Leaks in compressed air, gas, steam and vacuum systems hurt both production uptime and the operations bottom line.
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 Fluke 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.
The ii910 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.
Finally a better way to detect compressed air, gas, steam and vacuum leaks. Plus, the ii910 provides increased sensitivity to detect leaks that are smaller or farther away.
The invisible threat you can now see
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.
