EMERSON A6110 Shaft Relative Vibration Monitor
EMERSON A6110 Shaft Relative Vibration Monitor
DESCRIPTION
The Shaft Relative Vibration Monitor is designed for extremely 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 turbo machinery.
The main functionality of the Shaft Relative Vibration monitoring module is to accurately monitor shaft relative vibration and reliably protect machinery by comparing vibration parameters against alarm setpoints, driving alarms and relays.
Shaft relative vibration monitoring consists of a displacement sensor either mounted through the bearing case, or mounted internally on the bearing housing, with the rotating shaft being the target.
The displacement sensor is a non-contact sensor measuring shaft position and movement. Since the displacement sensor is mounted to the bearing, the monitored parameter is said to be shaft relative vibration, that is, shaft vibration relative to the bearing case.
