Bently Nevada 330730-080-12-CN 3300 XL 11 mm Extension Cable

Description

Option 080 (8.0 m cable length) and Option 12 (FluidLoc cable with connector protector) specify this 3300 XL 11 mm extension cable configuration — 330730-080-12-CN, which functions as a specialized 3300 XL 11 mm Extension Cable. This triaxial cable connects a 3300 XL 11 mm proximity probe to a 330780 Proximitor sensor, enabling non-contact eddy-current displacement measurements for machine protection. When paired with a 1.0-meter probe, this 8.0-meter extension cable completes a calibrated 9.0-meter transducer system.

Unlike standard alternative configurations, this variant utilizes FluidLoc technology to prevent fluid migration along the interior of the cable and includes an integrated connector protector that seals the critical probe-to-cable joint against moisture, steam, and corrosive turbine oils. Additionally, this specific model features the -CN suffix, signifying compliance with China-specific hazardous area regulations and standards, making it suitable for regional petrochemical and power generation applications.

Features

• 8.0-Meter Length: Option 080 provides a 26.2-foot cable length for broad field-routing flexibility in large industrial machine trains.
• FluidLoc Cable Technology: Option 12 incorporates specialized sealing that prevents oil, water, or other process fluids from leaking or migrating inside the cable casing.
• Integrated Connector Protector: Pre-installed environmental protective sleeve shields the coaxial ClickLoc junction against physical wear and chemical contamination.
• China Certification Package: The -CN suffix guarantees certified compliance with NEPSI and CCC requirements for hazardous area deployments.
• High-Temperature Durability: Triaxial design with FEP (fluoroethylene propylene) insulation rated to perform across an extensive temperature range.
• Low Signal Loss: Optimized capacitance and resistance parameters maintain high-fidelity signal transmission up to 305 meters to the primary monitor.

Applications

• Steam and gas turbine shaft vibration monitoring
• Compressor and pump rotor axial position measurements
• Thrust bearing wear detection in utility and industrial power generation
• Refinery, chemical processing, and mining rotating machinery protection

Installation Guidelines

• Always match the combined probe length and extension cable length to the calibrated total system length of the Proximitor sensor (typically 9.0 meters total for an 8.0-meter extension cable and a 1.0-meter probe).
• Ensure the coaxial connectors are clean and dry before connection, and torque only to finger-tight or the recommended maximum of 0.565 N-m.
• Slide the integrated connector protector securely over the probe-to-cable joint to shield against industrial oils, solvents, and ambient moisture.
• Observe the 25.4 mm minimum bend radius during cable routing to prevent internal conductor fracturing or shielding degradation.

Compliance and Certifications

• NEPSI: China National Supervision and Testing Center for Explosion Protected Electrical Products (under -CN package)
• CCC: China Compulsory Certification (under -CN package)
• CE: European Community EMC Directive 2014/30/EU
• RoHS: European Community RoHS Directive 2011/65/EU and China RoHS
