Been windy the last couple of days and I left my flag up until mother nature decided it needed to be on the ground. I have a flag bracket that was secured to a facia board with three screws. It appears that the force from the wind on the flag caused the screws to loosen/backout, which then...
I was at a conference last week and we were discussing a vibration problem on a 2 speed motor / fan. The motor experiences a vibration spike when the speed is changed. The vibration is observed by shaft relative (proximity) probes. One of the questions posed, was is this "real" vibration or...

I received a spreadsheet that has data from numerous motors. The motor ID is in 1 cell in column C. There are anywhere between 6 and 20 rows of data associated with the motor ID. I would like to fill in the blank cells in column C as shown below (Current versus Desired). How can I do this...

I want to expand my working knowledge of statistics in regards to analyzing predictive maintenance (PdM) data, such as vibration or oil analysis results. I'm familiar with the basics of setting alarms at +/- multiples of standard deviations, but I would like to learn more about statistics in...
Does anyone have experience with using underwater accelerometers on vertical pumps? Is the data noisy? Were you able to diagnose any machinery problems from the data?
Thanks!
