Bently Nevada 330130-075-10-CN 3300 XL Standard Extension Cable

Product Overview

330130-075-10-CN is a Bently Nevada 3300 XL standard extension cable designed for high-reliability vibration monitoring systems in refineries, gas turbines, steam turbines, compressors, and power generation assets. This extension cable connects 3300 XL proximity probes to Proximitor sensors and maintains signal integrity in continuous condition monitoring applications.

The 3300 XL series supports critical rotating equipment protection where stable vibration data directly reduces unplanned shutdown risk. Bently Nevada uses high-performance coaxial construction and industrial-grade shielding to improve resistance against electrical noise, oil contamination, and mechanical stress.

The 7.5 m cable configuration fits medium-distance field installations inside turbine enclosures, compressor skids, and hazardous process environments. The FluidLoc cable option improves sealing performance in oil-exposed applications and helps prevent fluid migration through the cable assembly. The -CN suffix identifies the China hazardous area approval package, including applicable NEPSI and related regional certifications for explosive gas environments.

Technical Specifications

Application Details

The 330130 extension cable operates within Bently Nevada proximity transducer systems used for shaft vibration and position monitoring. Engineers commonly install this cable in centrifugal compressors, steam turbines, hydro turbines, and critical motor systems.

FluidLoc technology improves reliability in oil-rich turbine compartments and lubrication-intensive machinery areas. The cable construction minimizes moisture ingress and maintains stable signal transmission during long-term operation under vibration and thermal cycling conditions.

Technical FAQs

Is the 330130-075-10-CN compatible with all 3300 XL probes?

This cable supports standard Bently Nevada 3300 XL 8 mm proximity transducer systems with compatible probe and Proximitor configurations.

What does the FluidLoc option provide?

The FluidLoc cable structure reduces fluid migration through the cable jacket. This feature improves reliability in turbine oil and compressor lubrication environments.

Can this cable operate in hazardous areas?

Yes. The -CN suffix includes China hazardous area approvals for applicable explosive gas installations when used within approved system configurations.

Does this extension cable require calibration after replacement?

Engineers should verify the complete transducer system length and perform gap voltage validation after installation. System calibration depends on the total matched probe system configuration.

Engineering & Installation Guide

Use dedicated cable routing away from high-voltage motor cables and VFD output wiring. Proper separation reduces electromagnetic interference during vibration signal transmission.

Do not exceed the specified bending radius during installation. Excessive cable stress may affect shielding performance and long-term signal stability.

Inspect connector sealing surfaces before installation in oil-contaminated environments. Clean mating surfaces improve environmental protection and connector reliability.
