Is That A Vibration I See, Or Just Noise?

Hi everyone,

What do these machines have in common:

- Precision machine tools

- Centrifugal compressors and turbine blades

- Paper mill dryers

Very Low Noise Floor

How low is your analyzer's noise floor?

The answer is, they all have very low amplitudes of vibration. What happens if your vibration analyzer’s noise floor is higher than the amplitude of the vibration you are trying to measure? Simple – you can’t see the vibration because it’s hidden by the noise! This means that subtle yet significant changes in the vibration signature of a rotating or reciprocating machine such as a pump, turbine, or compressor may not be detected until it is close to failure.

Datastick customers and consultants have told us that they been able to see signals that were completely hidden in the noise level displayed by competing vibration analyzers – including those costing several times as much as ours. This has led us to the conclusion that our handheld vibration analyzer may provide the lowest noise floor among its competitors.

Cost Analysis Spreadsheet

Cost Analysis Spreadsheet

Sometimes it can be tough to explain how spending money now on machine condition monitoring can actually save money tomorrow. We’ve put together a Cost Analysis Spreadsheet so you can have a great tool to analyze the costs of an unscheduled breakdown versus the benefits of machine condition monitoring. Simply substitute your own numbers. It’s especially useful when talking with others in your organization.

Please go to this page, fill in a form, and we’ll be happy to send it to you (or just call us)!

Your vibration measurement data is yours, isn’t it?

Hi everyone,

You would think that every company that makes a vibration analyzer would agree that your measurement data is your own. But some make it incredibly difficult to get your data out of their system. At Datastick we are not like that. We have our own technology that makes great products, but where your data is concerned, we support exporting to open formats. The principle by which we operate is:

Your measurement data is yours.

The Datastick Spectrum software suite exports measurement data to the open standard of XML. “XML” stands for “Extensible Markup Language” and enables communication between different systems that would otherwise be unable to communicate.

XML Open Format Data

Thus, you can import the measurement data generated into almost any database system that accepts and processes XML. We do not do any encryption or copy protection of measurement data generated from the Datastick Spectrum software suite.

It is our opinion at Datastick Systems that it is you who put labor into taking this measurement data. Thus you own the measurements and you have the right to do whatever you want with them. We support this opinion by exporting into the open standard of XML.

Of course, we also make sharing your data with colleagues easy through our Excel-compatible PC software, and fast creation of reports in Excel, Powerpoint, and Word.

Machine maintenance. The buck stops where?

Hi everyone – They say success has many parents whereas failure is an orphan. The whole team can take pride in a smoothly running system. Yet when unexpected breakdowns occur, those same teammates will wonder who let them down. Shouldn’t somebody have seen what was coming? If that job or “hat” is unassigned, then who could have been in a position to see what was coming? After all, there is always at least some indication – could it have been observed? After a breakdown, the urge to find someone to name can be almost irresistible.

“The buck stops here.” What does that mean? Well, here is the story behind the slogan. It started with the phrase, “passing the buck,” which means to pass responsibility for something to someone else.

"The buck" designates the dealer in poker.

The expression “Passing the buck” came from the game of poker. A button or marker was used to indicate the person whose turn it was to deal cards. If a player did not wish to deal the cards, he could pass the responsibility by passing the “buck,” as the marker came to be called, to the next player.

“The buck stops here.” This was a sign on the desk of Harry S. Truman, who wore the “hat” of US President. When he left office, he said, “The President – whoever he is – has to decide. He can’t pass the buck to anybody. No one else can do the deciding for him. That’s his job.”

How does this apply to machine maintenance?

I think the answer to this question is another question: Who could have watched for indications that, if observed, could have avoided that failure?

Could it be you? And what would you need to do it?

The calculation of cost of condition monitoring instrumentation versus downtime has already been done by many (see below for how to do it for your machine). For most machines, there is no comparison. Yet, the “bean counters” (slang for the financial guys) say we can’t afford the cost just now (but somehow the cost of downtime or sudden repairs does get covered), so the buck could be passed to them.

Or the buck could be passed to a manager who, for reasons unknown, failed to approve the purchase of a $30,000 vibration analyzer and a maintenance contract of $7,000 per year.

But don’t be too surprised if the buck finds its way to you, fairly or unfairly.

The point is, finding a place to pin the buck won’t fix a machine that rattled itself to pieces. Really, it’s better to have the tools to avoid breakdowns than a great system for passing the buck around.

Thankfully, you probably don’t need a $30,000 piece of equipment and a $7,000/year maintenance contract to institute an effective vibration analysis program.

You could just decide to take it on and “wear the hat,” that is, be the one who does the condition monitoring or who insists it gets done effectively, even if you’re not in the pass-the-buck circuit.

Or you could wear the hat of helping educate managers and financial people on the real cost of failing to monitor the indicators. Our Cost Analysis Spreadsheet can help (it has its own category on this blog page).

You can just say: “The buck stops here” and “I can do this.” We can help.
