Bently Nevada 330930-045-00-05 3300 NSv Extension Cable

Description

330930-045-00-05 specifies this 3300 NSv extension cable configuration featuring a 4.5-meter (14.8 ft) length, unarmored standard coaxial construction, and Option 05 Multiple Approvals. This configuration provides a stable electrical connection between 3300 NSv proximity probes and 330980 Proximitor sensors, facilitating precise transmission of high-frequency eddy-current signals in tight clearance machinery environments.

This extension cable is manufactured with a 75-ohm coaxial design without stainless steel armor, offering maximum flexibility for easy routing through conduits and non-abrasive machine runs compared to armored variants (such as Options 01 and 02). With its 4.5-meter length, it is typically paired with a 0.5-meter proximity probe to form a calibrated 5.0-meter total system length, satisfying the precise capacitance requirements of the Proximitor sensor.

Features

• 4.5-meter (14.8 ft) cable length (Option 045) optimized for standard 5.0 m system configurations.
• Flexible unarmored coaxial cable (Option 00) for simplified installation in tight pathways.
• Option 05 Multiple Approvals, certified for safe use in CSA, ATEX, and IECEx hazardous areas.
• Gold-plated brass coaxial connectors ensuring stable connection integrity and minimal signal loss.
• 75-ohm characteristic impedance designed to maintain precise transducer performance.

Applications

• Aeroderivative gas turbines and high-speed industrial compressors with restricted target areas.
• Small-bore machinery requiring radial vibration or axial position monitoring.
• Environments utilizing non-armored casing runs where protection from extreme abrasion is not required.
• Hazardous industrial locations requiring extensive global explosion-proof certifications.

Installation Guidelines

• Always verify that the sum of the extension cable length (4.5 m) and the matching probe length (0.5 m) equals the Proximitor sensor total system length (5.0 m).
• Maintain a minimum bend radius of 25.4 mm (1.0 in) along all parts of the cable run to prevent impedance changes and physical degradation.
• Hand-tighten the coaxial connectors; do not use pliers or other tools that could exceed the maximum recommended torque limit of 0.56 N-m.
• Install silicone self-fusing tape or connector protectors over the probe-to-extension cable junction if exposed to fluids or moisture.
