Bently Nevada 330130-070-00-00 3300 XL Standard Extension Cable

Description

330130-070-00-00 specifies a 7.0-meter (22.9 feet) unarmored 3300 XL standard extension cable. This model is configured with a standard coaxial cable body and standard miniature coaxial ClickLoc connectors (Option 00) on both ends, and it does not carry specific product-level hazardous area approvals (Option 00). Unlike armored or FluidLoc variants, this unarmored standard configuration is selected for installations where the cable is routed through protective conduits or in clean areas where mechanical abrasion and fluid ingress are not critical concerns.

This extension cable forms a continuous electronic path between a 3300 XL 8 mm proximity probe and a 3300 XL Proximitor sensor. The total system length (typically 9.0 meters or 5.0 meters) must match the Proximitor sensor configuration. With an operating temperature range up to +177 degC (+350 degF), the cable provides transmission of eddy-current proximity signals for shaft vibration, axial position, and rotor dynamic measurements in demanding rotating machinery environments.

Features

• Cable Length: 7.0 meters (22.9 feet) of standard coaxial transmission line.
• Standard Cable Jacket: Standard FEP insulation without stainless steel armor or FluidLoc barrier.
• ClickLoc Connectors: Gold-plated brass miniature coaxial connectors designed for a secure mechanical joint.
• No Connector Protector: Configured without a pre-installed fluorosilicone connector protector.
• Agency Approval Option: Not required (Option 00), optimized for standard, non-classified, or general-purpose locations.

Applications

• Vibration monitoring on steam turbines, gas turbines, and large industrial compressors.
• Rotor dynamic measurements and dynamic shaft displacement tracking.
• Thrust position and axial thermal expansion monitoring on utility turbogenerators.
• Rotating machinery protection loops in petrochemical plants, refineries, and power generation facilities.

Installation Guidelines

• Verify that the combined length of the proximity probe and this 7.0-meter extension cable matches the total length rating of the Proximitor sensor (e.g., a 2.0-meter probe plus 7.0-meter extension cable matches a 9.0-meter Proximitor sensor).
• Ensure ClickLoc connectors are kept free of dirt, oil, and moisture during installation. Clean with a dry cloth or approved electronics contact cleaner.
• Always make the coaxial connections finger-tight. Avoid using hand tools unless joining to non-XL stainless steel connectors which require a finger-tight connection plus an extra 1/8 turn.
• Secure the extension cable using proper conduit, cable trays, or structural clamps to avoid fatigue from high vibration. Avoid exceeding the minimum bend radius of 25.4 mm (1.0 inch).

Compliance and Certifications

• EMC Directive: Complies with European Union Directive 2014/30/EU (EN 61000-6-2 and EN 61000-6-4) when integrated within a complete monitoring system loop.
