MPAC208 Acoustic Imaging Camera

Professional Acoustic Imaging Camera

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

At its core is a 208-channel MEMS microphone array with sensitivity from 2 kHz to 100 kHz, letting the camera detect very small leaks and subtle ultrasonic patterns. Acoustic data is fused with a 13 MP optical camera and presented on an 8-inch capacitive touchscreen as a clear, real-time overlay that makes sound sources immediately visible.

With a detection range up to 200 meters, the camera works for close-proximity inspection as well as stand-off safety at substations, switchgear, and overhead line work. The Focus function suppresses background noise so operators can isolate a target source even in loud plants, while SoundScan directional guidance helps trace sources outside the visible frame.

Three operating modes cover the core applications. Gas Leak mode automatically estimates leak rate, cost impact, and distance to the source. Partial Discharge mode captures PD activity with Phase Resolved Partial Discharge (PRPD) analysis to support early detection and classification of discharge types. Mechanical mode identifies bearing wear, valve leakage, cavitation, and vibration-related wear through their ultrasonic signatures.

The camera weighs 1.4 kg, carries an IP54 rating, and runs up to 10 hours on interchangeable smart batteries (two 5-hour packs included). An optional thermal imaging module adds side-by-side acoustic and thermal views so heat signatures can be correlated with acoustic anomalies for faster root-cause assessment.
