NL Acoustics PL001 Industrial Ultrasonic Camera

NL Acoustics PL001 Industrial Acoustic Imaging Camera

The stand-alone NL Acoustics PL001 Industrial Ultrasonic Camera is an intelligent device for pinpointing partial discharge in high voltage and medium voltage systems, and air leaks in compressed air system (using acoustic beamforming method).

What is Acoustic Beamforming?

Acoustic beamforming is a technique for measuring sound spatially from a specific direction instead of measuring all the sounds in an environment.

Measuring sound from one direction enables:

  • Localizing sound sources
  • Measuring a signal even when the surrounding noise level is higher than the desired sound source signal

The most basic principle for acoustic beamforming relies on time differences (delay-and-sum): Sound signals arrive at different microphones at slightly different times. The microphone signals are then delayed and summed. This:

  • Emphasizes the sound coming from the desired direction
  • Minimizes the sound coming from other directions

In conclusion:

  1. Acoustic beamforming makes leak localization possible, meaning that acoustic camera can pinpoint a leak’s location
  2. Acoustic Beamforming requires multiple microphones (124 microphones), which also translates to better acoustic performance of the device

Why Does the Ultrasonic NL Camera PL001 Have 124 Microphones?

The more microphones will lead to improved acoustical performance, which entails:

  • The possibility to find smaller compressed air leaks thanks to increased sensitivity
  • Scanning larger areas more quickly from a distance thanks to increased maximum detection range
  • More reliable fault location thanks to the better resolution of more precise acoustic imaging

Ultrasound NL Camera Leak Detector vs. Conventional Leak Tools

The Ultrasound NL Camera Leak Detector can pinpoint a leak’s location thanks to its multiple microphones, whereas conventional ultrasonic tools with one (directive) microphone cannot.

Benefits of the NL Camera Leak Detector Shortcomings of conventional leak tools
  • Leak localization
  • No leak localization
  • Industry-leading leak detection and analytics
  • Limited or no leak analytics
  • More accurate thanks to wide frequency bandwidth
  • Less accurate due to narrow frequency bandwidth
  • Automatic leak recognition does not require the use of headphones
  • Manual leak recognition requires the use of headphones
  • Intuitive user interface that requires minimal training
  • Require lengthy training
  • Free cloud service and offline software options
  • Limited software options

Partial Discharge Detection Methods

In fact, there are three nondestructive partial discharge detection methods which you may find the following list.

  • Acoustic methods: Conventional ultrasonic probes, and acoustic cameras: They can be used for PD detection; but are very limited for this purpose.
  • Thermal cameras (IR): They have some limitations for PD detection. For example, they only certain PD types, typically at a very late stage.
  • Ultraviolet cameras (UV): They have some limitations in PD detection, such as the requirement for a direct line of sight.

The Ultrasonic NL Camera P001 not only includes unique features; but also it’s equipped with an advanced intelligent analytics software using which it can evaluates how critical the detected partial discharge is; and advises the user (in 24 languages) what to do about them.

The NL Cloud analytics software which accompanies the Ultrasonic NL Camera P001 can determine the type of partial discharge; but now the AI-powered machine learning-based algorithms, it can also assess the severity of the partial discharge. In addition, to avoid fatal breakdowns and downtime, the software recommends what actions to take. If you want to know more about the Partial Discharge Severity Assessment, please click here.
