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 machinery protection by continuously comparing monitored parameters against configured alarm setpoints to drive alarms, and essential machine information for operations and maintenance personnel .

Each channel accepts from 1 to 4 pressure transducer signals with input impedance of 10 kΩ for 3-wire transducers and 1.5-3.5 MΩ for 2-wire. Dynamic pressure sensitivity is 100 mV/psi. The monitor provides buffered transducer outputs on the front panel, each with coaxial connectors that are short-circuit protected. Recorder outputs provide +4 to +20 mA values proportional to monitor full-scale .

Front panel LEDs include OK, TX/RX, and Bypass indicators. High mode and low modes are available with programmable alarm time delays from 1 to 60 seconds. The monitor's update rate is approximately 100 ms or less.
