Product Overview

The Bently Nevada 330730-080-01-05 is an 8.0 m extension cable used in the 3300 XL 11 mm proximity transducer channel to connect an 11 mm probe to its corresponding Proximitor sensor. The extension cable is a required system element that helps maintain the specified electrical characteristics of the transducer channel, supporting stable gap voltage and dynamic vibration signal transfer in machinery protection and condition monitoring installations.

This cable is commonly selected for upgrade projects where older 11 mm/14 mm proximity systems are being replaced by the 3300 XL 11 mm platform. For best practice channel performance, proximity system upgrades are performed as a complete set (probe, extension cable, and Proximitor), and the monitoring system configuration should be verified to ensure the 3300 XL 11 mm system is supported.

Key Technical Characteristics

Integration notes

• Channel accuracy depends on using the correct 11 mm probe, the correct extension length, and the matching Proximitor sensor for the same system length.

• When used with a 3500 Monitoring System, ensure the configuration software and module options support the 3300 XL 11 mm transducer system.

Industrial Applications

• Shaft vibration and displacement monitoring on turbines, compressors, pumps, and generators using 3300 XL 11 mm proximity channels

• Retrofit and modernization work replacing older proximity transducer families where an 8 m system cable run is required

• Machine casing and bearing housing installations where armored construction reduces risk of cable damage during maintenance

• Long cable routing inside skids and control cabinets while maintaining transducer channel electrical performance
