Bently Nevada 330930-045-01-00 3300 NSv Uzatma Kablosu

Description

The Bently Nevada 330930-045-01-00 is a 4.5-meter (14.8 feet) 3300 NSv Extension Cable engineered to provide precise signal path connectivity within the 3300 XL NSv Proximity Transducer System. This unit is specifically configured for mid-range distance requirements where standard 4.0m or 5.0m cabling options create excessive or insufficient slack, necessitating a more exacting cable run in complex machinery cabinets.

This specific model utilizes a ruggedized architecture featuring AISI 302 stainless steel armor without an FEP outer jacket. This construction balances physical durability—protecting the coaxial core against localized mechanical abrasions—with the necessary flexibility required for tight-radius routing inside compressor skids or turbine enclosures. It serves as a vital bridge in systems where the Proximitor Sensor is located in a protected, remote junction box away from the primary measurement point, ensuring that low-level eddy-current signals remain shielded from localized electromagnetic noise.

Features

• 4.5m Length Precision: Provides an intermediate length option to optimize cable management and minimize signal attenuation in custom-configured monitoring loops.
• Stainless Steel Armor Protection: Includes flexible AISI 302 stainless steel armor, enhancing crush resistance and shielding against sharp installation edges without the additional bulk of an outer FEP jacket.
• High-Frequency Stability: Optimized to maintain linear signal response (voltage-to-gap) across the extended 4.5m span, critical for phase-sensitive applications like Keyphasor signal processing.
• ClickLoc Mechanical Integrity: Equipped with field-proven, gold-plated brass ClickLoc connectors that provide a secure, vibration-proof latch, preventing signal intermittent behavior caused by connector fretting.
• Seamless Field Integration: Fully compliant with existing 3300 NSv hardware, allowing for easy integration into high-density probe arrays where routing space is at a premium.

Applications

• Precision Compressor Monitoring: Radial vibration and thrust position sensing on small-shaft turbomachinery where the sensor housing must be displaced by exactly 4.5 meters from the probe tip.
• Advanced OEM Skids: Integration into pre-engineered compressor skids that demand specific, standardized cable lengths to ensure consistent signal timing across multiple machine trains.
• Signal Routing in Dense Conduits: Deployment in cable-crowded environments where armored protection is essential for cable longevity, yet the absence of a bulky FEP jacket is preferred for improved pull-through performance.
• Tachometer Array Synchronization: Managing phase reference signal paths in multi-probe tachometer systems requiring balanced cable lengths to avoid phase synchronization errors.

Technical Specifications

Installation Guidelines

• Calibration Verification: Verify that the 3300 XL NSv Proximitor Sensor is configured for a 4.5m extension cable length (often part of a 5.0m or 7.0m total system calibration) to ensure measurement accuracy.
• Armor Handling: When routing the stainless steel armored cable, ensure the armor ends are properly seated to prevent fraying and to maintain the electrical continuity of the shield path.
• ClickLoc Engagement: Use manual pressure to lock the ClickLoc connectors until a distinct click is felt. Do not apply thread-locking compounds to the connectors.
• Cable Radius Maintenance: Maintain at least a 25.4 mm bend radius. Excessively tight bends may deform the coaxial core, causing local impedance mismatches that manifest as "noise" in the vibration data.

Compliance and Certifications

• EMC Directive: Designed to withstand industrial electromagnetic environments (EN 61000-6-2/4).
• RoHS/China RoHS: Environmentally compliant with international hazardous substance directives.
• Safety Standards: Components are designed to support SIL-rated safety instrumented systems (SIS) when used with appropriate certified Proximitor modules.
