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 from compressed air systems. The same instrument also detects dangerous partial discharges in high-voltage systems.
In many ways, the ear is better than the eye when it comes to detecting defects and shortcomings in many types of systems. However, sight is such a powerful sense in humans that we choose to trust our eyes more than our other senses. But technology comes to our aid when it comes to revealing a number of conditions where acoustics reveal more about the situation than the visual impression. This applies to two important but very different areas: leaks in compressed air systems, which can be pure energy waste and very expensive for industrial companies. The other is dangerous partial discharges, which often occur in high-voltage systems before more serious faults and outages in the high voltage – and which are therefore very productive to prevent.
Fluke is one of HIN's very strong agencies, and Fluke continuously works to develop new methods and systems to make the invisible visible to users, so that faults can be rectified or prevented easily and efficiently. The two closely related instruments ii900 and ii910 are excellent 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 locate – sounds that we humans are rarely able to hear. The sounds are converted into an image on the ii900/ii910's display, providing a visual representation of the sound with a clear marking of intensity relative to the surroundings. Fluke itself calls this 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 minimal energy waste in the compressed air system. Few people consider how much energy can be lost in a compressed air system, but nationwide, we are talking about many millions of kWh annually. By checking couplings and hoses with the ii900 during installation, leaks can be excluded immediately before they occur, and if there is a leak in the system, the Fluke ii900 quickly and easily detects faults 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. Prior to many faults and damage to high-voltage connections, so-called "partial discharges" occur, which produce an often inaudible whistling sound to humans. With its measuring range between 2kHz and 100kHz, the ii910 can display an image of partial discharges from a distance of up to 120 meters. It is a very effective service tool for regular maintenance of high-voltage connections, easy, fast, and safe.
The "sound images" on the Fluke ii900/ii910 are read on a capacitive 7" touch display with a 1280 x 800 pixel resolution. The instruments have three hours of operating time per charge.
