Product Description
The Bently Nevada 3500/44 Aeroderivative Monitor is an advanced four-channel vibration monitoring module designed specifically for aeroderivative gas turbine (GT) applications. It is part of the Bently Nevada 3500 Machinery Protection System, providing reliable continuous condition monitoring.
The monitor detects and diagnoses vibration behaviors in aeroderivative GTs by acquiring and processing sensor signals from accelerometers and Velomitors. It compares real-time measurements against configured alarm setpoints to ensure rapid detection of anomalies.
This module is capable of tracking 1X vibration, performing bandpass filtering, and integrating signals. The 3500/44 accepts input from two independent Keyphasor signals, allowing different tracking configurations per channel pair.
