Description

Engineered for critical machinery protection and turbomachinery condition monitoring, the Bently Nevada 330901-00-64-10-02-CN is a high-precision sensor belonging to the 3300 NSv Proximity Transducer system. Designed primarily for areas with tight clearance constraints or small target geometries where standard-size proximity probes cannot be physically deployed, this eddy current sensor provides stable, non-contact measurements of dynamic shaft vibration and static position.

The 330901-00-64-10-02-CN variant features a fully-customized physical footprint, featuring a 6.4-inch overall case length with no unthreaded section (0.0 inches), allowing for precise depth adjustment in compact mechanical housings. Signal transmission integrity is maintained via a 1.0-meter integrated cable terminating in a miniature coaxial ClickLoc connector, ensuring robust electrical coupling with the system extension cable even in environments subject to continuous vibration and high humidity.

Features

• Optimized for small-diameter targets and tight mechanical installations where standard 5mm or 8mm proximity probes are unsuitable.
• Non-contact design prevents mechanical wear and physical degradation during continuous operation.
• Robust miniature coaxial ClickLoc connector prevents accidental disconnection and maintains low signal impedance.
• Excellent thermal stability and chemical resistance for reliable deployment inside gas turbines, steam turbines, and industrial gearboxes.
• Country-specific (CN) approval compliance for standardized industrial installations.

Applications

• Radial shaft vibration and axial position measurement on high-speed pumps and compressors.
• Thrust and radial displacement monitoring on small-diameter steam or gas turbine rotors.
• Machinery protection systems (TSI) in power generation, oil & gas, and petrochemical refining.
• Hydroelectric generator shaft alignment and vibration telemetry.

Installation Guidelines

• Thread Clearance: Ensure the mounting hole is tapped correctly for a 3/8-24 UNF thread. Since the probe has a 0.0-inch unthreaded length, verify that the case threads can fully engage without binding.
• Cable Routing: Observe the minimum bend radius constraints for coaxial cables to prevent internal conductor damage. Secure the cable along its route using non-conductive, vibration-resistant ties.
• Connector Protection: Verify that the ClickLoc connector is dry and clean before mating. Use silicone connector protectors or heat-shrink tubing if moisture exposure is expected.
• Target Alignment: Align the probe tip perpendicular to the observed shaft target surface. Side-clearance must be kept clear of metallic obstructions to prevent side-loading calibration errors.
