Configured for high-frequency RF signal transmission in machinery asset optimization networks, the Bently Nevada 330130-040-03-00 (330130 Extension Cable) provides direct physical/electrical execution. This low-capacitance coaxial link bridges the connection between a 3300 XL 8mm proximity probe and a Proximitor Sensor, acting as a tuned passive component within the eddy-current displacement circuit to relay raw physical impedance metrics without phase deviation.

Part Number Nomenclature

The alphanumeric suffixes define the mechanical dimensions, structural defense options, and regulatory certifications of this cable layout:

• 330130: Base model identification for the 3300 XL 8mm standard extension cable.

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

• 03: Armor and Cable option. Incorporates FluidLoc coaxial core layout protected inside a stainless steel braided armor sleeve.

• 00: Agency Approval option. Non-certified configuration for applications requiring no specialized hazardous area approvals.

Physical and Electrical Parameters

Eddy-Current Probe Scaling and Signal Interference Prevention

The electrical capacitance and inductance parameters of the 330130 coaxial system are precisely configured to match industry-standard eddy-current probe scaling rules. Alterations to the physical cable length shift loop impedance, disrupting the gap voltage validation routines that target -10 VDC at the monitor rack center. To preserve signal integrity across high-speed rotor dynamics monitoring, the braided shield architecture maintains continuous cross-talk suppression, preventing inductive noise from adjacent high-voltage machinery lines.

Field Layout and Installation Protocols

Physical Routing Limitations

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

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

• Route the transducer cable in dedicated, isolated metal conduits apart from high-voltage AC electrical lines.

ClickLoc Interface Engagement

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

• Push the male and female connector halves together along a linear axis until the internal mechanical detent locks.

• Slide the silicone connector protector completely over the mated connection to prevent environmental oil ingress.

Transducer Loop Engineering FAQ

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

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

• What happens to the monitor reading if the FEP coaxial core is crushed?

  Crushing modifies the internal core-to-shield spacing, altering the pre-calibrated scale factor and introducing measurement errors.

• Where must 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 error state indicates a complete open-circuit failure inside the cable?

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

• Can a field technician cut and splice this cable to fit a shorter run?

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

• How does oil contamination inside the ClickLoc terminal 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 exposure to industrial lubricants?

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

• Can this passive extension cable link be hot-swapped while the monitor is live?

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