These videos have helped me tremendously with understanding the basics of vibration analysis! And I will be continuing to watch before I take my certification!
it’s a very nice presentation, and very informative. Helpful to brush up my skills in vibration testing both performed in the DCS testing facility and at project site. Thanks for sharing such a nice video.
Hi Suwatchai K - To the best of my knowledge, most modern systems maintain the convention of blank-bright with forward precession regardless of the nature of the trigger. I have to confess that I have not polled every manufacturer. As for rising/falling edge, my understanding is that this is also handled differently in digital systems versus oscilloscopes - but I will look into this. (I am traveling right now so it will take a few days.) Thanks for your comment.
***** Robert (Bob) Eisenmann co-teaches our Category IV course and we have discussed this issue at length. To the best of my knowledge, if you go back to the traditional theory, what you say is correct - and that's the way it worked on an oscilloscope. And that is why it is documented that way in those two references. However, that convention has been superseded in many modern digital systems so that it is always blank-bright regardless of what the keyphasor is detecting. The main reason, as I understand it, is so that you can always quickly identify reverse precession. I wish I had Don Bently's (and co-author's) book - I am sure it was clearly stated in that reference.

Sir, For 210Kg flywheel, dia of 700Mm, dynamic balance for 4000 rpm,before balancing unbalanced grams R1=40grams,R2=50grams , after balancing R1= 0.49 grams,R2=0.51 grams , vibration is less than 2.61 is these acceptance as per standareds
Hi Preethesh, this would be a great question to ask the thousands of CBM and Reliability connect professionals on mobiusconnect.com. You can post your question on the forums or on the live feed!
Thank you, Jason! Very informative video and easy to watch as well!
excellent overview of vibe analysis and what each probes provide you.. highly recommend it to anyone who looks at the vibe data. Beautifully explained

I watched it so many times. Still everytime there is something to learn..
Awesome, just awesome. Tons of useful and practical information. Gives me a direction and destination with my project!
I am grateful for this presentation ,it helped me a lot to clear very basics of orbit and centers.Thank you very much Mobius institute.
You are Guru of Vibration Analysis..
Thank you for your kind words!
One of the greatest lessons I have learned on rotor dynamics. Thank you so much!

Superb presentation . You gave us lot of info. Thank You very very much....!!!!!!!!1
Great presentation. Clear as crystal and improve the knowledge a lot. Looking forward the other presentation for rotor dynamic presentation😊😊👍🏻👍🏻👍🏻
Thanks, great presentation.
thanks so much!
So much knowledge in video. Simulation softwave is very helpful.
Many thanks for providing this explanation.. very good simulation!
Nice. Thank sir
Excellent explanation 👌
Great, many thanks, it is helpful
Very Nice presentation.

Excellent & very useful
thanks jason, it's so usefull, keep it up !!!
All are nice presentation but some detail required in rotor dynamics
Good explanation, thanks for sharing.
Please suggest how to measure the Centrifugal force of round metallic vibrating tube
thank you it is very helpful
Glad it helped!
I'm wondering why vibration is handle ALWAYS as a negative matter!!!
very usefull, thanks
Very NIce
Awesome
