Description:

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, or rotor direction. The module compares these measurements against user-programmable alarm setpoints and generates alarms when the setpoints are violated.

The Tachometer Module is programmed using the 3500 Rack Configuration software. The following configuration options are available:

Speed Monitoring, Setpoint Alarming and Speed Band Alarming

Speed Monitoring, Setpoint Alarming and Zero Speed Notification

Speed Monitoring, Setpoint Alarming and Rotor Acceleration Alarming

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.

The 3500/50M Tachometer Module has a peak hold feature that stores the highest speed, the highest reverse speed, or the number of reverse rotations that the machine has reached. You can reset the peak values.

Each 3500/50M Tachometer Module accepts up to two transducer signals from proximity probe transducers or magnetic pickups.

The 3500/50M Tachometer Module supports 1 to 255 events per revolution for Rotor Acceleration and Zero Speed channel types.

All other channel types support 0.0039 to 255 events per revolution.

All channel types support a maximum full scale range of 99,999 rpm and a maximum input frequency of 20 kHz.
