Bently Nevada 3500/50M Tachometer Module

Description

The 3500/50M Tachometer Module is a 2-channel modulethat accepts input from proximity probes or magneticpickups to determine shaft rotative speed, rotor acceleration,or rotor direction. The module compares thesemeasurements against user-programmable alarm setpointsand generates alarms when the setpoints are violated.The Tachometer Module is programmed using the 3500 RackConfiguration software. The following configuration optionsare available:l Speed Monitoring, Setpoint Alarming and Speed BandAlarmingl Speed Monitoring, Setpoint Alarming and Zero SpeedNotificationl Speed Monitoring, Setpoint Alarming and RotorAcceleration Alarmingl Speed Monitoring, Setpoint Alarming and ReverseRotation NotificationThe 3500/50M Tachometer Module can be configured tosupply conditioned Keyphasor signals to the backplane ofthe 3500 rack for use by other monitors. Therefore, you don’tneed a separate Keyphasor module in the rack.The 3500/50M Tachometer Module has a peak hold featurethat stores the highest speed, the highest reverse speed, orthe number of reverse rotations that the machine hasreached. You can reset the peak values.
