Description

The Bently Nevada 330130-040-01-05 is a 4.0-meter (13.1 ft) standard extension cable designed for the 3300 XL 8mm Proximity Transducer System. This cable serves as the critical electrical link between the 3300 XL 8mm proximity probe and the 3300 XL Proximitor Sensor. It transmits the eddy current signal from the probe tip to the sensor, where it is processed into a voltage signal proportional to the distance between the probe and the monitored conductive surface.

This specific model features an armored cable construction for enhanced durability in industrial environments and includes the FluidLoc option, which prevents oil and other process fluids from migrating through the cable interior. It is fully compliant with hazardous area requirements including CSA, ATEX, and IECEx certifications.

Features

• 4.0-meter length with armored cable protection
• FluidLoc cable construction for superior fluid containment
• Hazardous area approval (CSA, ATEX, IECEx)
• Fully interchangeable with other 3300 XL system components
• Backward compatible with legacy 3300 series 5mm and 8mm transducer systems
• Designed for vibration and position monitoring in fluid-film bearing machines

Applications

• Turbomachinery protection (compressors, turbines, pumps)
• Vibration and position measurement on fluid-film bearings
• Keyphasor reference and rotational speed measurement
• High-temperature industrial machinery environments

Technical Specifications

Installation Guidelines

• Ensure the total length of the probe and extension cable matches the calibrated length for the specific Proximitor Sensor used (typically 5 meters or 9 meters).
• Handle with care to avoid kinking or crushing the coaxial cable, which can alter electrical impedance.
• Ensure all connections are tightened to the manufacturer's specified torque to maintain signal integrity and environmental sealing.
• Route cables away from high-voltage lines and sources of high electromagnetic interference (EMI).
• Verify that the hazardous area classification of the installation site matches the certification of the cable model.
• Always power down the Proximitor Sensor before disconnecting or connecting the extension cable.

FAQs

What is the difference between the -05 and -00 models?

The 330130-040-01-05 includes agency approvals for hazardous areas (CSA, ATEX, IECEx), whereas the -00 model is intended for non-hazardous, safe-area installations.

Can this cable be used with non-XL systems?

Yes, 3300 XL 8mm components are backward compatible with standard 3300 5mm and 8mm transducer systems, provided the total system length requirements are met.

What does the FluidLoc option provide?

The FluidLoc option is a specialized cable construction that prevents oil and other liquids from leaking out of the machine through the interior of the cable, which is essential for maintaining seal integrity in fluid-film bearing applications.
