Bently Nevada 330106-05-30-50-12-00 3300 XL 8 mm Reverse Mount Proximity Probe

The Bently Nevada 330106-05-30-50-12-00, also cataloged as the 330106 8 mm Reverse Mount Proximity Probe, operates as a dedicated hardware component for non-contact shaft displacement measurement within the 3300 XL 8 mm Proximity Transducer System. The probe uses M10 x 1 metric threads and connects through a matched Proximitor Sensor and extension cable to convert target position changes into proportional electrical signals.

Eddy-Current Probe Scaling and Gap Voltage Validation

The Bently Nevada 330106-05-30-50-12-00 uses an eddy-current measurement principle to detect changes between the probe tip and a conductive target. The matched 3300 XL Proximitor Sensor converts these gap changes into a proportional voltage signal.

The specified incremental scale factor is 7.87 V/mm or 200 mV/mil. Therefore, the complete probe, extension cable, and Proximitor Sensor must operate as a matched system to maintain the specified calibration characteristics.

During installation, technicians should verify the mechanical probe gap and corresponding system output before placing the measurement channel into service. Gap voltage validation is commonly used to confirm that the probe operates within its calibrated measurement range. However, the exact target voltage depends on the configured system, target material, and mechanical application.

The probe also supports machinery measurements associated with rotor dynamics, including radial shaft vibration and axial position monitoring when installed with the appropriate monitoring hardware.

Frequently Asked Questions

Q: Can the Bently Nevada 330106-05-30-50-12-00 operate as a standalone sensor?
A: No. The probe is part of the 3300 XL Proximity Transducer System and requires compatible extension cable and Proximitor Sensor components for normal signal conditioning and measurement.

Q: What target material should be used for calibration and specified performance?
A: The provided specification references standard AISI 4140 steel. Target material, geometry, and surface condition can affect probe system response and calibration.

Q: What is the function of the FluidLoc cable option?
A: The FluidLoc cable configuration is designed to block internal fluid migration through the cable assembly.

Field Installation Guidelines

Install the Bently Nevada 330106-05-30-50-12-00 in a mechanically stable mounting location and ensure correct engagement of the M10 x 1 probe thread. Maintain the specified clearance between the probe tip and the conductive target during installation.

Use the matched 3300 XL extension cable and Proximitor Sensor configuration for the specified system length. Do not substitute cable assemblies with different electrical characteristics unless the complete measurement system has been recalibrated.

Route probe cables separately from high-current power conductors and switching circuits where practical. In addition, protect the cable from sharp bends, mechanical stress, and excessive vibration.

Maintain connector cleanliness and secure the ClickLoc connection using the specified locking arrangement. Do not apply excessive torque to the connector.

After mechanical installation, verify the probe gap and system output against the applicable monitoring system configuration. Finally, confirm that the signal remains stable before commissioning the machinery protection or condition monitoring channel.
