Bently Nevada 330103-00-06-10-02-05 3300 XL 8 mm Proximity Probe

Bently Nevada 330103-00-06-10-02-05 3300 XL 8 mm Proximity Probe

The Bently Nevada 330103-00-06-10-02-05, also cataloged as the 330103 Proximity Probe, operates as a dedicated hardware component for static (position) and dynamic (vibration) measurements within machine turbine supervisory instrumentation (TSI) platforms.

Hardware Specifications

Eddy-Current Probe Scaling & Calibration

The 330103-00-06-10-02-05 utilizes eddy-current probe scaling to convert physical distance into a proportional electrical signal via the Proximitor loop. Field verification requires rigid adherence to gap voltage validation targets. The nominal gap voltage calibration point is set at -10 VDC, corresponding to the center of the 2.0 mm linear displacement range. System integration eliminates the requirement for bench calibration due to full interchangeability between the 3300 XL 8 mm probes, extension cables, and Proximitor sensors. Cross-talk suppression must be maintained by isolating the probe cabling from adjacent high-voltage power lines to protect the integrity of the rotor dynamics data stream.

Frequently Asked Questions

Q: Is a bench calibration required when replacing only the 330103 probe?

A: No. The 3300 XL 8 mm components provide complete interchangeability, eliminating the requirement to match or bench calibrate individual components or loops.

Q: Is this 3300 XL probe backward compatible with legacy non-XL 3300 series systems?

A: Yes. Each component is backward compatible and interchangeable with non-XL 3300 series 5 mm and 8 mm transducer components, subject to total system length constraints.

Field Installation Guidelines

• Cable Protection: Ensure the extension cable connection is tight and insulated using self-fusing silicone tape or a dedicated connector protector to prevent fluid contamination and electrical grounding faults.
• Target Gap Validation: Adjust the probe mechanically within the housing until the digital multimeter indicates a gap voltage of -10 VDC (+/-0.5 VDC) at the Proximitor sensor test points, ensuring the probe tip is positioned in the center of its linear range.
• Routing Limitations: Maintain physical separation between transducer cables and high-power AC lines. Run probe wiring inside dedicated, grounded metal conduits to suppress electromagnetic interference (EMI) and signal crosstalk.
