Bently Nevada 330909-00-99-10-02-00 3300 NSv Proximity Probes

The Bently Nevada 330909-00-99-10-02-00, also cataloged as the 330909 3300 NSv Proximity Probe, operates as a dedicated hardware component for displacement and vibration sensing within Bently Nevada 3300 XL NSv Proximity Transducer systems.

Hardware Specifications

Eddy-Current Probe Scaling & Rotor Dynamics

The 3300 NSv probe utilizes eddy-current scaling optimized for specialized rotor dynamics, providing an Average Scale Factor of 7.87 V/mm (200 mV/mil) over a 1.5 mm (60 mils) linear range. Due to enhanced side-view characteristics designed to circumvent tight counter bore constraints, physical cross-talk suppression is high. This configuration allows accurate static and dynamic measurements on small targets. Field commissioning demands rigorous gap voltage validation, targeting standard -10 VDC targets at the center-scale position to establish a reliable baseline on fluid-filmed bearing machines.

Frequently Asked Questions

Q: How does the linear range of this NSv probe compare to legacy Bently Nevada 3000-series 190 systems?

A: This NSv probe delivers a 1.5 mm (60 mils) linear range, which exceeds the total linear tracking measurement range of the legacy 3000-series 190 Transducer System.

Q: Can this probe be integrated directly into an existing legacy 3300 RAM system installation?

A: Yes. When upgrading from a 3300 RAM system, the existing probe and extension cable can be retained, provided they are interfaced to a compatible 3300 XL NSv Proximitor Sensor.

Field Installation Guidelines

• Target Alignment on Small Shafts: When monitoring radial vibration on shafts under 51 mm (2 in), ensure the probe tip is perpendicular and centered perfectly to prevent measurement errors caused by shaft curvature.

• Coaxial Connection Isolation: Install non-conductive insulation sleeves over the miniature coaxial ClickLoc connector to isolate the loop from structural grounding.

• Mechanical Thread Engagement: Hand-thread the probe into the mounting bracket to avoid cross-threading, locking it firmly into position once the gap voltage validation registers the designated static offset.
