  • Radial Vibration Monitoring: Measures the dynamic displacement of a high-speed rotating shaft relative to the bearing housing, used to identify faults such as imbalance, misalignment, and fluid excitation (oil film oscillation).
  • Axial Displacement Monitoring: Monitors the thrust position of the rotor to prevent metal-to-metal friction between the rotor and stator; a critical protection parameter for turbines and compressors.
  • Phase Reference (Keyphasor®): Provides speed and phase reference signals for mechanical diagnostic analysis (such as Bode plots and polar coordinate plots).
  • Probe End: 3/8-24 UNF threaded mounting.
  • Cable Connection: Uses ClickLoc™ mini coaxial connectors (code -01) with an anti-loosening mechanism; a simple finger tightening ensures a low-impedance connection.
  • System Integration (Communication Layer):The preamplifier outputs a -200 mV/mil (7.87 V/mm) analog signal to the Bently Nevada 3500 monitoring system.
  • Linearity Range and Accuracy: Provides extremely high linearity within a 2.0 mm (80 mils) linear measurement range. System components (probe, cable, preamplifier) ​​are fully interchangeable, eliminating the need for recalibration when replacing parts.
  • Interference Immunity: Features excellent RFI/EMI shielding, maintaining an extremely low signal-to-noise ratio even in the complex electromagnetic environments of power plants, preventing false triggers.
  • High-pressure sealing: The probe tip is made of polyphenylene sulfide (PPS) and sealed to the stainless steel housing, enabling it to withstand high-pressure environments and preventing process media leakage.
