The 3500/50M Tachometer Module is a 2-channel module that
accepts input from proximity probes or magnetic pickups to
determine shaft rotative speed, rotor acceleration, orrotor
direction. The module compares these measurements against
user-programmable alarm setpoints and generates alarms
when the setpoints are violated.
The 3500/50M Tachometer Module is programmed using the
3500 Rack Configuration software. The following configuration
options are available:
l Speed Monitoring, Setpoint Alarming and Speed Band Alarming
l Speed Monitoring, Setpoint Alarming and Zero Speed Notification
l Speed Monitoring, Setpoint Alarming and Rotor Acceleration Alarming
l Speed Monitoring, Setpoint Alarming and Reverse Rotation
Notification
The 3500/50M Tachometer Module can be configured to supply
conditioned Keyphasor* signals to the backplane of the 3500
rack for use by other monitors. Therefore, you don’t need a
separate Keyphasor module in the rack.
