Just out of clarification, I prefer my current role as I like the variety, I'm making no disparity to in house guys, we have very few adopters of PdM here in ireland and most of it is contracted with the exception of some large particle board plants and the one and only Oil refinery. There are A few plants including 2 I look after, who bought the gear and in house staff collect data and the vendor analyses he data and reports.

I evaluated a new French built meter/analyser with rules based system, wasn't a bad tool, it came in around half the price of the fluke, it took a novel approach to presenting the findings and even accommodated trending machines. The only let down was a frustrating User interface and ridiculously complicated machine set up procedure, (the method for interning data on it was a nightmare)

There are time s I wish ther was a more effective evaluation of lower urgency alarms on the system I currently use, I like the way the Azima system works form what I have heard, my time is at a premium and something that 'pares down' the inital route data set. I use note coded extensively when collecting tomassist in the inital vetting process, but can it be done better?

When I was beginning we wanted to buy a modern data collector, one of the vendor was very annoying with his "automatic diagnostic" Tools and how this machine would keep the expertise in itself instead of in the hands of the employee. I liked the idea as a new analyst without help but he was  so annoying that we went elsewhere. I hated how easy vibration analysis was in his eyes and my bosses hated that he was calling them every day (buying something expensive in a big company takes months).

About in-house vs consultants, Rusty made good points. The other mines/mills around me are very overstaffed. They are 5-6 employees while we cover more machines with 2 people here (and we could cover more). I LOVE being close to my machines tho, it's so nice to be able to go back to the machine when there is high 1x that I didn't notice while taking the data! Also we are a very isolated region, before hiring me they got quotes for vibration analysis in a sector that is about 10% of my job, the quotes (from big vibration companies) were more than my annual cost (2.5x my salary).

Another good thing about being in house: yesterday i wasn't able to transfer my data; I spent half the afternoon looking for the trouble and doing diagnostics just to find out that i had 2 databases that got full at the same time!!! Because I'm in-house, that time was paid [wink]

As far as effectiveness, an in-house program is the best way to go if you have good management, adequate resources, and good people who don't get bored and go to work in a different area of the plant (and the training/experience thing starts over with the next guy).  But in-house programs tend to be expensive because, IMO, they are over-staffed, and maybe have too much equipment.  Using someone like myself is probably about 80% as effective as having a good in-house guy, but I cost about 20% as much as an employee does (plus you can "fire" me anytime you want and I'll go away quietly).  So the cost-benefit ratio of an in-house program is not even close.  Now, if you hire a large reliability services firm, they are probably going to cost you a lot more than an in-house program, because they have a LOT of non-productive employees (CEO, COO, CTO, salesmen of all types, recruiters, HR people, etc, etc) who have to be fed, so the overhead has got to be insane.

Just my opinion, based on my experience.  Your mileage may vary. [smile] 

As been around the Pulp and Paper industry in Australia for most of my working life we are definitely not over staffed. This is why Vibe-Rater helps us out at our different mills every now and then and will be helping me out in the next month when I will be away. If we are properly staffed we would have been able to cover this ourselves. The previous paper company I worked at was similar and always took a long time to replace people and was even difficult to maintain the equipment as spending money was frowned on.

Back to the OP. Whenever I have seen these types of meters being used I am always concerned because the people using them always seem have this thought they will tell them all they need to know. This is most likely what they have been told by a salesman and so they do not have an understanding of where an instrument like that fits into the grans scheme of things.

LOL...a former boss of mine would go ballistic when the term "spectrum analyzer" was used, and not just because he preferred orbits and waveforms to spectrums.  His feeling was that a spectrum analyzer didn't analyze anything!  It was up to the technician to do the analyzing.  Many a time I heard him say they were spectrum displays.
