The Bently Nevada 330130-080-03-00, also cataloged as the 330130 Extension Cable, operates as a dedicated hardware component for high-frequency RF signal transmission within 3300 XL 8mm Proximity Transducer platforms. Configured for proximity loop connections in machinery protection systems, the hardware establishes low-attenuation electrical continuity between the inductive probe tip and the external Proximitor Sensor unit. The coaxial parameters are structured to transmit raw impedance modifications to the processing monitor without phase lag.

Configuration Options Matrix

The discrete alphanumeric suffix options define the absolute length, structural armoring, and safety classification status of the cable hardware:

Core Hardware Parameters

Eddy-Current Loop Tuning and Signal Preservation

The electrical characteristics of the 330130 cable assembly are matched to precise eddy-current probe scaling matrices. Modifications to the physical length or localized dielectric properties distort loop impedance, generating errors during gap voltage validation steps targeting -10 VDC at the monitor rack. High-density internal shielding ensures robust cross-talk suppression between adjacent transducer paths, isolating subtle high-frequency rotor dynamics from surrounding industrial electromagnetic noise.

Transducer Cable Routing Directives

Coaxial Connection Sequence

• Inspect internal mating surfaces of ClickLoc connectors to confirm they are dry and free of particulate debris.

• Engage the male and female connector halves firmly until the internal mechanical detent locks into place.

• Slide the silicone connector protector completely over the connection interface to isolate it from fluids.

Field Layout Constraints

• Maintain a strict minimum physical bend radius of 25.4 mm (1.0 inch) along all segments of the run.

• Separate the sensor line from high-voltage AC electrical lines using dedicated grounded conduit.

• Fix the armored jacket to structural supports at 300 mm intervals to isolate the line from machinery vibration.

Transducer Interconnect FAQ

• Can this 8.0-meter extension cable be combined with a 1.0-meter proximity probe?

  Yes. A 1.0-meter probe combined with an 8.0-meter cable establishes a 9.0-meter system length, matching a calibrated 9.0-meter 3300 XL Proximitor module.

• What occurs if the FEP cable core is crushed or flattened under the armor?

  Crushing modifies the internal core-to-shield capacitance, shifting the eddy-current probe scaling parameters and inducing measurement errors.

• Does the stainless steel braided armor support direct exposure to mechanical scrape hazards?

  Yes. The armor layer provides physical defense against abrasion, but the cable must still avoid tight pinches or crushing impacts.

• What specific reading points to an open-circuit failure within the coaxial core?

  The companion 3500 series monitor rack reports a "Not OK" status fault and clamps the transducer output to its maximum negative rail limit.

• Can field technicians cut and resplice this cable to reduce physical slack?

  No. Cutting shifts the absolute line impedance, which invalidates the pre-calibrated scale factor of 7.87 V/mm.

• How does oil contamination inside the ClickLoc connection affect performance?

  Oil shifts the baseline gap voltage validation target away from the nominal -10 VDC point, causing false drift or vibration alarms.

• Is the FEP insulation jacket resilient against continuous exposure to industrial turbine oils?

  Yes. The fluoropolymer formulation provides robust chemical resistance against degradation from exposure to synthetic or mineral-based lubricants.

• Where should the electrical shield layer of this extension cable be grounded?

  The shield must remain isolated from the machine frame and terminate to earth ground solely at the Proximitor Sensor terminal chassis block.
