Bently Nevada 330904-09-17-05-01-05 3300 XL NSv Proximity Probe

Description

The 330904-09-17-05-01-05 is a 3300 XL NSv proximity probe designed for machinery monitoring applications involving reduced target areas and tight clearances. This Near-field (NSv) transducer configuration features a 0.9 inch unthreaded length (Option 09), a 1.7 inch case length (Option 17), and a 0.5 meter total length (Option 05). The probe terminates with a miniature coaxial ClickLoc connector (Option 01) and includes Agency Approval for hazardous locations (Option 05: CSA, ATEX, IECEx).

The 3300 XL NSv system is engineered specifically for applications where standard 3300 XL 8 mm probes are too large. It is optimized for use with the 330980 NSv Proximitor Sensor and 330930 extension cable to provide accurate non-contact displacement measurements on high-speed equipment, small-bore machinery, and aeroderivative turbines with limited target geometry. The system ensures signal integrity through the proprietary ClickLoc connector interface and standard coaxial cabling.

Features

• NSv Transducer Design: Optimized for small-bore machinery and restricted target areas where standard proximity probes cannot maintain linear output.
• ClickLoc Connector: Miniature coaxial connector system provides a secure, reliable interface that prevents accidental disconnection during operation.
• Hazardous Area Approval (Option 05): Certified for use in hazardous environments, complying with CSA, ATEX, and IECEx safety standards.
• Compact Form Factor: Engineered for tight mechanical envelopes with 1.7 inch case length and 0.9 inch unthreaded length for precise installation.
• System Compatibility: Requires pairing with 330980 NSv Proximitor and 330930 extension cable for proper system linearity and calibration.

Applications

• Aeroderivative gas turbines
• Small-bore machinery vibration monitoring
• High-speed centrifugal compressors
• Equipment with limited target surface geometry
• Shaft axial position and vibration measurement

Installation Guidelines

Ensure the probe is installed with adequate clearance from surrounding structural components to prevent electrical interference. Use the recommended torque settings for the 1/4-28 UNF threading to avoid damaging the probe body. Cables must be routed away from high-voltage AC lines to prevent noise induction. Always verify the gap voltage using a digital multimeter at the Proximitor terminal block during commissioning to ensure the probe is positioned within the specified linear range.

Compliance and Certifications

The 330904-09-17-05-01-05 conforms to hazardous area standards under Option 05, including CSA, ATEX, and IECEx directives for intrinsic safety in explosive atmospheres.
