Description

Engineered for machinery with tight clearance constraints and small target areas, the Bently Nevada 330905-00-07-10-02-CN is a highly specialized 3300 NSv proximity probe designed to monitor shaft vibration and position. This non-contacting sensor is optimized for situations where standard-sized eddy current probes cannot be deployed due to physical spatial envelopes or shaft diameters smaller than 50 mm (2 inches). It forms an integral part of the 3300 NSv Transducer System, converting mechanical displacement into high-precision electrical signals for downstream diagnostic systems.

This specific configuration features an M10 x 1 metric thread design without protective armor, making it ideal for direct internal mounting or clean-run conduit pathways. It incorporates a miniature coaxial ClickLoc connector to ensure robust signal transmission with minimal electrical resistance and high mechanical resilience in demanding industrial environments.

Features

• M10 x 1 metric threaded casing without protective armor for direct-fit installations.
• 0 mm unthreaded case length coupled with a 70 mm overall case length for precise positioning.
• 1.0-meter (39 inches) integrated cable length optimized for proximity sensor coupling.
• Miniature coaxial ClickLoc connector ensures a secure, vibration-resistant connection to extension cabling.
• Designed for small target applications down to 50 mm in shaft diameter.
• Fully compatible with the Bently Nevada 3300 NSv Proximitor Sensor.

Applications

• Centrifugal and axial air compressors.
• Small-scale steam turbines and high-speed turbopumps.
• Hydroelectric and industrial gas turbines with constrained installation envelopes.
• Radial and axial shaft displacement monitoring on high-speed rotating machinery.

Installation Guidelines

• Torque Limits: When mounting the M10 x 1 threaded probe body, do not exceed the recommended installation torque to prevent deformation of the probe tip and internal coils.
• Minimum Bend Radius: Maintain the specified minimum bend radius for standard coaxial cables to prevent impedance mismatch and signal degradation.
• Connector Protection: Ensure the ClickLoc connectors are free of oil, moisture, and dust during assembly. Use silicone connector protectors or heat shrink tubing where environmental contamination is expected.
• System Length Match: Ensure the combined length of the probe and extension cable matches the calibrated length of the corresponding 3300 NSv Proximitor Sensor (typically 5.0m or 7.0m systems).

Compliance and Certifications

• CN Approval Option: Country-specific hazardous area certifications applicable to industrial sites in China.
