Bently Nevada 330903-00-06-05-02-05 3300 XL NSv Proximity Probe

Description

330903-00-06-05-02-05: 3300 XL NSv proximity probe with M8x1 thread, featuring Option 00 (0.0 in unthreaded length), Option 06 (60 mm case length), and Option 05 (0.5 m total length). This non-contact, eddy-current transducer is engineered for high-precision displacement and vibration measurement in applications with limited target clearance or smaller target geometry.

This configuration utilizes Option 02 (standard miniature coaxial ClickLoc connector) and Option 05 (CSA, ATEX, and IECEx multiple hazardous area approvals). As a core element of the 3300 XL NSv proximity transducer system, this probe maintains a consistent scale factor for accurate shaft position and vibration monitoring in demanding industrial environments, including aeroderivative turbines and small-bore rotating machinery.

Features

• Option 00 (Unthreaded Length): 0.0 in length, fully threaded probe body
• Option 06 (Case Length): 60 mm total case length for specific mounting depth requirements
• Option 05 (Total Length): 0.5 m total probe lead length
• Option 02 (Connector/Cable): Miniature coaxial ClickLoc connector with standard cable; non-armored design
• Option 05 (Agency Approval): Multiple hazardous area certifications (CSA, ATEX, IECEx)
• Probe Thread: M8x1 thread, AISI 304 stainless steel case
• Compatibility: Designed for use with 3300 XL NSv Proximitor sensors and 3300 NSv extension cables

Applications

• Radial vibration and axial position measurements
• Small-bore machinery (target diameter less than 20 mm / 0.8 in)
• Aeroderivative gas turbines
• High-speed equipment where standard 8 mm probes lack linear range or clearance
• Critical machinery monitoring in hazardous locations

Technical Specifications

Installation Guidelines

• Ensure the probe is installed with the appropriate gap as specified by the machine monitoring configuration.
• Use 3300 XL NSv compatible extension cables; ensure total system length matches the Proximitor sensor calibration.
• Connectors should be protected from environmental contaminants; use of silicone self-fusing tape or connector protectors is recommended for long-term reliability.
• Ensure the mounting location is properly isolated from the housing ground to prevent ground loops.
• Install per Bently Nevada drawings 141092 (intrinsically safe) or 140979 (non-incendive) depending on the hazardous area classification.
