The Bently Nevada 3500/64M Dynamic Monitor is a single slot, four channel monitor that accepts input from high temperature pressure transducers and uses this input to drive alarms. The monitor's one measured variable per channel is band pass dynamic pressure.

The 3500 Rack Configuration Software configures the band pass corner frequencies along with an additional notch filter. The monitor provides a recorder output for control system applications. The primary purpose of the 3500/64M Dynamic Pressure Monitor is to provide the following:

  • Machinery protection by continuously comparing monitored parameters against configured alarm setpoints to drive alarms
  • Essential machine information for operations and maintenance personnel
