Configured for shaft displacement measurements in 3300 NSv monitoring systems, the Bently Nevada 330910-16-23-10-02-00 (330910 Proximity Probe) provides direct physical/electrical execution for non-contact vibration monitoring.

Model Suffix Breakdown

The 330910 transducer is designed for near-field applications. Part number configuration includes:

• 16: Unthreaded length (1.6 inches).

• 23: Overall case length (2.3 inches).

• 10: Total cable length (1.0 meter).

• 02: Connector option (Miniature coaxial ClickLoc).

• 00: Agency approval (None).

Hardware Specifications

Mechanical Monitoring & TSI Technical Attributes

The 3300 NSv system utilizes specific eddy-current probe scaling optimized for small-diameter shafts or constrained installation environments. Maintaining signal integrity requires rigorous gap voltage validation at the nominal -10 VDC setpoint to ensure linear transducer response. Rotor dynamics analysis depends on this calibration accuracy. During integration, cross-talk suppression must be addressed by ensuring sufficient physical distance from neighboring sensors, minimizing electromagnetic interference and ensuring accurate peak-to-peak vibration data capture.

Field Installation Guidelines

• Mechanical Torque:

  Secure mounting nuts to a maximum of 13.5 N·m (120 in-lb). Excessive force damages probe housing threads.

• Coaxial Routing:

  Run signal cabling through dedicated, grounded rigid metal conduit. Shielding is mandatory to prevent capacitive coupling and EMI from neighboring power lines.

• Connector Seating:

  The ClickLoc interface must be seated until a distinct click is audible. Do not utilize mechanical pliers, as this deforms contact pins.

• Thermal Management:

  The installation site must not exceed the +177 deg C limit. Excessive heat degrades internal coil insulation and causes output signal drift.

Frequently Asked Questions

• Is this probe compatible with standard 3300 XL Proximitor sensors?

  No. The 330910 NSv probe is specifically designed for the 3300 NSv Proximitor and is not electrically interchangeable with XL system components.

• How is the probe gap set for this model?

  The gap is adjusted by measuring the DC output voltage relative to the probe face, ensuring it resides in the center of the 1.5 mm linear range.

• Can I shorten the 1.0 meter cable?

  No. The cable length is calibrated to the Proximitor impedance. Modification will result in signal attenuation and inaccurate rotor dynamics data.

• Does this probe require a specific target material?

  Calibration is factory-optimized for AISI 4140 steel. Alternative target metals change magnetic permeability and require sensitivity recalibration.

• Is the connector waterproof?

  The ClickLoc connector is designed for industrial use. Use the provided silicone boot to ensure a proper seal against environmental moisture and oil.

• Why is the linear range smaller than the 3300 XL probe?

  The 3300 NSv series is engineered for near-field, small-gap measurement, necessitating a compressed linear range to maintain sensitivity on smaller targets.

• Can I perform an online probe replacement?

  Yes, provided the monitoring system channel is in a "Bypass" or "Maintenance" mode to prevent the triggering of machine protection logic.

• What signifies a damaged probe tip?

  Signal clipping, extreme gap voltage fluctuations, or inability to achieve a stable DC output indicate physical damage to the internal coil or shield.
