Bently Nevada 330930-040-00-CN 3300 NSv Extension Cable

Product Introduction

The Bently Nevada 330930-040-00-CN is a 3300 NSv extension cable designed for use with 3300 XL NSv Proximitor Sensors. This genuine Bently Nevada part is made in the U.S.A. and provides a 4.0 meter (13.1 feet) cable length. The connector and cable option is 00, meaning this unit is supplied without stainless steel armor. The CN agency approval option indicates country-specific approvals; the CN Approvals Option Quick Reference Guide and Field Notification Letter are available in the download section.

Parameter Analysis

The 330930-040-00-CN uses a 75 Ω coaxial FEP-insulated construction. Extension cable DC resistance is 0.220 Ω/m (0.067 Ω/ft) for the center conductor and 0.066 Ω/m (0.020 Ω/ft) for the shield. Typical extension cable capacitance is 69.9 pF/m (21.3 pF/ft). The linear range is 1.5 mm (60 mils), beginning at approximately 0.25 mm (10 mils) from the target and extending from 0.25 to 1.75 mm (10 to 70 mils), corresponding to approximately -1 to -13 Vdc. The recommended gap setting is 1.0 mm (40 mils). Maximum rated tensile strength is 220 N (50 lb) at the probe case to probe lead, at the probe lead to extension cable connectors, and at the probe case to stainless steel armor.

Application Scenarios

This extension cable is intended for 3300 NSv proximity monitoring systems used on turbines, compressors, pumps, and other rotating machinery. It connects the eddy-current probe to the Proximitor Sensor, allowing vibration and position signals to be transmitted to the monitoring system.

Installation Guide

Make sure that the extension cable length and the probe length, when added together, equal the Proximitor Sensor total length. Because this model is supplied without stainless steel armor, handle the cable carefully and avoid sharp edges, excessive pulling, or tight bends. Follow the Bently Nevada installation instructions and use the recommended field wiring practices.

Compatibility

The 330930-040-00-CN is part of the 330730/330930 series and is compatible with 3300 XL NSv Proximitor Sensors. Field wiring between the 3300 XL NSv Proximitor Sensor and the monitor should use 0.2 to 1.5 mm² (16 to 24 AWG) conductors, or 0.25 to 0.75 mm² (18 to 23 AWG) with ferrules. A three-conductor shielded triad cable is recommended, with a maximum length of 305 meters (1,000 feet).

Maintenance Advice

Periodically inspect the gold-plated brass connectors and keep them clean and free of contamination. If signal quality issues occur, verify the extension cable DC resistance and capacitance against the published values. Do not exceed the maximum rated tensile strength of 220 N (50 lb). Store and operate the cable within the specified temperature range.

Procurement Advice

Confirm that the model number is 330930-040-00-CN, with cable length option 040 (4.0 meters) and connector and cable option 00 without stainless steel armor. Verify that the CN approval option matches your installation location. When ordering, ensure the extension cable length plus probe length equals the Proximitor Sensor total length.
