Bently Nevada 330130-040-00-00 3300 XL Standard Extension Cable

The Bently Nevada 330130-040-00-00, also cataloged as the 330130 extension cable, serves as the primary coaxial link used to execute probe‑to‑proximitor signal transmission across 3300 XL eddy‑current measurement platforms. This configuration implements a 4.0 m system length, standard cable construction, and no agency‑approval requirements.

Hardware Specifications

Eddy‑Current Scaling and Signal‑Path Integrity

The 330130 extension cable preserves the calibrated eddy‑current probe scaling required for displacement interpretation within 3300 XL systems. Its coaxial geometry maintains the nominal −10 VDC gap‑voltage reference generated by the proximitor, ensuring linear response across the measurement range. Shielding continuity suppresses cross‑talk and minimizes induced noise, particularly in multi‑probe installations where rotor‑dynamic phase and amplitude accuracy depend on stable impedance. The factory‑matched 4.0 m length ensures proper compensation without requiring recalibration.

Frequently Asked Questions

Q: Can the extension cable be replaced while the proximitor remains energized? A: No. Replacement should occur only when the monitoring channel is de‑energized to avoid transient gap‑voltage excursions.

Q: Does altering cable length affect displacement scaling? A: Yes. System length is factory‑matched. Non‑standard cable lengths change impedance and can shift the scaling curve.

Q: Does the cable require firmware compatibility checks? A: No. The extension cable is a passive component and contains no firmware.

Field Installation Guidelines

Route the cable away from high‑current conductors to minimize electromagnetic interference. Maintain gentle bend radii to preserve coaxial impedance. Bond shielding at the proximitor end only to prevent ground‑loop formation. Verify connector seating to ensure stable signal transmission. Apply strain relief to prevent micro‑motion that may introduce noise into rotor‑dynamic measurements.
