FLUKE ii910 Precision Acoustic Imager

Discover the simple way to quickly detect, locate & analyse partial discharge (PD) with confidence.

Partial discharge is a very serious issue and often difficult to find.  Whether you are inspecting insulators, transformers, switchgear or high voltage powerlines you need to be confident you can spot a problem in time to fix it long before it becomes catastrophic.  Partial discharge that goes unchecked can cause blackouts, fires, explosions, or deadly arc flashes.  There is a significant monetary risk of downtime.


What is different about the FLUKE ii910?

Compared to the FLUKE ii900

Frequency Range:

  • ii900: From 2 kHz to 52 kHz
  • ii910: From 2 kHz to 100 kHz

Detection Range:

  • ii900: Up to 70 meters (230 feet)*
  • ii910: Up to 120 meters (393 feet)*

*Depending on ambient conditions

The FLUKE ii900 Series enables you to detect leaks in compressed air, gas, steam and vacuum systems hurt both production uptime and the operations bottom line.

Knowing these leaks exist isn‘t new... but an efficient way to detect them is!  Minimal training is required so your maintenance technicians can begin checking for leaks during their typical maintenance routine, even during peak hours of operation.

The ii900 series acoustic imagers let technicians see sound as they scan hoses, fittings, and connections for leaks. Its built-in acoustic array of tiny sensitive microphones generates a spectrum of decibel levels per frequency.  Based on this output, an algorithm calculates a sound image, known as SoundMap that is superimposed on a visual image. The SoundMap is automatically adapted depending on the frequency level selected so that background noise is filtered out, making it incredibly simple to detect compressed gas leaks. 

The FLUKE ii910 provides increased sensitivity to detect leaks that are smaller or farther away.


▶ What‘s The Difference FLUKE ii900 & ii910?:


FLUKE ii910 Partial Discharge Detection

The invisible threat…now you can see

Partial Discharge (PD Detection) is a very serious issue - To monitor quickly and easily is important.

Whether you are inspecting insulators, transformers, switchgears or high voltage powerlines you need to be sure that you spot a problem quickly and early.

Partial discharge that goes unchecked can cause blackouts, fires, explosions, or death from arc flashes. In addition to the danger that partial discharge poses to human lives and the environment, there is a significant monetary risk of downtime. Having equipment go down can cost millions of dollars per hour of downtime.

The FLUKE ii910 Precision Acoustic Imager is the perfect tool for high voltage electricians, electrical test engineers, and grid maintenance teams that are constantly inspecting and maintaining power distribution and industrial high voltage equipment. The ii910 provides a safe quick and easy way to detect and locate partial discharge in order to maintain high voltage equipment and prevent catastrophic events. With the SoundSight technology the ii910 translates the sounds that it hears into a visual representation so that you can quickly locate problem areas. The higher frequency capability of the ii910 allows for earlier detection to facilitate early maintenance planning and is why the ii910 has a frequency range of 2-100Khz.



FLUKE ii910 Applications:

  • Detect partial discharge early allowing for proper scheduling of maintenance, increasing uptime
  • Quickly and easily scan areas to find potential problems
  • Detect and analyse partial discharge from a safe distance
  • Cut costs and save energy everyday by taking the guesswork out of finding and fixing partial discharge
  • Plus detect leaks in compressed air, gas, steam and vacuum systems
