Don't let the money drain out
Fluke is one of HIN's strongest agencies, and with Fluke's ii900/ii910 testers, the industry now has access to a solution that effectively reveals where air – and money – is leaking out of compressed air. The same instrument also shows the dangerous partial discharges in high-voltage systems.
In many ways, the ear is better than the eye when it comes to detecting errors and defects in many types of systems. However, vision is such a strong sense in humans that we choose to trust our eyes more than the other senses. But technology comes to our aid when it comes to revealing a number of conditions where the acoustics give more clues about the condition than the visual impression. This applies, among other things, to two significant but very different areas: These are leaks in compressed air systems, which can be a real energy drain and very expensive for industrial companies. The second is the dangerous partial discharges, which in high-voltage systems often occur before the more serious errors and failures in the high voltage – and which are therefore very productive to prevent.
Fluke is one of HIN's very strong agencies, and Fluke is continuously working on developing new methods and systems, that of making the invisible visible to users, so that errors can be corrected or prevented easily and effectively. The two closely related instruments ii900 and ii910 are very good examples of this. The instruments are a kind of "augmented reality" of our hearing, and up to 65 built-in microphones can very effectively detect - and place - sounds that we humans are rarely able to hear. The sounds are transformed into an image on the ii900/ii910's display, so that you get a visual representation of the sound with a clear marking of intensity in relation to the surroundings. Fluke itself calls the concept "Sound Map™".
With the ii900 you get an instrument that is ideal for detecting leaks in compressed air systems. It ensures maximum uptime, function when needed and a minimum of energy waste in the compressed air system. Few people think about how much energy can be lost in a compressed air system, but nationally we are talking about many millions of kWh annually. By checking couplings and hoses with the ii900 during installation, you can immediately rule out leaks before they occur, and if you have a leak in the system, the Fluke ii900 reveals errors easily and quickly by measuring center frequencies between 2kHz and 52kHz at distances up to 70 meters.
For service and prevention of breakdowns, damage or even accidents in the high-voltage sector, the Fluke ii910 works in much the same way. Many faults and damage to high-voltage connections are preceded by so-called “partial discharges”, which produce a hissing sound that is often inaudible to humans. With its measuring range between 2kHz and 100kHz, the ii910 can display a picture of the partial discharges from up to 120 meters away. It is a very effective service tool for regular maintenance of high-voltage connections, easily, quickly and safely.
The Fluke ii900/ii910 displays the “sound images” on a capacitive touch 7” display with a 1280 x 800 pixel resolution. The instruments have a three-hour operating time per charge.
