Megger MPAC128 – Professional Acoustic Imaging Camera

• Detects multiple gas types and pressurized gas leaks
• Phase Resolved Partial Discharge (PRPD) for discrimination between different types of partial discharge
• Analyze waveform, spectrum, spectrogram, leakage assessment, discharge type discrimination
• IP54 rating; Wide operating temperature range from -20 to 50 degrees Celsius
• 8MP optical camera resolution; 3.04mm fixed focal length; Sound/Camera FOV: Horiz. – 62°; Vert. – 48°

The Megger MPAC128 Professional Acoustic Imaging Camera locates gas leaks and partial discharge threats swiftly and precisely. The MPAC128 is quipped with 128 sensors, this high-resolution acoustic imager enables clear visualization of gas, pressure, and vacuum leaks, as well as electrical partial discharge from safe distances up to 120 meters away. With an IP54 rating, it ensures accurate targeting for repairs, preventing safety hazards, production disruptions, and losses, ultimately saving valuable time, energy, and resources.

The MPAC128 series also packs impressive reliability with the units ingenious self-check function, meticulously verifying internal components’ integrity and guaranteeing flawless operation of the microphone array, providing unwavering performance day in, day out.

Megger MPAC128 and MPAC128-ATEX are hand-held professional acoustic imagers that support both audible and ultrasonic frequencies. The MPAC128-ATEX features a II 3G Ex ic IIC T5 Gc explosion-proof rating.

The cameras use microphone array beamforming technology to acquire, measure and visually display the sound source data, overlaid on a real time high definition video image. By integrating the sound source data with the video image, the changing sound source is dynamically displayed on the screen in the form of a “sound map”.

Both the MPAC128 and MPAC128-ATEX Professional Acoustic Cameras aid the detection of air or gas leaks in both compressed and vacuum systems, even in noisy industrial environments. When used in power systems, they can help to safely and quickly identify partial discharge where dielectric breakdown is occurring.

The cameras are designed and built for use in industrial applications where both moisture and dust may be encountered, with the case built from a strong and durable machined aluminum alloy.

The instruments are simple and convenient to operate. They require adjustment of only two parameters: the measurement frequency range and the dynamic range. They offer both picture and video capture modes, making data recording easy and flexible. Test results can be downloaded from the removable microSD card, or via the USB-C port, to allow for analysis and report generation.

Please ensure all the safety warnings within the user manual are read and understood before operating the cameras.
