Bently Nevada 330130-085-03-05 3300 XL Armored Extension Cable

Product Overview

The Bently Nevada 330130-085-03-05 is a premium 3300 XL standard extension cable designed to bridge the connection between a proximity probe and a Proximitor® sensor. This 8.5-metre cable is engineered for maximum signal integrity in critical vibration monitoring systems. Featuring robust stainless steel armor and integrated connector protectors, it provides superior mechanical shielding and environmental resistance. At approximately 0.29 kg, it is optimized for high-reliability applications in power plants, refineries, and industrial processing facilities.

Technical Specifications

Installation & Engineering Guide

To maintain the precision of the 3300 XL transducer system, follow these engineering requirements:

• System Length Matching: This 8.5m cable is typically used with a 0.5m or 1.0m probe to reach a total system length of 9.0m. Ensure your Proximitor® sensor is calibrated specifically for a 9-metre system.
• Armor Handling: The stainless steel armor provides crush resistance. However, ensure the 0.29 kg cable does not put excessive strain on the Proximitor® terminals. Secure the armor with proper conduit clips.
• Connector Protection: The -03 option includes protectors. Ensure these are properly seated to prevent moisture or oil ingress at the probe-to-extension cable junction.
• Bend Radius: Do not exceed the 30 mm minimum bend radius. Kinking the armored cable can cause internal coaxial damage and lead to erratic vibration readings.

Engineering Advantages

• ClickLoc™ Connectivity: Features gold-plated miniature coaxial connectors for a secure, low-resistance connection that resists loosening under machine vibration.
• Enhanced Shielding: With a 90 dB shielding effectiveness, this cable minimizes EMI/RFI interference, ensuring clear signal transmission even near high-voltage motor leads.
• Hazardous Area Ready: The -05 approval option makes this cable suitable for globally regulated explosive atmospheres without additional certification steps.
• Corrosion Resistant Armor: The stainless steel protective layer ensures durability in environments exposed to caustic turbine oils and steam.

Technical FAQs

Q1: What is the total length of the 330130-085-03-05?
A1: The cable itself is 8.5 metres long. When paired with a standard Bently Nevada proximity probe, it completes the electrical circuit for the Proximitor sensor.

Q2: Why is the 0.29 kg weight important for installation?
A2: The 0.29 kg weight indicates a balance between heavy-duty mechanical armor and the flexibility needed for routing through complex machinery internals.

Q3: Can I cut this cable to a shorter length?
A3: No. Bently Nevada extension cables are factory-calibrated to specific electrical lengths. Cutting or splicing the cable will change the impedance and invalidate the vibration data.
