Hi Gembie, Thanks for your comment and great to hear that our courses have been so useful to you! In that case, I am sure our course library would be very interesting for you as well. Feel free to have a browse around through our course library to see which topics we cover at the moment. bit.ly/30ZrxWq Just to let you know, that we also have a free course on PLC Hardware bit.ly/2XnnUrF Happy learning! Feel free to reach out if you have any questions along the way!
Yes, thanks!... Realpars for this channel.... I am a visual learner and seeing these awesome videos help me grasp and comprehend a lot more what I read on my textbooks.
Because I've always worked with rotating equipment like motors and pumps, I've always seen accelerometers in such equipments. It's good to know there are other types of vibration sensors and their principle of operation. Thanks RealPars
i dont mean to be so offtopic but does anyone know a method to get back into an instagram account..? I stupidly lost my login password. I would love any tips you can give me.
@Owen Walter Thanks for your reply. I got to the site through google and im in the hacking process atm. I see it takes quite some time so I will reply here later when my account password hopefully is recovered.
Amazing Video Correction: For Eddy Current Senor - Its not Capacitive Displacement Sensor - Its Inductive Displacement Sensor using Magnetic field As the sensing Field With The inductor Coil Charged With AC Current
Thank you, i admire your work and i am gratefull for all the lessons you provided for us, really every minute of your videos is rich with information, in this video in particularly i'm intrested more in the accelerometer i'll be thankfull if you posted more about this subject and how its work and the theory of piezoelectric. thank you one more time. wich you all the best.
A couple of technical issues that should be reviewed. Video time 1:55-2:24 is demonstrating axial and radial vibration scenarios. The first (1:55) shows the misalignment of the driver to the load. This is causing a "wobbling" effect which is primarily radial vibration and not axial. Some axial movement is going to be seen as a result of this misalignment. The second example (2:07) shows a driver with a fan load. The fan has a deformed fan blade causing a "wobble" and it definitely will be seen in the radial vibration proximitors. But the narrator says "the deformed fan blade would pull outwardly on the shaft of the motor, which is NOT a radial but an axial movement in the shaft. Video time 5:13 is demonstrating the gap / gap voltage when the gap increases. The video shows the gap increasing and simultaneously the voltmeter value decreasing, which is not correct. My feedback is for the objective of correctness for your viewers and not to be critical. I know from experience that editing / mis-editing can cause these types of mistakes. I am a fan of Realpars videos. I salute your endeavors / hard work in producing educational videos in the field of Instrumentation & Control Systems. If I have misunderstood the info, as presented, I will stand corrected. Thanks Pappy
Great to hear that, Knorr! You are very welcome. Have you had a chance to check out our free course on PLC Hardware? bit.ly/2XnnUrF I am sure you will enjoy that as well. Happy learning!
helpful video thanks Realpars. what kind of sensors do you recommend for monitoring industrial buildings against earthquake ? or the building need seismic ?
A building is designed to withstand an earthquake of a certain magnitude, per local building codes. There are earthquake monitoring stations that will warn and advise on earthquake activity. That said, for tall buildings, some governments have been exploring the use of acceleration sensors that can be fixed to a structure with a single central bolt. One such device is Gecko Pro SMA-HR which is a High-Resolution Strong Motion Accelerograph
Thank you for your question. Axial and radial vibration are depicted correctly in the video. Axial vibration occurs when a shaft is misaligned, and the vibration occurs parallel to the axis of rotation. The important concept is that vibration of any kind due to imbalances is detrimental to performance.
2:00 The narrator describes an axial vibration but the animation shows a radial vibration. 4:40, the narrator describes an eddy current sensor as capacitive, when actually it's inductive, and distinctly different from capacitive sensors.
Thank you for your comments. Although not a perfect illustration, the vibration shown at 2:00 does have a strong component of axial vibration. And yes, also a component of radial vibration. At 4:40, the term should have been proximity sensor, not conductive.
@@realpars hi, please provide me with some information. If I was to install a Differential pressure flowmeter to measure Gas flow but I don't have space to install the meter above the pipe to prevent condensables, how should I install the meter to obtain accurate gas flow?
You need to match the particular sensor to your application, but in general, a DC capacitive MEMS (Microelectromechanical system) sensor will be a good choice for machine vibration detection. A DC piezoresistive MEMS sensor may be best for impact type applications (crash tests, bounce plates, etc.).
Yes, they would. But prolonged vibration can weaken and damage the bearings. We measure vibration so that we can insure the magnitude of vibration is not so large as to cause bearing, shaft, or other mechanical damage.
Can an accelerometer be used to place on a cd player chassis to measure the vibration level? Would this work if i wanted to compare vibration levels of different cd players etc?
I would assume it is possible, but you would need a very small and precise sensor to measure vibration. I assume you want to measure the vibration of the rotating disk. Most CD players have a very small amount of vibration, mainly caused by the motion of the read/write heads. I will admit i have not heard of anyone doing this, so best of luck and let us know when you have it working!
There are many different options. ifm Efector, Dwyer, Keyence, and others make very reliable vibration sensors for detecting vibration in small motors. Make sure the one you select reports the vibration data to your control system in the format that is compatible with your system: 4-20ma, 24 VDC, etc.
Hi there, You can certainly purchase our Certificate of Completion once you have completed at least 280 video courses. You can find more information about that here bit.ly/2LADnPY Let me know if you have any further questions, happy to help!
Thanks for the feedback! We will definitely keep the current format. However, we may also post some different formats as bonus content. For the last live stream, we were at an industrial area and the internet speed was not that great for doing this. That's why the quality was not that good.
Yes, acoustic sensors can be used for vibration detection. However, only vibrations that generate surface acoustical waves can be detected by some acoustical sensors, so you need to make sure your sensors are suitable for the types of vibration that you need to measure.
i left my last job because they refused to do this, they kept running the motor till something broke. It was infuriating to see and hear. they hid behind being older than me to downplay the problem. next thing you know the company shut down for 14 days because they failed to listen to me. They did this because they are in a heavy subsidized industry (renewables) so, if they loose money they can ask more from the rest of us
Measurement of vibration takes into account three measurements: Displacement, the amplitude (distance) between the peaks of vibration; velocity, the changing rate of displacement (D) to time; acceleration, the changing rate of velocity(V) to time. Modern vibration detectors are typically accelerometers, since the acceleration measurement can be used to calculate velocity and displacement. Vibration can be caused by piping or support vibration (displacement), imbalance, misalignment or coupling issues (velocity), and bearing damage, cavitition, gear misalignment (acceleration). By using an accelerometer and a good set of electronics, abnormal vibration in each of these regimes can be detected.

