Hello,

Does anybody have first-hand experience with this product?

Fluke ii900 Sonic Industrial Imager: https://www.fluke.com/en/product/industrial-imaging/sonic-industrial-imager-ii900

For those who are not familiar with the product, it is a portable sound mapping camera that superimposes the sound source on the visual image to identify the source of the noise. Similar concept to the thermal imaging camera.

There are a couple of videos on youtube also.

Vendors are welcome to comment.

  1. What applications it really works well with?
  2. What applications it doesn't really work well with?

My environment is industrial plants (power, chemicals, O&G), Classified Areas with harsh temperatures and humidity.

I have seen this device doing the rounds online and its sold as being user-friendly and needing no skills to use......always suspicious, it seems limited to acoustic emissions so Air leaks and possibly corona/arcing/tracking testing but it does not seem to have a contact testing option.

Most other Ultrasound instruments whether they are UE systems or SDT can do air leaks, steam traps, bearings, valve inspection as well as electrical coronal discharge testing.
On top of that the price these are quoting for in Ireland you can buy the full feature top of the range Ultraprobe15000(UEsystems) or an SDT270 which are far more versatile tools.

To be honest I haven't had a lot of luck using ultrasound tools like the UE Systems ultraprobe.  Maybe I never spent enough time with them.

Someone else at our site is arranging for a salesman to come to pitch this device Fluke ii900 to us.  I'm not sure yet what it costs or who would be paying for it if we buy it (maybe the fluid leak detection guys). 

Here is a demo I found on youtube. 

This device displays an image showing color-coded magnitude of sound in an adjustable frequency band (Fmin and Fmax independently adjustable between 2khz and 50hz). 
If you look around 3 minutes into the video, you can see on the right side there is a live plot of the spectrum of the noise of the salesman talking (I'm not sure what part of the image that represents, maybe the whole thing). 

We spend a fair amount of time chasing noises in noisy areas.  I'm guessing the relevant audible range is maybe 100hz up to 20khz. This might be an interesting tool although it would have been nice if the Fmin was adjustable below 2khz.  Also, maybe on some rare occasions a sound image of rotating equipment would reveal something useful? 

What do you guys think: could this be a useful tool in the toolbox for rotating equipment... or leave it to the leak detection guys?

El Pete,

There are several Acoustic Camera products available for the audio frequency range. 

Mikado - The handheld Acoustic Camera

100 - 11 kHz

From <https://www.acoustic-camera.com/en/products/microphone-arrays/mikado.html>

 

Norsonic Acoustic Camera

100 - 20 kHz

From <https://web2.norsonic.com/product_single/acoustic-camera/>

 

BK Connect Acoustic Camera

From 100  - 7 kHz to 100 - 20 kHz

From <https://www.bksv.com/en/products/data-acquisition-systems-and-hardware/general-purpose-analyzer-system/Bk-Connect-acoustic-camera-9712>

 

ACOEM 01 dB Acoustic camera

10 - 24 kHz

From <https://www.01db.com/our-solutions/our-products/acoustic-cameras/01db-noise-inspector/>


These are typically a tool (expensive one) for a Noise Control Engineer.

Thanks Walt. Wow, I never realized this was a product category (acoustic camera).  Apparenlty there's a lot out there.  Some of those would definitely be better than the Fluke thingy for my purposes, but our guys looking for fluid leaks may not like the 25khz or so upper limits.   With the adjustable Fmax and Fmin like they have on the fluke, a single device could in theory do both things (troubleshoot audible noise and look for leaks), but unfortunately they didn't give a low enough range on the Fmin.

I'll probably wait and see how the sales presentation works out and who's going to pay for this thing.

I am looking at having this brought in for a demo.  Want to see if it works for vacuum leaks.  Will update what I find.

Ron,

"Want to see if it works for vacuum leaks." As you may know, vacuum leaks can be more difficult to measure with sound/ultrasound compared to positive (above atmosphere) pressure leaks. If you do have a demo of the Fluke system, perhaps you can compare to typical ultrasound meter (SDT or UE) or other leak test methods.

I am curious how the multi-sensor Fluke system compares to a single focused microphone on a meter. The display analogy is like a thermogram compared to a spot IR meter. My questions would be whether the Fluke can detect smaller/same leak at the same distance, is less affected by background sound (same direction and  reflections), and data logging/routes. What feature added together offer good value compared to a meter?

I had my hands on it at a conference. It was pretty impressive. I second the useful only for air leaks and possible electric faults. I asked the question about airborne bearing measurement. He said they were working on that next.

We purchased one of the Fluke cameras last fall. I have a fair amount of time on it. Been impressed so far. It seems to be pretty sensitive and the array of microphones does a good job of triangulation for the leak location. You can take additional location pictures to add the leak picture. Helps eliminate leak tags and finding said tag. I have picked up on some motor bearing noise from about 30 ft that was audible once I was next to the motor. So the jury is still out on that.
