330130-040-00-CN Bently Nevada 4m Proximity Sensor Cable

Product Overview

The Bently Nevada 330130-040-00-CN is a premium 3300 XL series extension cable engineered for critical machinery protection and industrial vibration monitoring systems. Spanning a precise length of 4.0 meters, this high-integrity cable is designed to bridge the gap between proximity probes and advanced ClickLoc proximity transducer sensors. Featuring upgraded structural materials, it provides superior shielding against harsh electromagnetic interference (EMI) and cross-talk, ensuring highly accurate signal transmission without distortion. This makes it an ideal fit for demanding rotation monitoring deployments in oil, gas, power generation, and heavy industrial processing facilities.

Core Technical Advantages

High-Coverage Shielded Insulation

Constructed with a robust 85% coverage braided shield wrapped around a 24 AWG tinned copper conductor, this cable effectively eliminates signal degradation and ambient noise floor spikes, maintaining reliable voltage waveforms even across complex cable trays.

Wide Operational Temperature Envelope

Insulated with high-performance fluoropolymer materials, the cable is fully rated to operate reliably within a broad temperature range from -40°C to 105°C. This allows it to resist thermal stress near high-temperature turbine casings and rotating machinery blocks.

Military-Grade Mechanical Resilience

Built to survive tight spatial routing and rough physical handling, the cable supports a tight minimum bend radius of 40 mm (8 times the outer cable diameter). Military-grade connector protectors safeguard the fragile terminal joints from mechanical shearing during installation.

Technical Specifications

Installation and Maintenance

Coaxial Alignment and Connector Mating

When attaching the 330130-040-00-CN to a proximity probe or transmitter, ensure the ClickLoc gold-plated pins are perfectly aligned before pressing them together. Avoid twisting the cable core during connection to prevent strain on the tinned copper wire strands.

Ingress Protection and Environmental Sealing

Although the fluoropolymer casing boasts an IP67 rating, all terminal connections located in high-moisture or oil-mist zones should be wrapped in silicone self-fusing tape or protected by oil-resistant flexible conduits to prevent fluid pooling around the contacts.

System Calibrations and Length Constraints

Proximity systems are precisely calibrated to specific total electrical lengths (typically 5-meter or 9-meter total system lengths). Always verify that adding this 4.0-meter extension matches your proximity sensor module's structural requirements for accurate gap measurement.

Engineering Advantages

Universal 3300 XL Compatibility

This extension cable interfaces seamlessly across Bently Nevada's standard 8mm and 11mm proximity systems. It reduces plant stock complexity by providing a standardized, multi-use replacement part for multiple sensor setups.

Stable Electrical Impedance

The 24 AWG tinned copper core layout delivers constant internal impedance profiles. This allows for clean transmission of high-frequency eddy current signals over the full 4-meter length without attenuation or artificial phases.

Corrosion-Resistant Tinned Strands

The conductor's tinned outer layer prevents copper oxidation caused by humid plant environments. This ensures low resistance at termination junctions over years of continuous equipment service.

Technical FAQs

Q1: What does the "-CN" suffix indicate on this specific Bently Nevada part number?

A1: The "-CN" suffix indicates that this cable configuration includes country-specific agency approvals and compliance documents required for importing and installing industrial hardware within the region.

Q2: Can I splice two 4-meter cables together to create an 8-meter extension link?

A2: No, slicing or joining extension cables is strongly discouraged. Altering the calibrated length changes the overall system impedance, which causes severe errors in sensor gap and vibration tracking.

Q3: Is a Certificate of Origin available for this 330130-040-00-CN cable?

A3: Yes, an official Certificate of Origin can be issued upon request during order processing. Please verify your specific compliance requirements with our technical sales team before shipment.