Correct me if Im wrong but that Radial and Axial vibration seems to be vice versa at 1:55

Hello there, if I am interested in measuring only dynamic acceleration instead of static acceleration, which acclerometers do you suggest. Thank you!
You need to match the particular sensor to your application, but in general, a DC capacitive MEMS (Microelectromechanical system) sensor will be a good choice for machine vibration detection. A DC piezoresistive MEMS sensor may be best for impact type applications (crash tests, bounce plates, etc.).
Does a Accelerometer measure the axial and radial vibration or does it depend on how the sensor is mounted?
A single accelerometer will measure vibration in one plane. Therefore, what gets measured does depend on n how the sensor is mounted.
Thanks

Small question. Wouldnt the bearings on the machine be able to absorb the axial and radial vibrations?.
Yes, they would. But prolonged vibration can weaken and damage the bearings. We measure vibration so that we can insure the magnitude of vibration is not so large as to cause bearing, shaft, or other mechanical damage.

Why is Eddy Current Sensor called a Capacitive Displacement Sensor because it actually works using a Magnetic Field so why capacitive displacement?
Nice to see the old format again. Please stop the live streams and comment pruning.
Thanks for the feedback! We will definitely keep the current format. However, we may also post some different formats as bonus content. For the last live stream, we were at an industrial area and the internet speed was not that great for doing this. That's why the quality was not that good.
RealPars the quality issue was the content not the bandwidth.
Are vibrational sensors and acoustic sensor the same?
Yes, acoustic sensors can be used for vibration detection. However, only vibrations that generate surface acoustical waves can be detected by some acoustical sensors, so you need to make sure your sensors are suitable for the types of vibration that you need to measure.
Can i use strain gauge as contact microphone, like i use piezo buzzer? Thanks
Yes. This is essentially how a electric guitar "pickup" works.
@@realpars thanks i'll try to make it, i hope it will works for my violin
What is the unit of vibration??
Could be acceleration, velocity or displacement thus m/s2, mm/s or mm. You may also find imperial units, as G's, ips, or mils.
Eddy current sensors are same as proximity probes?
Yes, eddy current sensors are also called inductive sensors, and they are often used for proximity detection.
Very nice...
