Bently Nevada 330730-040-02-00 3300 XL 11 mm Extension Cable

Description

Option 040 (4.0 m cable length) and Option 02 (standard cable with connector protector) specify this 3300 XL 11 mm extension cable configuration — 330730-040-02-00. This unarmored coaxial cable links a 3300 XL 11 mm proximity probe with a 3300 XL 11 mm Proximitor sensor, completing a 5.0-meter or 9.0-meter transducer system. The standard FEP insulation offers excellent chemical resistance and temperature tolerance in demanding industrial environments.

Unlike armored variants or those featuring FluidLoc technology, this configuration focuses on flexibility and clean routing while adding a pre-installed fluorosilicone connector protector. The connector protector shields the ClickLoc junction against moisture and contaminants, which is ideal for humid or wet environments. Since Option 00 is selected for agency approvals, this specific variant does not require hazardous area compliance certificates.

Features

• Option 040 provides a 4.0-meter (13.1 feet) physical cable length.
• Option 02 equips the cable with a pre-installed fluorosilicone connector protector on the female end.
• Option 00 designates that no specific hazardous area agency approvals are required for this configuration.
• 75 Ohm triaxial construction with fluoroethylene propylene (FEP) insulation.
• Gold-plated brass ClickLoc coaxial connectors lock securely to prevent loosening from vibration.
• Unarmored cable design maintains a minimum bend radius of 25.4 mm (1.0 in) for tight routing paths.
• Rated tensile strength of 270 N (60 pounds) at the probe lead to extension cable connection.

Applications

This extension cable is used within Bently Nevada 3300 XL 11 mm proximity transducer systems for vibration and position monitoring of large rotating machinery. Typical applications include:

• Steam and gas turbine shaft vibration and axial thrust position monitoring.
• Centrifugal and axial compressor vibration analysis.
• Critical rotating machinery protection where 11 mm probe systems are required.
• Humid or moist industrial environments where the connector protector prevents ingress of moisture into the coaxial junction.

Installation Guidelines

When installing the 3300 XL 11 mm extension cable, follow these engineering best practices to ensure optimal signal transmission and mechanical longevity:

• Bend Radius: Maintain a minimum bend radius of 25.4 mm (1.0 in) along the entire cable length to prevent internal conductor damage or impedance changes.
• Connection Integrity: Hand-tighten ClickLoc coaxial connectors. Do not use pliers or other tools that could over-torque and damage the gold-plated contacts.
• Connector Protection: Ensure the pre-installed fluorosilicone connector protector is fully seated and clicked over the junction to block moisture, dirt, and industrial oils.
• Routing and Conduit: Route the cable through dedicated, grounded metal conduit to isolate the low-voltage signal from high-voltage electromagnetic interference (EMI) sources.
• Grounding: Ensure the system shield is properly grounded at the monitor/instrumentation end only. Do not ground the cable shield at multiple points, as this can introduce ground loops.

Compliance and Certifications

The 330730-040-02-00 configuration is ordered with the Option 00 agency approval selection. As such, this specific extension cable is designed for use in non-hazardous, general-purpose industrial environments and does not carry individual explosion-proof or intrinsic safety certificates.

• RoHS: Compliant with European Community Directive 2011/65/EU (RoHS).
• Electromagnetic Compatibility (EMC): Complies with European Community Directive 2014/30/EU when used as part of a fully compatible and shielded Bently Nevada 3300 XL transducer system.
