Bently Nevada 330881-28-00-050-03-02 PROXPAC XL Proximity Transducer

The Bently Nevada 330881-28-00-050-03-02, also cataloged as the 330881 PROXPAC XL transducer, operates as an integrated probe‑plus‑Proximitor assembly for displacement measurement within 3300 XL rotor‑dynamic monitoring networks. It provides a 50 mm penetration probe, NPT mounting, and full hazardous‑area certified sensing behavior.

Eddy‑Current Probe Scaling & Gap‑Voltage Validation

The PROXPAC XL assembly maintains calibrated eddy‑current scaling across its integrated probe and Proximitor electronics. Gap‑voltage validation follows the standard −10 VDC target, ensuring linear displacement behavior across the 2.0 mm measuring span. The 50 Ω output impedance stabilizes signal transmission over field cable lengths up to 305 m, suppressing phase distortion during rotor‑dynamic analysis. Cross‑talk suppression is achieved through internal shielding and matched impedance paths, allowing multi‑probe installations around large shafts without channel interference.

Frequently Asked Questions

Q: Can the transducer be removed while the Proximitor remains energized? A: Removal should occur only when the channel is de‑energized to avoid transient gap‑voltage excursions.

Q: Does the 50 mm penetration depth require recalibration? A: No. Penetration depth is mechanically defined; electrical calibration is governed by the probe/Proximitor pairing.

Q: How does long‑distance cabling affect frequency response? A: The assembly supports up to 305 m of field cable; attenuation remains within the specified 0 Hz to 10 kHz band.

Field Installation Guidelines

  • Maintain a clean mounting surface to ensure stable eddy‑current field alignment.
  • Verify 3/4‑14 NPT thread engagement to avoid mechanical drift under vibration.
  • Ground shielding at the Proximitor end only to prevent ground‑loop formation.
  • Avoid sharp cable bends to preserve coaxial impedance.
  • Confirm recommended 1.27 mm gap before energizing the monitoring channel.
