Bently Nevada 330930-060-00-05 3300 NSv Extension Cable

Description

A 6.0 m unarmored coaxial cable (Option 00) with multiple hazardous area approvals (Option 05) defines the 330930-060-00-05 3300 NSv extension cable configuration. This physical variant provides the intermediate connection between a 3300 NSv proximity probe and a 3300 XL NSv Proximitor sensor, completing a 7.0 m transducer system loop when matched with a 1.0 m probe. By omitting external stainless steel armor, this configuration maintains high cable flexibility and a reduced outer diameter, which facilitates routing through tight protective conduits or complex cable trays.

In contrast to sibling configurations like the armored 330930-060-01-05 or models utilizing integrated connector protectors, the unarmored 330930-060-00-05 employs a standard outer jacket over its shielded coaxial core. The system is used for non-contact eddy-current displacement measurements on industrial rotating machinery where installation clearance is restricted, target geometries are small, or standard-bore proximity systems cannot physically fit.

Features

• Option 060 specifies a 6.0-meter (19.7 feet) physical cable length, pairing with a 1.0 m proximity probe to form a 7.0 m system length.
• Option 00 provides a flexible, unarmored coaxial cable structure to maximize ease of routing in tight spaces.
• Option 05 multiple approvals package permits installation in international hazardous area zones.
• Gold-plated brass coaxial ClickLoc connectors provide low-resistance electrical contact and secure coupling without tools.
• FEP outer insulating jacket resists moisture, chemical exposure, and elevated operating temperatures.

Applications

This cable is used in rotating machinery monitoring systems, including:

• Aeroderivative gas turbines and compact industrial turbines with limited internal clearances.
• Radial shaft vibration and axial position measurements in small-bore machinery.
• High-speed centrifugal compressors and turbocompressors requiring tight spatial mounting.
• Fluid film bearing clearance monitoring on auxiliary pumps, fans, and generators.

Ordering Information

Technical Specifications

Connections and Interfaces

The cable features one miniature male ClickLoc coaxial connector on one end (connects to the female connector of the 3300 NSv proximity probe) and one miniature female ClickLoc coaxial connector on the other end (connects to the male connector on the 3300 XL NSv Proximitor Sensor). Proper torque should be restricted to finger tight plus a maximum of 0.56 N m (5 in lb) torque during assembly.

Installation Guidelines

• Ensure the combined physical length of the proximity probe and the extension cable matches the calibrated system length of the Proximitor Sensor (e.g., 1.0 m probe plus 6.0 m extension cable for a 7.0 m system).
• Maintain a minimum bend radius of 25.4 mm (1.0 in) along all sections of the cable run to prevent impedance mismatch or conductor damage.
• Avoid routing the unarmored cable across sharp metal edges or high-abrasion surfaces without appropriate protective conduit.
• Verify that the coaxial ClickLoc connectors are fully clean and dry before mating. Secure the connection finger-tight to ensure robust contact.
• In environments with high moisture or liquid spray, protect the connectors using a connector protector kit or self-fusing silicone tape to prevent fluid ingress.
