The Bently Nevada 330130-080-02-05, also cataloged as the 330130 Extension Cable, operates as a dedicated hardware component for RF signal transmission within 3300 XL Transducer System platforms. It provides the calibrated impedance connection path that links a proximity probe tip to a remote Proximitor sensor, facilitating physical voltage scaling without modifying loop capacitance parameters.

Eddy-Current Probe Scaling & Gap Voltage Validation

The calibrated electrical parameters of the 330130-080-02-05 extension cable are verified to achieve strict uniformity in eddy-current probe scaling matrices. The 75 ohm internal geometry controls impedance mismatching across the 8.0 meter line. This electrical consistency enables proper gap voltage validation targeting nominal -10 VDC baselines, preventing signal attenuation or high-frequency rolloff from distorting dynamic real-time rotor dynamics metrics.

Frequently Asked Questions

Q: What specific function does the -02 connector protector option perform in this assembly?

A: The connector protectors provide environmental isolation over the coaxial junctions, locking out moisture and contaminants while preventing bare metal grounding faults against nearby terminal boxes or layout structural channels.

Q: Can this 8.0 meter cable be utilized with any random length of proximity probe?

A: No. The total loop must match the fixed calibration constraints of the Proximitor sensor (typically 9.0 meters total system length when using an 8.0 meter cable combined with a 1.0 meter probe). Mismatching lengths shifts system capacitance and invalidates physical calibration.

Field Installation Guidelines

  • Verify that the extension cable length exactly corresponds to the configuration requirements of the matching 3300 XL proximity probe and Proximitor sensor module.
  • Observe standard bend radius parameters during installation to avoid collapsing the internal dielectric spacing of the 75 ohm coaxial core.
  • Ensure the integrated connector protectors are completely locked and seated across the connection junction to preserve circuit isolation before final cable laying.
  • Separate signal wiring runs from close proximity to alternating current power lines by utilizing dedicated grounded steel conduit channels to maintain cross-talk suppression.
