The videos are absurdly helpful. Helping me set up maintenance plans and efforts for multiple clients whos facilities we maintain electrically. Thank you!
00:46 haahaahahahahaha I use these videos for my graduation work, finally there was an unexpected reason for me to laugh, and at the same time useful, special thanks from Azerbaijan
Hello Adash! It seems like you're using "cold welding" in order to fix the measuring point at 2:11. So my answer is simple - how does the "cold welding" layer affects on vibration level values? Do your measurements become more precise? And does it affect your high frequency vibration (acceleration)?
It is actually not a cold welding. It is epoxy glue which has the properties like a metal when dry. Your measurements will be repeatable and high frequency bearing signals will be transferred better than using finger tip or magnetic base for curved surfaces.
2:33 Can't we put the sensor on one of the two bolts that secures the bearing housing together? But if we do so, can we get an accurate reading since the bolt head appears smaller than the surface of the sensor?
That is not a good idea. Yes, bolt is smaller than the magnetic base of the sensor. These bolts are not ideally flat and the sensor will rock / swing on them. More over, the bolt actually behaves as a spring and it will damp a lot of high freguency (bearing) signals.
This is very general question. There is endless types of machines and their applications in particular industries. Every machine or machinery set (e.g. motor with gearbox and pump) generates vibrations on specific frequencies according to their construction and other parameters such as speed, load etc. There are speed frequencies, gear mesh frequencies, bearing frequencies, drive belt frequencies to name a few. Therefore there is no general answer to your question.
When measuring vertical, horizontal, and axial vibration, do you compare each measurement to the maximum limit? or do you calculate some sort of resultant or average then compare it to the max?
Vibration analysis on gearboxes will be surely more difficult due to more shafts, gears etc. Ideally you should measure on each bearing house of each shaft if they are accessible.
See this video from 3:28 about magnetic base for curved surfaces. The idea is to measure as close to bearing you can in order to get good signal from it. And to have good information about mechanical state of this part of the machine.

The way you explained in all your videos is quite phenomenal. Loved it.
Glad to hear that

Thanks for this very informative video.
Prefect and to the point.

Very useful for beginners
Very nice 👍👍👍👍 sir

@@AdashCompany Thank you sir. Best regards from Malaysia!
Thanks for sharing
thanks for the help
Do you have info on frequencies and what they mean
This is very general question. There is endless types of machines and their applications in particular industries.

Great!
Keep it up team Adash!
Great video! Thanks a lot!
Great! Please keep uploading this type of vedios
I almost stopped the video at 0:50. Haha

This is difficult question as there is no general maximum vibration limit. It depends on machine size, type, speed, load and other aspects.
I use of spm equipment for measure vibration
Ok, thanks for information.
thanks a alot
where do we need to place the tri-axial accelerometers in case of monitoring a gearbox, please help!?
Vibration analysis on gearboxes will be surely more difficult due to more shafts, gears etc. Ideally you should measure on each bearing house of each shaft if they are accessible.
if the motor doesn't has point of mesure, where can i mesure?

Hi
Team your Vibration monitoring system is Compliance withAPI617
Sorry, our systems does not comply with API617. But it does not stop them to be great vibration monitors being sold worldwide.
