Bently Nevada 330930-060-01-05 3300 NSv Extension Cable

Description

Cable Option 060 (6.0 meters length), Option 01 (stainless steel armor with FEP jacket), and Option 05 (multiple agency approvals) define the specific configuration of this 3300 NSv Extension Cable — 330930-060-01-05. This cable is designed to connect a 3300 NSv proximity probe to a 3300 XL NSv Proximitor Sensor, ensuring matching electrical length for tight-clearance and small-bore machine monitoring applications.

Unlike unarmored versions (Option 00) or uncoated armored versions (Option 02), this FEP-jacketed armored extension cable provides robust mechanical protection against physical abrasion and chemical resistance in harsh industrial environments. The 6.0 m length must be selected so that the combined length of the extension cable and the probe matches the required 5.0 m or 7.0 m system calibration of the corresponding Proximitor Sensor.

Features

• Option 060 specifies a total cable length of 6.0 meters (19.7 feet).
• Option 01 provides flexible stainless steel armor with a protective FEP outer jacket to prevent moisture and chemical ingress.
• Option 05 includes multiple international hazardous area certifications (CSA, ATEX, IECEx, NEPSI) for intrinsically safe and non-incendive environments.
• 75 ohm coaxial cable design ensures low signal attenuation and precise high-frequency response.
• Miniature coaxial ClickLoc connectors on both ends offer secure, vibration-resistant coupling without special tools.
• Compatible with 3300 NSv standard and reverse mount proximity probes and 3300 XL NSv Proximitor Sensors.

Applications

This extension cable is used in machinery protection systems to monitor shaft vibration and axial position in the following scenarios:

• Small-bore machinery and high-speed equipment with limited target clearance and small target geometry.
• Aeroderivative gas turbine installations where tight structural spaces require high-accuracy eddy-current transducers.
• Centrifugal compressors, pumps, and fans operating in industrial manufacturing facilities.
• Hydrocarbon processing, oil and gas production, and petrochemical plants requiring robust, armored, and certified instrumentation.

Installation Guidelines

• Maintain a minimum bend radius of 25.4 mm (1.0 in) along the entire cable run to avoid damaging the coaxial shielding or center conductor.
• Ensure that ClickLoc connectors are hand-tightened. Avoid using wrenches or pliers beyond the maximum recommended torque of 0.56 N m (5 in lb).
• Use connector protectors or silicone self-fusing tape (Bently Nevada part number 03200006) to seal the probe-to-cable connection from liquid and debris.
• Route the extension cable inside dedicated conduit or cable trays separated from high-voltage AC lines to prevent electrical noise coupling.
• Use physical cable clamps or ties to secure the armored jacket near connectors, eliminating mechanical stress on the ClickLoc interface.
