Application
-
Shaft Vibration Monitoring: Detects vibration levels on rotating machinery such as compressors, pumps, and turbines.
-
Thrust Bearing Assessment: Evaluates axial thrust position to identify bearing wear or potential failure.
-
Rotor Stability Analysis: Measures shaft average radial position to determine attitude angle for stability assessment.
-
Diagnostic Plotting: Captures vibration amplitude and phase angle data for Polar and Bode format analysis.
-
Startup Eccentricity Measurement: Monitors rotor bow during startup to prevent unnecessary machine trips.
