Bently Nevada 330930-065-04-05 3300 NSv Extension Cable

Description

Option 065 (6.5 m cable length) and Option 04 (stainless steel armor, FEP jacket, with connector protector) specify this 3300 NSv Extension Cable configuration — 330930-065-04-05. This configuration incorporates a physical protection package consisting of stainless steel armor and an outer Fluorinated Ethylene Propylene (FEP) jacket, along with an integrated connector protector at the male-female junction. The extension cable bridges the gap between the 3300 XL NSv proximity probe and the 330980 Proximitor Sensor, maintaining the 75-ohm coaxial transmission path for non-contact displacement measurements in small-bore machinery and high-speed turbomachinery installations.

This specific 6.5-meter cable length is designed to pair with a 0.5-meter proximity probe to construct a complete 7.0-meter system length, maintaining the system calibration required for accurate sensor operation. The armor and FEP jacket provide defense against mechanical wear, moisture, and chemical exposure in industrial environments, while the connector protector prevents liquids from entering the ClickLoc connections.

Features

• Option 065 specifies a 6.5-meter (21.3 feet) overall cable length, matching specific system length requirements.
• Option 04 delivers mechanical shielding with stainless steel armor, a chemical-resistant FEP jacket, and an integrated connector protector.
• Option 05 designates multiple agency approvals, allowing deployment in Class I, Division 2, and Zone 2 hazardous areas.
• Miniature coaxial ClickLoc connectors provide secure coupling without requiring specialized termination tools.
• Standard 75-ohm coaxial engineering provides stable, high-frequency transmission for non-contact displacement monitoring.

Applications

• Eddy-current displacement and vibration monitoring on high-speed rotating shafts.
• Small-bore machinery and aeroderivative gas turbines with limited installation clearances.
• Petrochemical, power generation, and gas transmission environments requiring Class I hazardous area certifications.
• Machinery protection systems needing physical resistance against mechanical wear, moisture ingress, and chemical exposure.

Installation Guidelines

Ensure that all coaxial connectors are completely clean and dry before mating. Align and connect the ClickLoc miniature coaxial fittings securely. Avoid kinking or exceeding the minimum bend radius of the armored cable during routing. Ensure the total length of the extension cable (6.5 m) combined with the proximity probe length (0.5 m) matches the calibrated 7.0-meter system configuration of the Proximitor Sensor. The integrated connector protector should be fully slid over the joint to protect the connection from moisture, turbine oil, and other contaminants.
