The Bently Nevada 330130-040-02-CN serves as the primary 330130 Extension Cable utilized to execute high-frequency RF signal transmission across 3300 XL Series platforms. Configured as a passive, low-attenuation coaxial bridge within an eddy-current proximity transducer loop, this hardware connects the proximity probe to a Proximitor Sensor to transfer physical machine displacement data back to the processing monitor rack without phase distortion.

Option Code Parameter Breakdown

The distinct alphanumeric suffixes designate the predefined physical length, shielding armor, and regional certification properties of the cable assembly:

• 330130: Base model designator for the 3300 XL 8mm proximity extension cable system.

• 040: Cable Length option. Standardizes an absolute nominal length of 4.0 meters (13.1 feet).

• 02: Armor option. Standard coaxial cable configuration outfitted with a stainless steel braided armor sleeve.

• CN: Agency Approval option. Specifies local regulatory certifications and compliance for installation within specialized industrial regions.

Technical and Physical Specifications

Eddy-Current Loop Tuning and Cross-Talk Suppression

The capacitive and inductive electrical profiles of the 330130 cable series are matched to specialized eddy-current probe scaling matrices. Modifying the physical length of this line skews loop impedance parameters, which compromises the field gap voltage validation routines targeting a precise -10 VDC baseline at the monitor. The high-density external stainless steel braided armor layer provides integrated cross-talk suppression, shielding the micro-volt sensor loops from electromagnetic field interference caused by adjacent heavy machinery.

Field Deployment and Routing Instructions

Physical Layout Limits

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

• Secure the external stainless steel braided armor sleeve to structural supports at 300 mm intervals to isolate the line from machinery vibration.

• Maintain physical separation between sensor routing tracks and high-voltage AC electric power lines using dedicated metal conduits.

ClickLoc Connector Interface Engagement

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

• Align the male and female terminal joints and push together firmly until the internal mechanical detent locks.

• Slide the silicone connector protector completely over the mated junction to block external environmental oil ingress.

Transducer System Engineering FAQ

• Can this 4.0-meter extension cable be paired with a 1.0-meter proximity probe?

  Yes. This setup creates a 5.0-meter total system loop length, which must be connected to a matching 5.0-meter 3300 XL Proximitor module.

• What happens to the monitor reading if the internal FEP insulation layer is crushed?

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

• 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.

• What fault state is indicated during an open-circuit failure inside 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 re-terminate this cable to eliminate 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 loop behavior?

  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 ammonia or steam?

  Yes. The fluoropolymer formulation provides robust chemical resistance against corrosive gases, steam, and synthetic lubricants.

• Can this passive cable component be hot-swapped while the machinery monitor is powered?

  Yes. The passive sensor lead can be safely decoupled from the probe tail while the primary monitor chassis remains active.
