Bently Nevada 330130-040-10-05 3300 XL 4m FluidLoc Extension Cable

Product Overview

The 330130-040-10-05 is a premium, high-precision 4.0-meter extension cable manufactured in the U.S.A. by Bently Nevada for their industry-standard 3300 XL 8 mm proximity transducer series. Having a lightweight unarmored layout with a total net hardware weight of 0.204 kg, this extension line acts as a noise-exempt link that passes high-frequency eddy current data between proximity probes and Proximitor Sensors. This ensures clean asset condition monitoring for critical high-speed rotating turbomachinery.

Core Technical Advantages

• Patented FluidLoc Barrier: Outfitted with Bently Nevada's specialized FluidLoc architecture, which structurally blocks internal capillary paths to halt turbine oil, chemical vapors, and moisture from leaking out of the machine housing through the inner channels of the cable.
• Unarmored Routing Efficiency: Weighing exactly 0.204 kg (calculated at 34 g/m), this unarmored configuration offers excellent bending flexibility, making it perfect for rapid installation and pulling through multi-bend field conduits.
• Industrial Leak Protection: Includes complimentary silicone wrapping tape to insulate individual probe-to-cable connections, safeguarding gold-plated terminal contacts against dust and general plant humidity.

Technical Specifications

Installation & Maintenance Guide

• Fluid Exposure Warning: Although each package includes standalone silicone tape, do not rely on silicone tape alone if the probe-to-extension cable link is directly exposed to harsh turbine oil. For high-splash fluid zones, deploy a mechanical connector protector sleeve.
• Loop Length Matching: To prevent measuring drift, this 4.0-meter extension lead must be paired exclusively with matching 3300 XL 8 mm probes and Proximitor sensors calibrated for standard AISI 4140 steel targets.
• Field Wiring Practices: Connect the proximity sensor using a high-grade 3-conductor shielded triad field cable (16 to 24 AWG). Keep the maximum loop routing distance below 305 meters (1,000 feet) to prevent high-frequency signal roll-off.

Engineering Advantages

• Intrinsically Safe Operation: Featuring the 05 approval option, this cable satisfies rigorous CSA, ATEX, and IECEx hazardous area safety codes, allowing worry-free configuration in environments containing explosive vapors.
• Robust Electrical Consistency: Tight manufacturing tolerances ensure an ultra-stable inner conductor core resistance ($0.88 \pm 0.13\,\Omega$), maintaining a low scale factor error (less than 3% change in scale factor over 56 days under 93% relative humidity).

Technical FAQs

Q1: What does the 10 option code mean for this Bently Nevada cable?
A1: The 10 option stands for an unarmored FluidLoc cable style. It skips the metal conduit layer to offer maximum bend flexibility and a lighter weight profile (0.204 kg), while keeping full internal liquid-blocking capabilities intact.

Q2: Can this cable be used with non-XL or older Bently Nevada hardware?
A2: While 3300 XL components feature advanced structural upgrades like CableLoc (330 N pull strength), they are compatible with older 3300-series hardware. However, peak accuracy limits apply when running a full 3300 XL 8mm component loop.

Q3: Does the unarmored design mean it cannot stop oil migration?
A3: No. The internal FluidLoc design is fully active inside this unarmored cable, meaning it stops oil from wicking down the inner wire strands even without an outer layer of stainless steel armor.
