Megger MPAC208 Pro Kit Offers

MPAC208 Acoustic Imaging Camera

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.

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.

MPAC-V Verifier/Ultrasound Generator

The Megger Professional Acoustic Camera Verifier, MPAC-V has button controls to power on/off the MPAC-V, play/ pause an audio file, increase/decrease the volume and switch between the .wav audio files, pre-loaded onto the included MicroSD/TF card.

Key is the inclusion of a Verification sound file that automatically runs through the pre-set frequency bands that mirror the bands selected by the MPAC cameras when running in verification mode, automating the verification process.

In addition, sound files to replicate common partial discharge, using either 50 Hz or 60 Hz as the fundamental, help prove the MPAC cameras detection processor.

The MPAC-V supports a maximum signal output sampling rate of 96 kHz 24 bit, with a rated frequency range from 20 kHz to 48 kHz.

The product features a lightweight, sturdy and durable all-aluminium alloy case and can be powered by either the supplied USB-C 5 V power adaptor or four AA batteries.

• 8 audio files including the camera verification file, preset mechanical frequency files, white noise and gas leak, as well as samples of Suspension, Corona and Surface Partial Discharge – all at both 50 and 60 Hz
• Used to verify the operational status of the Megger MPACs (Megger Professional Acoustic imaging Cameras - MPAC128 and MPAC208)
• A dual-port USB-C power adaptor and USB-C cable are supplied as standard
• Designed to fit into the Megger MPAC cameras protective carry case

MPAC-TM640 Thermal Camera Module

The MPAC-TM640 includes a professional 640 x 512 thermal sensor. This unit is capable of generating high-resolution thermal images and will capture all the temperature data across the image. Through the MPAC208 user interface, relevant parameters can be set to improve the accuracy of the readings, as well as recording vital detail on the asset being measured. A x6 digital zoom is also available to aid pinpointing of issues.

The Thermal Modules are connected to the MPAC208 using a simple, keyed, USB-C port at the top of the camera. The MPAC firmware already supports the use of both modules, so no further set-up is required.

All thermal images and videos captured whilst using the MPAC-TM modules can be imported into the Analyst software, along with the acoustic data, for further analysis and detailed report generation.

• 640 x 512 thermal resolution
• Plug and play integration with MPAC208
• Simple USB-C keyed connection
• Thermal reporting using the Analyst software
• Robust aluminum housing
