Details
The Shaft Eccentricity Monitor is designed for high reliability for the plant’s most
critical rotating machinery. This 1-slot monitor is used together with other AMS 6500
monitors to build a complete API 670 machinery protection monitor. Applications
include steam, gas, compressors and hydro turbomachinery.
The main functionality of the Shaft Eccentricity Monitor is to accurately monitor shaft
eccentricity and reliably protect machinery by comparing vibration parameters against
alarm setpoints, driving alarms and relays.
Shaft eccentricity monitoring consists of a displacement sensor either mounted
through the bearing case or mounted internally on the bearing housing with an
eccentricity collar near the thrust bearing as the target. The displacement sensor
is a non-contact sensor measuring shaft movement proportional to shaft bowing
or bent shaft, below 600 rpm.
Shaft eccentricity monitoring is an important measurement on large sleeve bearing
machines for predictive and protection monitoring.
The AMS 6500 Machinery Health Monitor is an integral part of PlantWeb® and
AMS software.
PlantWeb provides operations integrated machinery health combined with the
Ovation® and DeltaV™ process control system. AMS software provides maintenance
personnel advanced predictive and performance diagnostic tools to confidently and
accurately determine machine malfunctions early.
