Bently Nevada 330130-045-03-05 3300 XL Armored Extension Cable

Description

Option 045 (4.5 meters length) and Option 03 (armored cable with connector protector) specify this 3300 XL standard extension cable configuration — 330130-045-03-05. This 3300 XL armored extension cable transmits high-frequency eddy-current signals from a 3300 XL 8 mm proximity probe to a compatible 3300 XL Proximitor sensor. It acts as an electrical link, maintaining calibration impedance in heavy industrial machine environments.

The integrated flexible stainless steel armor (Option 03) shields the cable core from mechanical crush risks, severe abrasion, and sharp casing edges. This specific configuration also features a pre-installed fluorosilicone connector protector to isolate the coaxial union from lubricating oils, water, and ambient dust. With Option 05 approvals, this cable meets international safety certifications for hazardous environments, distinguishing it from uncertified standard configurations.

Features

• Stainless Steel Armor: Flexible metallic armor wraps the coaxial lead to resist physical crush hazards and sharp bends.
• Pre-installed Connector Protector: Elastomeric sleeve isolates and seals the coaxial connection against fluid ingress and particulate contamination.
• 4.5 Meters Cable Length: Option 045 specifies the physical length required for matching system electrical length constraints.
• ClickLoc Coaxial Connectors: Gold-plated brass connectors lock together mechanically, preventing self-loosening under structural machinery vibration.
• Hazardous Location Certification: Certified for ATEX, IECEx, and CSA hazardous areas under the Option 05 classification.

Applications

• Steam turbine shaft radial vibration and axial thrust position tracking
• Industrial gas turbine bearing housings and casing vibration paths
• High-pressure compressor shaft movement and relative expansion monitoring
• Thrust bearing oil-film wedge thickness measurements in petrochemical pumps

Installation Guidelines

Verify that the combined length of the proximity probe and the extension cable matches the total system calibration rating of the Proximitor sensor (either 5.0 meters or 9.0 meters total length). Connect the gold ClickLoc fittings until they click firmly. Do not use standard pliers on the gold connector sleeves; apply only hand tension or a dedicated coaxial connector tool. Observe the minimum static bend radius of 25.4 mm (1.0 inch) to protect the internal coaxial dielectric layers from degradation.

Compliance and Certifications

• CSA: Approved for hazardous areas when connected with certified barriers.
• ATEX/IECEx: Zone 0, Zone 1, and Zone 2 intrinsically safe and non-sparking configurations.
• CE/RoHS: Compliant with European standard environmental restrictions.
