Description

The Bently Nevada 330730-080-02-00 is a high-performance 3300 XL 11mm extension cable, engineered as a critical component of the 3300 XL 11mm Proximity Transducer System. This cable provides the necessary link between the 11mm proximity probe and the Proximitor sensor, facilitating precise, non-contacting vibration and displacement measurements in fluid film bearing machinery. The system is designed to ensure signal integrity and accurate monitoring in demanding industrial environments.

Features

• ClickLoc Connectors: Features gold-plated brass ClickLoc connectors that lock into place, preventing accidental disconnection and ensuring reliable electrical continuity.
• Robust Construction: Utilizes 75 Ohm triaxial cable with fluoroethylenepropylene (FEP) insulation for superior durability and chemical resistance.
• System Compatibility: Specifically calibrated for the 3300 XL 11mm transducer system; ensures total system length matching for maintained accuracy.
• Connector Protection: Includes connector protectors to provide an environmentally sealed joint, preventing contamination from dust or moisture.

Applications

• Radial Vibration and Position: Monitors side-to-side shaft movement within bearings.
• Axial (Thrust) Position: Measures shaft axis movement to prevent internal contact.
• Differential Expansion: Monitors rotor-casing growth differences in steam turbines.
• Speed and Phase Reference: Functions as a Keyphasor sensor for tacho and zero-speed applications.
• Rod Drop/Position: Monitors reciprocating compressors for rider band wear.

Technical Specifications

Installation Guidelines

• System Matching: Ensure the total length of the probe and extension cable matches the calibrated Proximitor sensor system length to maintain measurement accuracy.
• Handling: Use caution when routing the cable to avoid sharp bends or mechanical stress that could damage the FEP insulation.
• Connection: Ensure ClickLoc connectors are fully seated and locked. Use connector protectors to seal the junction against environmental contaminants.
• EMI/RFI: While the 3300 XL system features improved immunity, avoid routing signal cables in parallel with high-voltage power lines or near high-frequency radio sources.
• Maintenance: Power down the monitoring system before disconnecting or replacing transducer components to prevent electrical transients.

FAQ

What is the 330730-080-02-00?

The 330730-080-02-00 is an 8.0-meter extension cable specifically designed for the Bently Nevada 3300 XL 11mm Proximity Transducer System used in critical machinery monitoring.

Can this cable be used with 8mm probes?

No. This cable is specifically engineered and calibrated for the 11mm transducer system. It is not interchangeable with 8mm or 5mm probe systems.

What is the purpose of the connector protectors?

The connector protectors (included in the -02 option) provide an environmentally sealed joint at the probe-to-cable connection, protecting the interface from moisture, oil, and dust ingress.
