Bently Nevada 330709-000-060-50-02-05 11 mm Proximity Probe

Bently Nevada 330709-000-060-50-02-05 11 mm Proximity Probe

The Bently Nevada 330709-000-060-50-02-05, also cataloged as the 3300 XL 11 mm Proximity Probe, operates as a dedicated hardware component for non-contacting vibration and displacement measurements within TSI (Turbomachinery Supervisory Instrumentation) systems.

Hardware Specifications

Mechanical Monitoring & TSI Integration

The 3300 XL 11 mm transducer system requires precise eddy-current probe scaling to maintain linearity across its extended range. During commissioning, gap voltage validation must be performed against the nominal -10 VDC target to ensure the probe is positioned within the linear operating region of the target rotor surface. Proper cross-talk suppression is achieved through the use of high-frequency shielding in the miniature coaxial cabling, preventing signal interference when multiple probes are mounted in close proximity on rotor dynamics monitoring installations.

Frequently Asked Questions

Q: Can the 3300 XL 11 mm probe be used with 7200-series Proximitor Sensors?A: No. The system components are not interchangeable. All components, including the probe, extension cable, and Proximitor Sensor, must be replaced with 3300 XL series hardware.

Q: What is the primary requirement when integrating this probe with a 3500 Monitoring System?A: Firmware and Software Compatibility. The 3500 Monitoring System must utilize a version of the configuration software that explicitly lists the 3300 XL 11 mm Transducer System as a selectable and compatible hardware option.

Field Installation Guidelines

• Mechanical Mounting: Ensure the probe is mounted in a rigid bracket to prevent mechanical resonance. The probe tip must be clear of surrounding structures to avoid erroneous signal attenuation.
• Cable Routing: Maintain a minimum bend radius for the miniature coaxial cable to prevent internal conductor damage. Keep cables away from high-voltage AC lines to prevent EMI injection.
• Grounding: The system relies on the monitor chassis ground. Ensure the probe and extension cable shield are maintained according to standard loop integrity practices.
• Gap Adjustment: Utilize a calibrated feeler gauge or the associated monitor gap voltage reading to set the mechanical gap during installation, ensuring the target remains within the linear range of the probe's electromagnetic field.
