Misalignment Detection: Cross Channel Phase and Fault Frequencies

In this demonstration the CSI 2140 uses the analysis expert called "Cross Channel Phase" to verify a misalignment condition

Former EPM field analyst. Miss the 2140. Nothing compares for the speed, intuitive, the speed, all contained, the speed, the durability ... and it's pretty fast too. Breaks my heart they had to "restructure", but it's still a great company and great products.

great and easy to understand explanation of the use of phase shift

Very useful information

Drew thanks for that excellent presentation. I have a few questions. I'm noticing on the spectrum used to diagnose the misalignment was labeled F1P. From my knowledge using the CSI system, is this a PeakVue reading as the spectrum was in G's.
Also using the Cross Channel Phase with the new CSI 2130, can just the 2 sensors be used across the coupling to confirm the misalignment? Thanks

When use 2 sensor at cross channel phase methode, why degrees only 0?

[@Scoot54rq]

Just to add to Rishi's question, why wouldn't we be looking at B & C for cross channel phase? I'm not understanding the phase shift of 64 degrees between A & B also.

Thanks for the explanations. I carried out cross channel Phase with 2140 and the coherence is not 1 (actually less than 1), how does that affect the phase reading ?

[@josephajimuda938]

Coherence value is not necessarily 1. It can be 0.95. It is only testing the linearity of the system.

@@josephajimuda938 yes, i know better now. Thanks.
