BENTLY3500/44M - GT Vibration Monitor
Origin: United States
Brand: Bently Nevada
3500/44M is a Aeroderivitive GT Vibration Monitor designed and developed by Bently Nevada. The Aeroderivitive GT Vibration Monitor is a four-channel instrument intended for use with aeroderivative gas turbines. It constantly monitors machinery by comparing monitored parameters to configured alarm setpoints in order to generate alarms. It transmits critical machine data to both operations and maintenance personnel. Aero GT I/O modules communicate with Velomitor sensors and accelerometers via Bently Nevada interface modules. The monitor communicates with our via the Prox/Velom I/O. You can configure the Aeroderivitive GT Vibration Monitor for the following filter options using the Rack Configuration Software: 1X vibration tracking, Signal Integration, Vibration with a bandpass.
