Bently Nevada 330730-040-10-05 3300 XL 11 mm Extension Cable

Product Introduction

The Bently Nevada 330730-040-10-05 is a 3300 XL 11 mm Extension Cable, designed for use with 3300 XL proximity transducers. This 4.0-meter (13.1 feet) cable features the FluidLoc option, which prevents oil and other liquids from leaking out of the machine through the cable’s interior. It comes with multiple agency approvals, ensuring compliance with international standards. Manufactured in the U.S.A., this cable is an essential component for reliable vibration and position monitoring in critical rotating machinery.

Parameter Analysis

The 330730-040-10-05 extension cable is engineered to maintain signal integrity over its 4.0-meter length, with low capacitance (69.9 pF/m) and precise resistance values. The FluidLoc option ensures that no liquids can ingress through the cable, making it ideal for environments where oil or moisture is present. The cable operates over a wide temperature range, from -52°C to +177°C, suitable for harsh industrial conditions. The gold-plated connectors provide excellent conductivity and corrosion resistance.

Application Scenarios

This extension cable is used in conjunction with 3300 XL 11 mm proximity probes and Proximitor sensors to measure shaft vibration and position in rotating machinery such as turbines, compressors, pumps, and other critical equipment. It is suitable for applications requiring reliable performance in humid or liquid-exposed environments, thanks to the FluidLoc option.

Installation Guide

When installing the 330730-040-10-05 extension cable, ensure that the probe-to-extension cable connection is properly protected. Silicone tape is provided with each cable and can be used instead of connector protectors, but it is not recommended where the connection will be exposed to turbine oil. For humid environments, connector protectors are recommended for additional protection. The cable must be routed carefully to avoid sharp bends and mechanical stress, respecting the maximum tensile strength of 330 N (75 pounds) at the probe case and 270 N (60 pounds) at the connectors.

Compatibility

This extension cable is compatible with Bently Nevada 3300 XL 11 mm proximity probes and 3300 XL Proximitor sensors. It is designed for system lengths of 5 or 9 meters including the extension cable. It can be used with the 3300 and 3500 monitoring systems.

Maintenance Advice

Regularly inspect the cable and connectors for signs of wear, damage, or contamination. Keep connectors clean and dry. If the cable is exposed to harsh environments, periodic checks are recommended. Ensure that the cable is not subjected to excessive tension or bending during operation.

Procurement Advice

When ordering the Bently Nevada 330730-040-10-05, verify the model number to ensure it matches your system requirements. Consider the cable length and options needed for your specific application.
