Overview Manuals Principle

Features:

  • Bently Nevada 3500/50 Tachometer Module
  • The Tachometer Module is programmed using the 3500 Rack Configuration software.
  • Each 3500/50M Tachometer Module accepts up to two transducer signals from proximity probe transducers or magnetic pickups.
The Bently Nevada 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 3500/50 Bently Nevada Tachometer Module may still be available for purchase and support from Moore Automated Company beyond End-Of-Life (EOL) by the manufacturer (OEM).
Bently Nevada 3500/50 133388-01 Tachometer Module Manuals(Datasheets), Link Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
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.
