Overview: 3500/44M Aeroderivative GT Vibration Monitor

The 3500/44M Aeroderivative GT Vibration Monitor is a four-channel instrument tailored for aeroderivative gas turbine applications. Key features include:

• Continuous Monitoring: Continuously compares monitored parameters against configured alarm setpoints to trigger alarms.
• Operational Communication: Provides essential machine information for both operations and maintenance teams.
• Sensor Interface: Integrates with Velomitor sensors and accelerometers through Bently Nevada interface modules.
• I/O Compatibility: Uses Aero GT and Prox/Velom I/O modules for interfacing.
