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.

Parameter Analysis

The 330730-040-11-05 extension cable is engineered for high reliability in harsh conditions. Its low capacitance (69.9 pF/m) ensures minimal signal degradation over the 4.0-meter length. The armored stainless steel construction with FEP jacket provides excellent mechanical and chemical resistance, while the FluidLoc option prevents fluid ingress. The cable supports system lengths of 5 or 9 meters when combined with probes, and its temperature range of -51°C to +177°C suits extreme environments.

Application Scenarios

This extension cable is ideal for vibration monitoring on rotating machinery including turbines, compressors, pumps, and other industrial equipment. It is commonly used in oil, gas, power generation, and petrochemical plants where reliable condition monitoring is critical.

Installation Guide

Installation must follow the Bently Nevada 3300 XL system guidelines. Ensure the cable is routed without sharp bends and protected from mechanical damage. Use the provided silicone tape or connector protectors at connections, especially in humid or oily environments. The cable connects between the probe and the Proximitor sensor; verify the total system length (probe + extension) is either 5 or 9 meters for proper calibration.

Compatibility

The 330730-040-11-05 is compatible with Bently Nevada 3300 XL 11 mm probes and 3300 XL Proximitor sensors. It is designed for use with 3300 series monitoring systems. Always confirm system length requirements before installation.

Maintenance Advice

Regularly inspect the cable and connectors for signs of wear, corrosion, or fluid contamination. Clean connectors with approved solvents and reapply silicone tape if used. Check that the armor is intact and free of cracks. For long-term reliability, replace any damaged cable immediately.

Procurement Advice

When ordering, verify the model number 330730-040-11-05 to ensure correct length and options. Consider purchasing spare cables to minimize downtime. Ensure the supplier is an authorized Bently Nevada channel to guarantee genuine parts and warranty support.
