Product Overview

The 330703-000-060-10-02-CN is a high-precision coaxial extension cable designed for the Bently Nevada 3300 XL 11 mm Proximity Transducer System. This component acts as the essential bridge between the non-contacting 11 mm probe and the Proximitor signal conditioner. Engineered to transmit sensitive eddy current signals without loss, this 6.0-meter cable maintains the strict electrical impedance required for the 11 mm system's extended measurement range. It is particularly critical for applications where the monitoring rack is located at a significant distance from the machinery, ensuring that vibration and position data remain accurate and free from industrial electromagnetic interference.

Technical Performance and Signal Integrity

This extension cable is optimized for the larger 4.0 mm (160 mil) linear measurement envelope typical of 11 mm transducer systems:

• Consistent Impedance: Specifically tuned to prevent signal reflection and attenuation over its 6.0-meter length, preserving the system scale factor of 3.94 V/mm (100 mV/mil).

• ClickLoc Connectivity: Equipped with gold-plated, miniature coaxial ClickLoc connectors that provide a self-locking, vibration-proof interface for maximum electrical contact.

• Environmental Shielding: High-grade fluoropolymer insulation protects the internal conductor from moisture ingress, synthetic lubricants, and chemical exposure commonly found in refineries and power plants.

• Thermal Range: Rated for continuous operation in extreme environments from -51°C to +177°C (-60°F to +350°F).

• Flexibility: Features a minimum bend radius of 25.4 mm (1.0 inch), allowing for complex routing through protective conduits and cable trays.

Industrial Asset Applications

The 330703-000-060-10-02-CN is a vital component for Turbine Supervisory Instrumentation (TSI) on high-capital rotating assets, including:

• Large Steam and Gas Turbines: Monitoring axial thrust position and thermal growth where a wider linear range is required.

• Hydroelectric Power Units: Tracking shaft centerline motion and radial vibration on large-diameter vertical and horizontal shafts.

• Heavy-Duty Compressors: Delivering reliable displacement data for critical process air and gas compressors in the petrochemical industry.

• Industrial Gearboxes: Measuring internal shaft clearances and vibration levels in high-torque power transmission systems.
