Bently Nevada 330130-045-13-00 3300 XL Extension Cable

Product Overview

The 330130-045-13-00 is a specialized extension cable for the Bently Nevada 3300 XL proximity transducer system. This cable acts as the vital link between a 3300 XL proximity probe and a 3300 XL Proximitor® Sensor. Engineered for extreme industrial environments, this specific model features FluidLoc® technology to prevent moisture or oil from wicking through the cable and stainless steel armor to protect against mechanical crushing and abrasion.

In a standard vibration monitoring loop, the extension cable must be matched to the probe length to achieve a "Total System Length" (typically 5.0 or 9.0 meters). This ensures the electrical circuit is perfectly tuned for the eddy current measurement used to monitor shaft vibration and position.

Technical Configuration

The part number breakdown identifies the protective features and physical dimensions:

• Cable Length (045): 4.5 metres (14.8 feet). When paired with a 0.5-meter probe, this creates a 5.0-meter system.

• FluidLoc® Cable: Features a patented internal design that blocks the "wicking" effect, ensuring that if one end of the cable is exposed to oil or pressurized fluids, the liquid cannot travel through the cable into the Proximitor housing.

• Armored Protection: The cable is encased in flexible, interlocking stainless steel armor, providing superior crush resistance in areas with heavy foot traffic or sharp-edged machinery.

• Connector Protectors (13): Includes clear, removable sleeves at the connection points to prevent the ClickLoc™ connectors from vibrating loose and to provide environmental sealing.

• Non-Isolated Design: Standard coaxial construction optimized for high-frequency signal transmission with minimal loss.

Technical FAQs

Why is FluidLoc® important for my installation?

In many turbines and gearboxes, the probe end is submerged in lubricating oil. Standard cables can act like a "straw," allowing oil to seep through the internal gaps of the cable and eventually leak into the control cabinet. FluidLoc® seals the internal cable structure to prevent this.

Can I cut this cable to a shorter length if it's too long?

No. The 3300 XL system is a tuned resonant circuit. The capacitance and inductance of the cable are calculated into the vibration reading. Cutting the cable will change the impedance, causing significant errors in the vibration measurement or making the system completely non-functional.

Does this cable require a specific Proximitor?

Yes, this cable must be used with a 3300 XL Proximitor configured for a 5.0-meter system. Using it with a 9.0-meter Proximitor will result in incorrect scale factors and inaccurate data.

Engineering & Installation Guide

• Connector Integrity: When joining the probe to the extension cable, ensure the ClickLoc™ connectors "click" into place. Slide the connector protector over the junction to ensure it remains locked despite machine vibration.

• Avoid Sharp Bends: Although armored, the cable has a minimum bend radius. Forcing a sharp 90-degree bend can damage the internal coaxial dielectric, leading to "noisy" vibration signals.

• Conduit and Support: While the armor provides protection, the cable should still be supported by conduit or cable trays where possible. Avoid zip-tying the cable directly to high-voltage power lines to prevent electromagnetic interference (EMI).

• Grounding: The 3300 XL system typically expects a single-point ground at the Proximitor end. Ensure the armor is not inadvertently touching other grounded metal surfaces that could create a ground loop.
