I have cracks and breaks in a Screening and I want to measure phase, if someone has the procedure of how to measure the phases, we have been applying solder and it is breaking again

Thanks.

Before welding (not soldering) structure, I suggest inspecting for loose or broken springs, fasteners, and drive elements. After repair, check tuning by verifying correct speed and amplitude for the material on the screen. The OEM (MEKA) should have a procedure to get the machine to operate without structural failure. I think the failures are due to operation and maintenance issues that need review and correction.

What vibration instrument do you have, and what phase do you want to measure?

I am attaching a paper on cross-channel phase analysis of vibrating screens from CSI.  The analysis of cross channel phase readings will be the same regardless of analyzer manufacturer and for all practical purposes, you can consider CSI's PeakVue and SKF's Demod to be the same.

I hope it helps.

There's more on the SKF website but you may have to pay $5.
