I guessed that this is some form of vibration monitor as used by many maintenance engineers for diagnosing critical bearings on some (very) expensive machinery. It has been used for many years in preventative maintenance and is very cost affective when checking even slight anomolies in rotating machinery.
Of course, I could be wrong (again).
My question is will you still need the Guardian if you have already fitted the upgraded IMS assembly considering that no failures of the ceramic bearing have been reported by either Flat 6 or LN Engineering??
