Bently Nevada 330930-065-01-00 3300 NSv Extension Cable

Description

Option 065 (6.5 meters length) and Option 01 (stainless steel armor with FEP jacket) define this 3300 NSv extension cable configuration — 330930-065-01-00. This coaxial cable extends the measurement loop length of 3300 NSv proximity probes to 330980 Proximitor sensors in non-contact displacement and vibration monitoring systems. It operates in small-bore machinery, aeroderivative turbines, and gearboxes where tight clearance geometries restrict probe diameters.

Unlike the standard unarmored configuration (Option 00), this variant utilizes protective stainless steel armor and an outer fluorinated ethylene propylene (FEP) jacket, providing physical shielding against abrasion, mechanical impact, and chemical exposure. Option 00 specifies standard general-purpose approvals, suitable for environments where hazardous area agency certification is not required.

Features

• Option 065 specifies a total cable length of 6.5 meters (21.3 feet) to establish the correct impedance loop for the transducer system.
• Option 01 provides stainless steel armor and a protective FEP outer jacket for robust mechanical and chemical shielding.
• Option 00 indicates standard industrial configuration without additional hazardous area agency certifications.
• Gold-plated brass ClickLoc coaxial connectors lock securely in place to eliminate connector loosening caused by high-vibration machinery.
• Directly compatible and interchangeable with previous-generation 3300 RAM proximity probe and extension cable systems.

Applications

• Centrifugal and axial process compressors
• Small-bore rotating machinery with tight mechanical clearances
• Aeroderivative gas turbines and high-speed auxiliary equipment
• Gearbox shaft radial vibration and axial thrust position measurements
• Power generation steam and gas turbines in non-hazardous operating areas

Installation Guidelines

• Routing and Support: Route the armored cable through dedicated conduit or secure it to structural components using cushioned brackets. Maintain a minimum bend radius of 25.4 mm (1.0 in) along the run to protect the coaxial core from degradation.
• Connection Integrity: Hand-tighten the gold-plated ClickLoc coaxial connectors until they click and lock. Avoid utilizing tools for standard tightening as excessive torque can damage the connector seals.
• Environmental Protection: Cover the probe-to-extension cable connection with silicone self-fusing tape or dedicated connector protectors to block fluid or moisture intrusion. Do not apply silicone tape in applications with direct exposure to hot turbine oil.
• Shield Grounding: Connect the cable shield exclusively at the Proximitor sensor terminal strip. Do not ground both ends of the cable shield to avoid grounding loop interference.

Compliance and Certifications

This standard general-purpose configuration (Option 00) is designed for non-hazardous industrial machinery environments where specialized explosion-proof or intrinsically safe agency certifications are not required.
