Are 3300 series and 3500 series modules interchangeable?

In general, 3300 and 3500 series modules are not directly interchangeable because the two systems use different racks, power supplies, and communication architectures. However, many sensors such as proximity probes and extension cables remain compatible. If you are migrating from 3300 to 3500, contact us — we will recommend the right retrofit path and compatible mounting options.

Do you stock spare parts for discontinued 3300/3500 series models?

Yes, we maintain a rotating stock of popular 3300 and 3500 series modules, including several models that Bently Nevada has discontinued. If a module is no longer manufactured, we can help you find a compatible drop-in replacement or an enhanced retrofit option, and we also offer fast emergency supply for critical outages.

How can I get a quote or a retrofit plan?

The fastest way is to use the inquiry cart on any product page, or submit a request through the contact channels on our site. Tell us the model numbers you need and your target quantities. Our team will respond within one business day with pricing, lead time, and — if you are replacing a discontinued model — a compatible retrofit recommendation.

Are your Bently Nevada products genuine and factory-new?

Yes. All modules, probes, and accessories we supply are brand new and original Bently Nevada products, sourced through an authorized channel. Every item comes with its factory serial number and full warranty. We never sell refurbished or cloned parts, so you can rely on the same quality, accuracy, and long service life as factory-direct supply.

Bently Nevada 330730-040-10-00 3300 XL 11 mm Extension Cable

High-performance 4.0-meter FluidLoc extension cable for 3300 XL proximity systems, ensuring reliable vibration monitoring.

Product Introduction

The Bently Nevada 330730-040-10-00 is a 3300 XL 11 mm Extension Cable designed for use with 3300 XL proximity probes. 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. Manufactured in the U.S.A., this cable ensures reliable signal transmission for condition monitoring applications.

Parameter Analysis

The 330730-040-10-00 extension cable is engineered for minimal signal loss and high reliability. Its low capacitance (69.9 pF/m) ensures accurate signal transmission over the 4-meter length. The FluidLoc option provides a sealed pathway, preventing liquid ingress that could compromise measurement integrity. The cable’s temperature range (-51°C to +177°C) makes it suitable for harsh industrial environments.

Application Scenarios

This extension cable is ideal for use in rotating machinery such as turbines, compressors, and pumps. It connects 3300 XL 11 mm proximity probes to extension cables or proximitors, enabling vibration and position monitoring. The FluidLoc option is particularly beneficial in applications where oil or other process fluids are present, as it prevents leakage through the cable interior.

Installation Guide

When installing the 330730-040-10-00, ensure the probe-to-extension cable connection is properly sealed. Silicone tape is provided with each cable and can be used instead of connector protectors; however, it is not recommended where the connection will be exposed to turbine oil. For humid environments, connector protectors are recommended for enhanced environmental protection. Always follow the manufacturer’s guidelines for routing and securing the cable.

Compatibility

The 330730-040-10-00 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. Field wiring between the Proximitor and monitor can be up to 305 meters (1,000 feet) using three-conductor shielded triad cable.

Maintenance Advice

Regularly inspect the cable for damage, especially at connectors. Ensure connectors are clean and dry. If the cable is exposed to harsh conditions, consider using armored versions for added protection. Periodically verify the electrical characteristics (capacitance and resistance) to ensure optimal performance.

Procurement Advice

When ordering the 330730-040-10-00, verify the model number to ensure it matches your system requirements. Confirm the cable length and connector option are correct for your application. Consider purchasing spare cables to minimize downtime. For assistance, contact TenBN, an authorized channel for Bently Nevada products.
