The 3500/44M Aeroderivitive GT Vibration Monitor is a fourchannel instrument designed for aeroderivative gas turbine applications. It:
-Continuously monitors machinery by comparing monitored parameters against configured alarm setpoints to drive alarms.
-Communicates essential machine information for both operations and maintenance personnel.
The 3500/44M 176449-99 's Aero GT I/O modules interface to Velomitor sensors and accelerometers through Bently Nevada interface modules. The monitor uses the Prox/Velom I/O to interface to our .
Using the 3500 Rack Configuration Software, you can configure the 3500/44M 176449-99 Aeroderivitive GT Vibration Monitor for the following filter options:
-Signal Integration
-1X vibration tracking
-Band-pass vibration
The 3500/44M 176449-99 Aeroderivitive GT Vibration Monitor accepts input from two separate Keyphasor signals, allowing each channel pair to use a different tracking filter.
You can configure multimode channels to have up to eight sets of alarm parameters including alert and danger setpoints and alarm time delays. Each set may be configured for a specific machine mode.
As the machine changes modes, the monitor can switch to a specific set using contacts on multimode I/O modules or software commands through a communications gateway.
