Bently Nevada 330903-00-04-05-02-CN 3300 NSv Proximity Probe

Description

The 330903-00-04-05-02-CN is a 3300 XL NSv proximity probe designed for critical machinery monitoring in applications with restricted target geometry or tight installation spaces. This 5 mm eddy-current transducer system is optimized for small-bore machinery, aeroderivative turbines, and high-speed equipment where standard 8 mm probes cannot be effectively gapped. This specific configuration features an M8x1 thread (330903), 0.0 in unthreaded length (Option 00), 0.4 in case length (Option 04), 0.5 m total system length (Option 05), and a standard miniature ClickLoc connector (Option 02).

The 3300 XL NSv system is engineered to deliver reliable radial vibration and axial position measurements on shafts smaller than 51 mm or on targets smaller than 15 mm. This unit includes the -CN suffix, signifying a dedicated China hazardous area approval package, ensuring compliance with local NEPSI and CCC certification standards for operation in classified environments.

Features

• M8x1 thread non-armored probe body
• Designed for reduced target area and tight clearance applications
• Compatible with 3300 XL NSv Proximitor Sensor and extension cable
• Gold-plated brass ClickLoc connectors to prevent loosening
• Patented TipLoc molding for robust probe tip-to-body bonding
• Includes -CN China hazardous area approval package (NEPSI/CCC)

Applications

• Radial vibration and radial position measurements
• Axial (thrust) position measurements
• Tachometer and zero speed measurements
• Phase reference (Keyphasor) signal acquisition
• Centrifugal air, refrigeration, and process gas compressors

Installation Guidelines

Ensure proper probe gapping according to the 3300 XL NSv documentation to maintain linear output. Use standard Bently Nevada connector protectors on the probe-to-extension cable interface to prevent liquid ingress. Install the Proximitor Sensor in a protected enclosure with a degree of protection of at least IP54. Consult the system manual for hazardous area installation drawings (141092/140979) to ensure intrinsic safety or non-incendive compliance.

Compliance and Certifications

This product includes the -CN suffix, designating compliance with China hazardous area approval requirements, including NEPSI and CCC certifications. The system is also designed to meet CE standards for EMC directives and RoHS requirements.
