Configured for high-sensitivity shaft displacement monitoring in 3300 NSv systems, the Bently Nevada 330908-00-16-10-01-05 (330908-00-16-10-01-05 Proximity Probe) provides direct physical/electrical execution for tracking radial and axial motion on small-diameter rotors.

Suffix Model Matrix

The 330908 series uses a modular coding system to define mechanical and electrical properties. The suffix -00-16-10-01-05 indicates specific thread dimensions, case length, integral cable length, and connector termination standard required for integration into 3300 NSv transducer systems.

Hardware Specifications

Transducer System Signal Integrity

The 3300 NSv transducer system is designed to provide high-resolution displacement data for small-target applications. Accurate rotor dynamics analysis depends on precise eddy-current probe scaling to ensure linear voltage output. Commissioning requires gap voltage validation (-10 VDC targets) at the Proximitor output to confirm the target is within the linear operating range. To prevent measurement errors, cross-talk suppression is achieved by maintaining coaxial shield integrity and grounding the cable shield at the monitoring end only, which prevents ground loop currents from introducing electromagnetic interference.

Field Installation Guidelines

• Surface Conditioning: Ensure the shaft target area is free of mechanical defects, coatings, or oxidation to maintain eddy-current field uniformity.

• Mechanical Mounting: Thread the probe body into the mounting bracket; verify the gap distance meets machine-specific requirements after securing locking nuts.

• Cable Management: Route the coaxial cable through grounded conduits away from high-power AC cabling; avoid tight bends that exceed the 50 mm minimum radius.

• Connector Handling: Protect the coaxial connector interface from moisture and dust using provided caps until final connection.

• Shielding: Confirm the shield is connected only at the Proximitor end to preserve signal noise floor specifications.

Frequently Asked Questions

• Can this probe be used in 3300 XL systems? No, the 3300 NSv probe has different impedance characteristics and requires the 3300 NSv Proximitor.

• Is the cable length field-adjustable? No, cable length is factory-calibrated for specific capacitance; alteration renders the sensor inaccurate.

• How is signal linearity verified? Linearity is verified by performing a static calibration check to ensure the output matches the 200 mV/mil sensitivity.

• What signifies a failed probe tip? Structural damage to the PPS tip creates field irregularities; replace the unit if the tip is cracked.

• Can I use this in vacuum conditions? Yes, the assembly is compatible with vacuum environments provided the connector is protected.

• What causes 50/60 Hz noise on the output? This is typically caused by a ground loop or a breach in the coaxial shield.

• Is the housing material corrosion-resistant? Yes, the AISI 303 stainless steel housing is designed for industrial machine environments.

• Does probe orientation matter? For radial measurements, mount the probe 45 degrees from the vertical centerline for bearing analysis.
