Bently Nevada 330930-045-05-05 3300 NSv Extension Cable

Description

The 330930-045-05-05 is a 3300 NSv extension cable designed for use within the Bently Nevada 3300 XL NSv proximity transducer system. This specific configuration is defined by a 4.5-meter (14.8 feet) total cable length, protective stainless steel armor without an outer FEP jacket, an integrated fluorosilicone connector protector, and multiple international hazardous area approvals. It is engineered for industrial environments where space is highly restricted, and machinery shafts or targets are exceptionally small, requiring robust mechanical protection without adding unnecessary diameter or weight.

Unlike standard non-armored cables or variants equipped with heavy FEP jacketing, this configuration uses uncoated stainless steel armor to defend the internal coaxial media against physical cutting, pinch points, and abrasive wear. The integrated connector protector provides a reliable environmental seal over the ClickLoc miniature coaxial interface, preventing moisture, turbine oil, and other industrial contaminants from degrading the electrical signal. This extension cable connects a 3300 NSv proximity probe directly to a 330980 Proximitor sensor, establishing a complete calibrated signal path for dynamic vibration and position monitoring.

Features

• Cable Length Option: 4.5 meters (14.8 feet) provides precise physical reach for standard 5.0-meter or 7.0-meter system length layouts.
• Uncoated Armor Protection: Stainless steel armor provides high mechanical protection without the added bulk or thermal limitations of an outer plastic sheath.
• Sealed ClickLoc Junction: Features an integrated fluorosilicone connector protector that isolates the male-to-female connector mating face from fluid intrusion.
• ClickLoc Connectors: Gold-plated brass miniature coaxial connectors secure the connection with minimal signal impedance.
• Agency Approvals: Option 05 offers multiple hazardous area certifications, including ATEX, IECEx, and CSA, for deployment in intrinsically safe or non-sparking zones.

Applications

This extension cable is used in machinery diagnostics and protection systems across various demanding industrial installations:

• High-speed centrifugal compressors and turbochargers with limited casing access.
• Aeroderivative gas turbines and industrial steam turbines.
• Fluid-film bearing machinery where small-shaft geometries restrict the use of larger standard probes.
• Vibration and thrust position monitoring in hazardous chemical and hydrocarbon processing facilities.

Installation Guidelines

To establish safe and reliable performance, please follow these industrial installation practices:

• Ensure that the sum of the probe length and the extension cable length exactly matches the calibrated total length of the Proximitor sensor (typically 5.0 meters or 7.0 meters).
• Maintain a minimum bend radius of 25.4 mm (1.0 in) along all sections of the armored cable to avoid damaging the internal coaxial core.
• Slide the fluorosilicone connector protector firmly over the ClickLoc coaxial connection to seal the interface and shield it from moisture or machine oil.
• Keep the cable isolated from high-voltage conduit routing to prevent electromagnetic noise from interfering with the low-voltage vibration signal.

Compliance and Certifications

Under Option 05, this component carries several international certifications for safe operation:

• ATEX / IECEx: Certified for intrinsically safe (Ex ia IIC Ga/Dc) and non-sparking/ec (Ex nA/ec IIC Gc) hazardous environments.
• North American (CSA/cNRTLus): Approved for Class I, Zone 0/2, Groups A, B, C, D and Class II, Groups E, F, G.
• Functional Safety: SIL 2 (HFT=0) and SIL 3 (HFT=1) certified when integrated within an approved safety-instrumented loop.
• RoHS: Meets European Community Directive 2011/65/EU and Chinese environmental safety standards.
