The Bently Nevada 3500/44M Aeroderivative GT Vibration Monitor is a four channel instrument designed for aeroderivative gas turbine applications. The Aero GT I/O modules interface to velocity transducers through Bently Nevada interface modules, part numbers 86517 and 86497. The monitor uses the Prox/Velom I/O to interface to Velomitor sensors and accelerometers.

The 3500 Rack Configuration Software configures the 3500/44M for the following filter options: Signal Integration, 1X vibration tracking, and Band-pass vibration. The monitor accepts input from two separate Key phasor signals, allowing each channel pair to use a different tracking filter.

Alarms are adjustable from 0 to 100% of full-scale with programmable alarm time delays. The monitor is specifically designed for the unique monitoring requirements of aeroderivative gas turbines in power generation and mechanical drive applications.
