Good Day to all of you!
Can I possibly take vibration data in meter per second square (m/sec2) using an SKF CMVA65 collector? How to set up? I am (sort of) scrambling on this one because of an urgent request by our technical staff. I immediately make this post to hopefully get an idea incase I cannot make a set-up now. Please help me. Thank you very much! MRTA |

m/s^2 is the native units of most accelerometers.
Danny |

mM/S^2 (millimeter per second square) is basically standard and normally a RMS unit in Europe.
Mostly in the USA we work in g's 0-P. Cordially, Sam Pickens pdmsampickens@gmail.com |

well actually milimeters/sec is used for velocity, and meters/sec^2 for acceleration.
I have not seen accel express in milimeters/sec^2. 9.8 meters/s^2 is one g... e-mail me at steven dot schultheis at gmail dot com |

The question has been already answered but let me put it this way:
SKF analyzers can collect the vibration in acceleration measurements. The value of the reading in most cases is in g's (gravity). Have the value and convert it into the other units m/sec^2 by multiplying by 9.8. Example: the reading is 2 g rms in the analyzer is equivilant to 2 * 9.8 = 19.6 m/sec^2. Regards- Ali M. Al-Shurafa |

Steve,
I didn't see where anyone mentioned mm/s. 9800mm/s^2 is also equal to 1 g. You shouldn't be working late anyway  Danny |

|
Scroll up Sam mentioned mm/s^2

Isn't mm/s^2 millimeters per second squared or acceleration?
Danny |
||||
|
Yes, but it is not typically used, which was what I was trying to point out. (Obviously not very well...

Hi,
You can take acceleration in Gs and upload it to Machine Analyst. In Machine Analyst click right mouse button on spectrum and set the units to m/sec2. you will get the data in m/sec2. just try it out. Regards, Arun K |

DLI has a free units conversion program linked to:

Kind of like furlongs per fortnight per fortnight.
Danny |
||||
|
I don't think it has any units with that degree of Englishness.

I would pay serious money for a data collector that expressed acceleration in furlongs per fortnight per fortnight.
I would be posting spectrums here all the time just for the reaction...  e-mail me at steven dot schultheis at gmail dot com |

From now on I think we should express motor size in units of poncelets or pferdestarke.
Just a thought... John from PA |
||||
|
Now I've gotta figure out what those are.
Thanks John  Danny |
