For sometime RMS have been carrying out a Motion Amplification Introduction Day with RDI Technologies camera technology, this is one of the best ways to evaluate this exciting new technology. Our introduction days have been very successful as the value can be shown quickly when used on the right application.
Typical agenda as follows:
Before the onsite visit a general overview of MA is given via a virtual call.
08:30 – arrive on site inductions etc straight on to plant collecting MA data on select assets.
We suggest 4 – 6 assets could be looked at maybe more, different applications good, rotating equipment, structures pipework, slow speed etc. As a rough guide amplification works best on 1 & 2 x vibration problems, asset needs raised vibration levels above 4 mm/sec to visualize motion or low frequency problems with raised displacement levels work well. If low levels present camera will not see much when amplifying so right equipment has to be selected for testing.
13:00 – process and analyse data prepare your videos for presentation
14:00 – technical presentation on MA to a booked conference room. (with invites sent out to key stakeholders, engineers, managers, fitters etc CM guys too)
- Presentation takes 45 mins to 1 hour
- MP4 MA Videos from the day are supplied to client.
How is the scope of this technique in screw type air compressors?
We recommend the IRIS MX system for this. With the MX you can collect data up to 29,000FPS or 14kHz Fmax. We have used the technology successfully on several screw compressors.
Can we use mobile phone cameras for Motion Amplification?
Simply put, No. Jeff gave a detail reason during the webinar so if you missed the answer, check out the link for a full explanation from the inventor himself. In practice the package RDI supplies is a compact, portable system that is quick to setup and use. The camera itself is only the size of a gopro.
Could the technology be applied to linear movement?
Yes. The system can be used too track motion, measure the displacement and also take a vibration reading from the tracked point. See here for an example – https://youtu.be/eWf0f7_bPCg?t=359
