Bently Nevada 330930-065-03-00 3300 NSv Extension Cable

Description

Option 065 (6.5 meters cable length) and Option 03 (unarmored cable with connector protector) specify this 3300 NSv extension cable configuration — 330930-065-03-00.

Used within the 3300 XL NSv Proximity Transducer System, this 75 ohm coaxial cable provides the electrical connection between a 3300 NSv proximity probe and a 330980 Proximitor Sensor. The total system length (probe plus extension cable) must match the Proximitor Sensor's designed length configuration (such as 7.0 meters total when combined with a 0.5 meter probe). This specific unarmored version features a pre-installed fluorosilicone connector protector to guard the probe-to-cable junction against fluid ingress and particulate contamination in tight machinery clearances.

Compared to alternative armored variations, this unarmored configuration offers a smaller installation profile, ideal for routing through tight conduit runs or internal machine cavities. Because this SKU is ordered under Option 00 for agency approvals, it is selected for non-hazardous locations or applications where specialized regional certifications are not required.

Features

• 6.5-meter cable length (21.3 feet) for specific spatial configuration needs
• Unarmored design providing maximum routing flexibility with a 25.4 mm (1.0 in) minimum bend radius
• Gold-plated brass ClickLoc connectors ensuring positive engagement and resistance to vibration loosening
• Fluorosilicone connector protector pre-installed on the female end to prevent fluid contamination at the connector interface
• High-grade FEP jacket offering chemical resistance inside industrial machinery environments
• Low electrical capacitance of 69.9 pF/meter to maintain signal integrity over the measurement chain

Applications

• Radial vibration and axial position measurements in small-bore rotating machinery
• Aeroderivative gas turbine vibration monitoring
• Centrifugal compressors with limited target geometry and restricted installation clearances
• High-speed machinery requiring non-contact eddy current transducer systems

Installation Guidelines

• System Length Match: Ensure that the sum of the extension cable length (6.5 m) and the probe length (e.g., 0.5 m) equals the Proximitor Sensor total length calibration (7.0 m).
• Connector Tightening: Connect finger-tight. The maximum allowable connector torque is 0.56 N-m (5 in-lb) to prevent damage to the miniature coaxial threads.
• Bend Radius Limits: Maintain a bend radius of at least 25.4 mm (1.0 in) along all sections of the FEP jacket to prevent shielding degradation.
• Connector Insulation: Avoid routing connectors through conductive fluids or exposing them to high-pressure washdowns without additional protective sleeving or silicone self-fusing tape.
