330130-040-12-05 Bently Nevada 75 Ohm Triaxial Cable

Product Overview

The 330130-040-12-05 is a premium, high-performance 4.0-meter extension cable belonging to the Bently Nevada 3300 XL series. Weighing a nimble 0.136 kg, this unarmored configuration features a specialized flexible profile designed for smooth routing through dedicated protective conduits and tight machine enclosures. It serves as an essential component in critical machinery protection systems, accurately carrying raw high-frequency eddy current vibration signals from proximity probes directly to Proximitor Sensor units.

Core Technical Advantages

• FluidLoc Cable Technology: Utilizes a patented internal barrier compound that completely seals the cable interior, stopping process oils, moisture, and hazardous gases from leaking out of the machine housing through the cable core.
• High-Shielding Triaxial Geometry: Incorporates a premium 75Ω triaxial cable core wrapped in fluoroethylene propylene (FEP) insulation, delivering heavy-duty protection against radio frequency and electromagnetic interference.
• Optimized Unarmored Flexibility: At just 0.136 kg, this version avoids the bulk of heavy steel cladding, making it significantly easier to pull through tight multi-bend field conduits while providing the exact same high-precision electrical specifications.

Technical Specifications

Installation & Maintenance Guide

• Calibration Matching: Confirm that your total calibrated transducer loop length remains unified. This 4.0-meter extension cable must match the designated proximity probe length to fulfill the exact input configuration required by the 3300 XL Proximitor Sensor.
• Safe Routing Practices: Because this is an unarmored option (12), always route the cable inside an industrial metal conduit or wire tray to safeguard the FEP jacket against external cutting hazards or severe friction wear.
• Connector Protection: Always snap the pre-installed connector protector boots securely over the coaxial junction. This block shields gold-plated surfaces against turbine oil breakdown and prevents vibration loosening.

Engineering Advantages

• Extreme Thermal Performance: The premium FEP jacket allows the cable to perform with absolute precision across severe industrial environments, running reliably from -51 °C up to +177 °C.
• Global Intrinsic Safety: Outfitted with the 05 approval package, this cable fully satisfies international CSA, ATEX, and IECEx safety standards, certifying it for deployment in highly explosive atmospheres.

Technical FAQs

Q1: What is the main structural difference between option 12 and option 13 cables?
A1: Option 12 is an unarmored FluidLoc cable that prioritizes high flexibility and lightweight handling (0.136 kg), whereas option 13 includes an integrated outer layer of interlocking stainless steel armor for direct exposed routing.

Q2: Is the FluidLoc compound inside this cable safe against hot turbine oil?
A2: Yes. The internal sealing material and outer FEP insulation are engineered specifically to withstand continuous contact with corrosive process fluids and turbine lubricants without degrading.

Q3: Why is a 75Ω triaxial layout used instead of standard coaxial wire?
A3: The triaxial structure introduces an extra layer of active insulation and shielding. This design blocks electromagnetic noise from heavy industrial pumps and motors, keeping your proximity readings stable and free of signal jitter.
