Fluke II910 Precision Acoustic Imager



Fluke II910 Leaks in compressed air, gas, steam and vacuum systems hurt both production uptime and the operations bottom line.

With Fluke While most manufacturers know that these types of leaks exist, it has been too time consuming and tedious to address them until now. With the Youtube ii910 Precision Acoustic Imager and minimal training, your maintenance technicians can begin checking for leaks during their typical maintenance routine-even during peak operation hours.

Fluke II910 acoustic imagers let technicians see sound as they scan hoses, fittings, and connections for leaks. The II910 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.

Finally a better way to detect compressed air, gas, steam and vacuum leaks using Fluke System. Plus, the II910 provides increased sensitivity to detect leaks that are smaller or farther away.

Detecting Partial Discharge (PD)

The invisible threat you can now see

Fluke II910 Partial Discharge is a very serious issue that you would like to be able to monitor quickly and easily. Whether you are inspecting insulators, transformers, switch gears 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.

Product Features:

  • Partial discharge detection detects Corona and Partial Discharge (PD), even when there is no direct line of sight
  • Cut costs and save energy everyday by taking the guesswork out of finding and fixing partial discharge
  • High sensitivity allows users to detect PD at earlier stages, enabling condition-base maintenance and planning service of equipment (vs preventive replacing/servicing/cleaning)
  • SoundSight™ technology translates sounds into visual representation so that users can easily scan and quickly locate problem areas
  • Ease of use allows untrained users to detect, locate, and assess severity of Partial Discharge, Corona Discharge or Gas/Vacuum leaks, easier, faster, and more effectively than existing Ultrasonic Tools, by using visual images to better pinpoint and report PD, Corona or Gas leak
  • PDQ Mode™ provides relative severity of discharge, which provides information to users on whether action may or may not be needed after PD has been detected
  • LeakQ™ estimates size and cost of leak, including new distance-estimation feature and 1-10 LeakQ™ severity index
  • Images can be uploaded online to generate leak reports including leak size and cost estimation
  • Video recording up to 5 minutes can capture behavior of identified problem or capture larger environment to review at later stage potential spots to review in further detail
