Bently Nevada 330130-040-10-00 4m Unarmored Cable

Product Overview

The 330130-040-10-00 is an authentic, high-precision 4.0-meter extension cable belonging to the Bently Nevada 3300 XL series. This unarmored, lightweight cable assembly has a net weight of exactly 0.204 kg and serves as a noise-immune electrical path connecting 8mm proximity probes to Proximitor Sensors. It is optimized for general-purpose, non-hazardous areas where liquid blocking is critical but explosive-gas certifications are not required.

Core Technical Advantages

• FluidLoc Oil Isolation: Features Bently Nevada's patented FluidLoc internal core structure, which seals the inner wire strands to prevent turbine oils, water, and process fluids from wicking through the cable into clean enclosure panels.
• Conduit-Ready Flexibility: Weighing a lightweight 0.204 kg, this unarmored option (10) eliminates the bulk of external steel cladding, allowing high flexibility for easy pulling through tight field conduits with multiple bends.
• Supplied Protection Tape: Each unit comes standard with premium silicone wrapping tape, allowing field engineers to tightly wrap the probe-to-cable joint as a convenient alternative to bulky mechanical connector protectors.

Technical Specifications

Installation & Maintenance Guide

• Electrical Length Matching: Ensure the total loop length matches your Proximitor Sensor's hardware calibration. This 4.0-meter extension lead must be combined with the correct probe configuration to satisfy the strict loop requirements of the 3300 XL Transducer system.
• Connector Connection Safety: While the included silicone tape offers convenience, Bently Nevada does not recommend relying on silicone tape for applications that continuously expose the probe-to-cable joint to pressurized turbine oil. Use a rigid connector protector boot instead.
• Unarmored Routing Precaution: Because this is an unarmored cable option (10), route the line inside protective conduit piping or metallic wire trays to prevent physical pinching and sharp structural wear.

Engineering Advantages

• Cost-Effective Maintenance: Specifying the 00 approval option cuts unnecessary certification overhead costs for safe plant zones while retaining Bently Nevada's signature 75Ω triaxial shield reliability.
• High Mechanical Reliability: Fully supports the 3300 XL standard design enhancements, maintaining stable signal feedback with less than 3% shift in scale factor under high relative humidity conditions.

Technical FAQs

Q1: What does the 10 option code stand for on this 330130 model?
A1: The 10 code means the cable features the FluidLoc liquid-blocking core barrier compound but is unarmored, making it highly flexible and lightweight (0.204 kg) for easier conduit installations.

Q2: Can I install this 00 approval cable in a hazardous area needing ATEX compliance?
A2: No. The 00 suffix means it is not certified for explosive environments. For locations requiring ATEX, IECEx, or CSA intrinsic safety ratings, select the 05 approval option.

Q3: Does the lack of armor affect the electrical accuracy of the proximity loop?
A3: Not at all. The armor layer is entirely mechanical. The inner core retains identical high-precision electrical specifications, maintaining standard resistance and capacitance thresholds for clear vibration tracking.
