The Bently Nevada 330130-085-01-05, also cataloged as the 330130 Standard Extension Cable, operates as a dedicated hardware component for physical signal transmission within 3300 XL proximity transducer system networks. The cable establishes a continuous electrical pathway between a 3300 XL proximity probe and a 3300 XL proximity sensor, ensuring low-attenuation delivery of high-frequency eddy-current RF signals without modifying phase or amplitude characteristics.

Technical Parameters

Eddy-Current Probe Scaling and Cross-Talk Suppression

To maintain accurate eddy-current probe scaling, this extension cable exhibits tightly controlled characteristic impedance to match the 3300 XL proximity sensor output stage. In adequate installations, it prevents impedance mismatch reflections that distort the -10 VDC target gap voltage validation window. The integrated coaxial shield provides deterministic cross-talk suppression under high-density multi-channel machinery monitoring layouts. This architecture preserves raw RF signal integrity across the 8.5 m physical length, preventing cross-channel modulation and phase shifts during dynamic rotor dynamics analysis up to high vibration frequencies.

Kit Packaging and Content

• One (1) Bently Nevada 330130-085-01-05 coaxial extension cable

• One (1) Pre-installed silicone interconnect protector sleeve (Option 01)

• Factory calibration certificate and physical parameter compliance sheet

• Heavy-duty desiccant packet for moisture mitigation during storage

Physical Dispatch Protocol

Delivery time: 3-5 days when payment finish, handled via expedited premium carriers DHL, FEDEX, or UPS. All units are vacuum sealed and enclosed inside specialized anti-static industrial packaging. Rigid multi-layer corrugated outer boxes protect the physical integrity of the miniature coaxial connectors against compression forces and mechanical shock during international transit.

Physical Routing and Shield Grounding Guidelines

• Maintain the minimum physical bend radius of 25.4 mm during layout execution to avoid local internal impedance deviations or mechanical strain on the fluoropolymer jacket.

• Run the extension cable inside dedicated, grounded low-carbon steel conduit frames when routing through areas with high electromagnetic fields to prevent induction noise.

• Verify that the physical connection points are completely dry before sliding the option 01 interconnect protector over the junction to block liquid intrusion.

• Do not allow the coaxial cable shell to come into contact with the machine casing or structural metal frames; insulation must be maintained to prevent ground loops.

• Tighten miniature coaxial connectors using the specified torque wrench tool to prevent loose threads or structural deformation of the internal contacts.

Engineering FAQ

Q: How does a change in the physical cable length impact the proximity system calibration?

A: Proximity systems are calibrated to a specific total electrical length, typically 5.0 m or 9.0 m. Replacing an 8.5 m extension cable with a different length changes system capacitance and inductance, which shifts the scale factor and invalidates the linear range.

Q: Can this cable be altered or spliced in the field if damaged?

A: No. Splicing or manually repairing the coaxial line alters the characteristic impedance, introduces signal reflection points, degrades cross-talk suppression, and introduces errors into the critical -10 VDC gap voltage monitoring feedback loop.

Q: What is the specific function of the option 01 interconnect protector?

A: The option 01 protector provides an environmental seal around the connection point between the probe lead and the extension cable, protecting the connection against moisture, oil, and cutting fluids found in industrial environments.

Q: Is this extension cable hot-swappable while the machinery monitoring system is powered?

A: While disconnecting the passive cable will not damage the proximity sensor electronics, it breaks the feedback loop, forcing the monitor channel into an invalid under-voltage state and triggering a system fault alert or trip action if not bypassed.
