The Bently Nevada 330104-00-12-05-02-00, also cataloged as the 330104 Proximity Probes, operates as a dedicated hardware component for non-contacting displacement and vibration measurements within 3300 XL Transducer System platforms.

Hardware Specifications

Eddy-Current Probe Scaling and Rotor Dynamics

The 3300 XL transducer system employs refined eddy-current probe scaling to translate shaft proximity into precise linear voltage outputs. Achieving optimal rotor dynamics monitoring requires accurate gap voltage validation, where the probe position is adjusted to a target of -10 VDC at the Proximitor output for a standard AISI 4140 steel target. This ensures the full utilization of the 2.0 mm linear range. Proper implementation is necessary to achieve effective cross-talk suppression in high-density bearing housing installations, preventing signal interference and ensuring high-fidelity data acquisition for radial vibration and axial position telemetry.

Frequently Asked Questions

Q: Can this probe be used as a drop-in replacement for standard 3/8-24 threaded probes?

A: No. The 330104 model features 1/4-28 UNF-2A threads. Physical mounting compatibility must be verified with the existing machine housing before installation.

Q: Is this probe compatible with standard 3300 XL Proximitor sensors?

A: Yes. It is designed for use within the 3300 XL Transducer System and maintains full electrical compatibility with the standard 3300 XL Proximitor series.

Q: What is the significance of the "unarmored" cable specification?

A: The unarmored cable offers higher flexibility and a smaller outer diameter compared to armored variants, facilitating easier installation in restricted cable routing channels.

Field Installation Guidelines

• Inspect the mounting port to verify the 1/4-28 UNF-2A thread specification.
• Thread the probe manually into the mounting bracket, ensuring no mechanical collision occurs between the probe tip and the shaft surface.
• Connect the ClickLoc miniature coaxial connector to the extension cable, confirming the locking collar is fully engaged to ensure electrical continuity.
• Monitor the DC output voltage at the Proximitor terminals while adjusting the probe gap.
• Secure the position of the probe once the gap voltage validation reaches the -10 VDC target.
• Apply appropriate torque to the locknut to prevent loosening due to machine vibration, adhering to standard engineering practices for 1/4-28 hardware.
• Route the cable along existing cable trays or conduits, keeping it separated from high-voltage lines to minimize potential electromagnetic interference.
