YOU ASK:
ONE OF MY REGULAR INDUSTRIAL CUSTOMERS IS HAVING ALL SORTS OF PROBLEMS WITH THE COMPRESSED AIR SYSTEM IN HER FACTORY. THE COMPRESSOR RUNS ALL THE TIME AND IT’S COSTING HER A FORTUNE. SHE KNOWS THERE’S A LEAK, BUT SHE CAN’T FIND IT. I KNOW THIS ISN’T AN ELECTRICAL PROBLEM BUT I’D LIKE TO HELP. CAN YOU SUGGEST ANYTHING?
MEGGER SAYS:
Megger has the ideal product for that: our new MPAC128 handheld acoustic imager. Compressed air leaks (and other gas leaks) produce sound. Some of this sound you can hear, but most is ultrasonic – above the range of our hearing. The MPAC128 picks up this sound with an array of 128 microphones. It uses the signals from the microphones to work out the location of the sound source, which is shown on its built-in screen as a coloured cloud map. The MPAC128 also has a digital camera so what you see on the screen is a standard digital image with the acoustic image superimposed on it. That means you can identify the location of the leak almost instantly. You don’t even need to be very close – the imager can ‘see’ a leak up to 100 metres away, so you probably won’t need to climb any ladders. The MPAC128 works with any gas, and you can also use it to locate electrical partial discharge. Once you have one, you’ll wonder how you managed without it!
