Bently Nevada 330730-080-00-05 3300 XL 11 mm Extension Cable

Description

330730-080-00-05 specifies this 3300 XL 11 mm extension cable configuration, featuring an 8.0-meter cable length, standard unarmored coaxial construction, and multiple hazardous area agency approvals. This cable serves as a link within the non-contact eddy-current transducer system, connecting the proximity probe to the Proximitor sensor.

Unlike variants that incorporate stainless steel armor or connector protectors, this standard triaxial cable configuration maintains a compact outer diameter of 3.7 mm, maximizing flexibility during installation inside conduits. It operates under challenging conditions, withstanding temperatures from -52 degC to +177 degC while preserving low electrical loss and consistent capacitive properties required for vibration and position monitoring.

Features

• Cable Length: 8.0 meters (26.2 feet) of triaxial cable matching standard system requirements.
• Cable Type: Standard unarmored triaxial cable featuring chemical-resistant fluoroethylene propylene (FEP) insulation.
• Connector Design: Miniature coaxial ClickLoc connectors at each end for standard, tool-free coupling.
• Agency Approvals: Multiple hazardous area certifications under Option 05, including CSA, ATEX, and IECEx.
• Routing Flexibility: 25.4 mm minimum bend radius allows installation within restricted machinery spaces.

Applications

This extension cable is used in 3300 XL 11 mm proximity transducer systems on rotating machinery, including:

• Steam and gas turbine shaft vibration and axial position monitoring.
• Centrifugal and reciprocating compressor rotor position sensing.
• Rotating machinery protection in oil, gas, chemical, and power generation facilities.

Installation Guidelines

• Bend Radius Control: Route the cable to ensure no bend is tighter than the 25.4 mm (1.0 inch) minimum limit, protecting the internal coaxial structure.
• Connection Security: Connect ClickLoc coaxial joints hand-tight. Do not apply tools that could exceed the maximum torque limit of 0.565 N-m (5 in-lb).
• Moisture Mitigation: Ensure connections are protected from oil and moisture. Avoid silicone tape in environments where probe-to-extension cable joints are exposed to turbine oil.
• System Matching: This 8.0-meter cable must be matched with a 1.0-meter probe to align with a 9.0-meter Proximitor Sensor calibration.
