Parameter Analysis

The 330730-080-02-00 extension cable is engineered with low capacitance (69.9 pF/m) to minimize signal loss over its 8-meter length, ensuring accurate transmission of eddy-current signals. The FEP insulation provides excellent thermal stability and chemical resistance, allowing operation in extreme temperatures. The gold-plated brass ClickLoc connectors ensure a secure, vibration-proof connection, while the optional connector protectors add defense against humid or moist environments. The cable’s robust construction, including a 330 N pull strength at the probe connection, ensures long-term reliability.

Application Scenarios

This extension cable is ideal for use in vibration monitoring systems on turbines, compressors, pumps, and other rotating machinery. It is commonly deployed in industries such as power generation, oil and gas, petrochemical, and manufacturing, where continuous condition monitoring is critical to prevent unplanned downtime. The 330730-080-02-00 is compatible with 3300 XL 11 mm probes and Proximitor sensors, forming a complete transducer system for shaft vibration and position measurement.

Installation Guide

Installation of the 330730-080-02-00 is straightforward. Connect the extension cable between the probe and the Proximitor sensor using the ClickLoc connectors, ensuring they lock securely into place. For environments with high humidity, use the provided silicone tape or connector protectors to seal the connections. Route the cable away from high-temperature surfaces and avoid sharp bends to prevent damage. The cable is designed for a maximum field wiring length of 305 meters (1,000 feet) between the Proximitor and monitor.

Compatibility

The 330730-080-02-00 is part of the 3300 XL series and is compatible with 3300 XL 11 mm probes (including armored and unarmored versions) and 3300 XL Proximitor sensors. It is also compatible with Bently Nevada 3500 monitoring systems when used with appropriate Proximitor sensors. The extension cable is designed to work with standard 75 Ω triaxial systems.

Maintenance Advice

Regularly inspect the cable for signs of wear, cuts, or abrasion, especially in high-vibration areas. Check that all connectors are tight and free of corrosion. If the cable is exposed to oil or moisture, clean the connectors with a suitable solvent and ensure protective covers are in place. The cable is designed for long service life, but periodic testing of capacitance and resistance can help verify integrity.

Procurement Advice

When ordering the Bently Nevada 330730-080-02-00, verify the cable length (8.0 meters) and connector option (standard with protectors) to ensure it meets your system requirements. Consider purchasing spare cables to minimize downtime. For applications with special needs, such as armored cable or fluid-blocking options, consult your TenBN representative for alternative models. Always purchase from authorized channels to guarantee genuine Bently Nevada quality.
