Bently Nevada 330104-00-20-05-02-00 Proximity Probe System

The Bently Nevada 330104-00-20-05-02-00, also cataloged as the 3300 XL 8 mm Proximity Probe System, operates as a dedicated hardware component for non-contacting vibration and displacement measurements within TSI (Turbomachinery Supervisory Instrumentation) systems.

Suffix Breakdown & Model Matrix

Hardware Specifications

Mechanical Monitoring & TSI Integration

The 3300 XL 8 mm transducer system employs advanced eddy-current probe scaling to provide a linear output proportional to the gap between the probe tip and the conductive target. During commissioning, gap voltage validation must be performed to ensure the transducer operates at the nominal -10 VDC center-point, guaranteeing accuracy within the rotor dynamics linear range. Integrated coaxial shielding provides inherent cross-talk suppression between adjacent channels, maintaining signal integrity in high-density mounting applications for Keyphasor and vibration monitoring.

Frequently Asked Questions

Q: Is this system compatible with non-XL 3300 series components?

A: Yes. The 3300 XL 8 mm system is fully backward compatible and interchangeable with non-XL 3300 series 5 mm and 8 mm transducer components, allowing for seamless integration into existing infrastructure.

Q: Does the system require manual bench calibration after component replacement?

A: No. The 3300 XL design supports complete component interchangeability, eliminating the requirement to match or bench calibrate individual probes, extension cables, or Proximitor sensors.

Field Installation Guidelines

• Mechanical Mounting: Secure the probe using the provided mounting hardware. Ensure the probe tip is clear of interference from surrounding metallic surfaces to prevent field distortion.
• Cable Routing: Use the ClickLoc coaxial connectors for all junctions. Maintain a minimum bend radius for the cable to avoid mechanical stress and impedance changes.
• Grounding: Ensure the rack chassis is properly connected to the plant instrument ground. The system common is tied to the chassis, and improper grounding may introduce 50/60 Hz interference.
• Gap Setting: Utilize a calibrated feeler gauge or the monitor's input voltage display to set the physical gap. Verify the reading matches the target machine's operating gap specifications.
