Bently Nevada 330903-00-09-05-02-05 3300 XL NSv Proximity Probe

Description

330903-00-09-05-02-05: 3300 XL NSv proximity probe, M8x1 thread, Option 00 (0.0 in unthreaded length), Option 09 (0.9 in case length), Option 05 (0.5 m total length), Option 02 (standard cable, no armor), and Option 05 (multiple agency approvals). This non-contact eddy-current displacement probe is designed for the 3300 XL NSv proximity transducer system, specifically for measuring shaft vibration and axial position on small-bore machinery, high-speed equipment, and aeroderivative turbines where target geometry is limited. The NSv system provides a shorter linear range (1.5 mm / 60 mils) compared to standard 3300 XL probes, allowing for improved side-view characteristics essential for tight clearance applications. This configuration includes a 0.5 meter probe lead and is compatible with 3300 XL NSv Proximitor sensors and extension cables to maintain the necessary 5.0 meter or 7.0 meter system length requirements.

Features

• M8x1 probe thread (330903 series, unarmored)
• 0.0 in unthreaded length (Option 00)
• 0.9 in overall case length (Option 09)
• 0.5 m total system lead length (Option 05)
• Miniature coaxial ClickLoc connector, standard cable (Option 02)
• Multiple agency approvals for hazardous area installations (Option 05)
• 1.5 mm (60 mils) linear range for high-accuracy small-target measurement

Applications

• Small-bore machinery shaft vibration monitoring
• Axial position measurement on aeroderivative gas turbines
• High-speed rotating equipment with limited target area
• Critical machinery protection systems requiring tight clearance sensing

Installation Guidelines

Ensure the probe gap is set to approximately 1.0 mm (40 mils) during installation to center the signal within the linear range. The 330903 probe is designed for standard mounting; ensure the probe body is properly isolated if required by the installation drawing. When connecting, utilize the ClickLoc miniature coaxial connectors and verify that all connections are secure and protected using provided connector protectors if applicable. The total system length (Probe + Extension Cable) must match the calibration of the 3300 XL NSv Proximitor Sensor.
