analyse ultrasonic signals in real-time with the time-domain graph, helping operators identify signal patterns, duration, and transient events for enhanced diagnostic accuracy
• Acoustic spectrogram visualisation: The built-in acoustic spectrogram displays frequency content over time, allowing users to easily distinguish between different sound sources and track changes in frequency behaviour, especially in complex environments
• Optional thermal imaging modules (sold separately): Add-on thermal imaging modules enables a side-byside view of thermal and acoustic images, allowing for simultaneous detection of temperature anomalies and acoustic events, improving fault correlation and identification
• Optional verification (sold separately): To ensure the MPAC cameras are operating within specified parameters, the Megger MPAC-V acoustic camera verifier can be used (sold separately). This optional tool gives the operator the ability to verify the frequency and SPL measurements of the camera using a dedicated verification procedure. In addition, the camera can automatically check the operation of each MEMS microphone, to ensure optimum performance
