AVM – AXIAL VIBRATION MONITOR

Unit that measures and displays peak-to-peak vibration from 0.00 mm to 10.00 mm by sending out current signal (4-20mA) proportional to distance between the crank shaft and inductive sensor to the monitoring unit using inductive sensor – Alarm/Monitoring Current Output – Slow Down Output – Setpoint Adjustment – Vibration High Alarm Output – Power Source & System Failure Alarm Output – Slow Down Delay Time – Crank Shaft Position Output – applied to MAN B&W and SULZER ENGINE of HYUNDAI, HSD ENGINE and STX ENGINE
