Application
-
Radial Vibration Monitoring: Detects bearing condition and identifies rotor imbalance and misalignment in rotating machinery.
-
Axial Thrust Position Measurement: Assesses thrust bearing wear to prevent potential bearing failure.
-
Rotor Stability Analysis: Determines attitude angle by measuring shaft average radial position.
-
Diagnostic Data Collection: Provides vibration amplitude and phase angle for Polar and Bode format plotting.
-
Eccentricity Measurement: Monitors rotor bow during startup and low-speed rotation.
System Compatibility & Alternative Models
- System Compatibility: Fully compatible with Bently Nevada 18745-series 7200 Proximitor Sensors (such as the 5-meter 18745-03 module), 21747 standard or armored extension cables, and legacy 3300 or 9000 Machinery Monitoring Systems.
- Alternative Model: 22810-00-03-05-02
- Key Differences: The 22811-00-03-05-02 is constructed as an unarmored standard configuration, leaving its FEP-insulated coaxial leading cable exposed for flexible routing inside protected conduits. Conversely, the 22810-00-03-05-02 is an armored model variant that integrates an outer stainless steel protective armor sleeve over the internal cable lead to defend against physical crushing, tearing, and aggressive mechanical abrasion on the factory floor.
