The Bently Nevada 330130-080-02-00, also cataloged as the 330130 Extension Cable, operates as a dedicated hardware component for RF signal transmission within 3300 XL Proximitor Sensor networks. It serves as the calibrated passive connection linking an eddy-current proximity probe to a remote processing transducer, executing high-frequency analog parameter tracking without introducing loop capacitance mismatches.

Eddy-Current Probe Scaling & Gap Voltage Validation

The physical geometry and specialized shielding of the 330130-080-02-00 extension cable maintain precise electrical impedance parameters across its 8.0 m path. This continuous matching is required to preserve factory eddy-current probe scaling configurations. By enforcing uniform capacitance levels, the cable prevents high-frequency signal rolloff and attenuation, allowing accurate gap voltage validation targeting nominal -10 VDC baselines across complex machinery rotor dynamics monitoring zones.

Frequently Asked Questions

Q: What is the mechanical function of the integrated connector protectors specified by the -02 suffix?

A: The connector protectors provide an environmental seal over the miniature coaxial connections, preventing liquid or particulate ingress and eliminating accidental grounding faults caused by bare metal contact with local enclosures.

Q: Can this 8.0 m cable be swapped into a loop designated for a 5.0 m total system length?

A: No. Proximitor sensors are factory-tuned for specific cumulative electrical lengths (such as 5.0 m or 9.0 m loops). Installing an incorrect cable length disrupts the loop capacitance, invalidating the calibrated linear scale factor.

Field Installation Guidelines

  • Verify that the 8.0 m extension cable is paired with a 1.0 m proximity probe to ensure the total physical loop meets the 9.0 m specification of the destination Proximitor sensor.
  • Do not apply tight physical routings that drop below the minimum static bend radius limit of 25.4 mm to avoid permanent core dielectric deformation.
  • Ensure the integrated connector protectors are completely seated and locked over the coaxial joint to maintain physical and environmental isolation.
  • Separate non-armored transducer cabling from high-voltage distribution lines by placing them within dedicated grounded metal conduits.
