Bently Nevada 330730-080-02-05 3300 XL 11mm Proximity Extension Cable

Product Overview

The Bently Nevada 330730-080-02-05 is an industrial-grade 8-meter extension cable engineered specifically for the 3300 XL 11mm proximity transducer system. It acts as the vital signal link that enables continuous, non-contact displacement and vibration monitoring on heavy rotating machinery.

Functional Description

This extension cable bridges the gap between the 11mm proximity probe tip and the Proximitor sensor unit. Because the 11mm sensor system provides an extended linear range compared to standard 8mm models, keeping the signal intact over long distances remains paramount. The cable accurately carries the high-frequency eddy current signals, converting physical target gaps into stable voltage outputs of 3.94 V/mm (100 mV/mil). As a result, monitoring systems receive a clean, undistorted feed to track asset health in real time.

Technical Characteristics

• Extended Range Capability: Supports the 11mm system’s wider measurement window for deeper gap tracking.
• Optimized Signal Scale: Preserves the calibrated scale factor of 3.94 V/mm (100 mV/mil) without signal loss.
• Industrial Shielding: Employs advanced insulation techniques to reject harsh electromagnetic noise in power plants.
• Environmental Security: Compatible with specialized connector protectors to block moisture, oil, and dust ingress.
• Standardization: Supports plant compliance initiatives by meeting the strict technical guidelines of API 670.
