Product Overview
-
Brand: Bently Nevada
-
Series: 3500 Series Machinery Protection and Condition Monitoring System
-
Model: 3500/25M 126398-01
-
Function: Provides precise phase reference signals for machinery monitoring
Product Description
The 3500/25M 126398-01 is an enhanced Keyphasor module designed to deliver accurate phase reference signals for machinery protection and condition monitoring systems. It processes input signals from proximity probes, magnetic pickups, or optical encoders and converts them into digital pulse trains for phase analysis. This module is crucial for applications requiring precise synchronization of vibration data, enabling advanced diagnostics and predictive maintenance strategies.
Applications
-
Gas and Steam Turbines: Monitoring blade-pass frequencies and detecting combustion instabilities.
-
Centrifugal Compressors: Identifying aerodynamic instabilities like surge or rotating stall through phase shifts.
-
Pumps and Motors: Detecting misalignment, soft foot, and other mechanical faults.
-
Power Generation: Monitoring generator eccentricity and exciter alignment.
-
Marine Propulsion Systems: Tracking propeller shaft torsional vibrations.
Product Advantages
-
High Phase Accuracy: ±0.5° at 1× RPM, enabling precise vibration vector analysis.
-
Adaptive Signal Conditioning: Automatically compensates for sensor gap variations and electrical noise.
-
Dual-Sensor Voting Logic: Eliminates single-point failures, enhancing system reliability.
-
Programmable Notch Filter: Suppresses electrical interference from variable frequency drives (VFDs) or grid harmonics.
-
Seamless Integration: Direct synchronization with 3500/42M vibration modules for phase-coherent FFT analysis.
