The Bently Nevada 330106-00-24-10-02-05, also cataloged as the 3300 XL 8 mm Proximity Probe, operates as a dedicated hardware component for non-contacting vibration and position measurement within rotating machinery monitoring systems.

Configuration and Part Numbering

The specified part number follows the standard Bently Nevada nomenclature structure:

• 330106: 8 mm Proximity Probe, 3/8-24 UNF thread

• 00: Unthreaded length (0 mm)

• 24: Overall case length (240 mm)

• 10: Total length (1.0 meter)

• 02: Connector type (Miniature coaxial ClickLoc connector with connector protector)

• 05: Agency approval option (Multiple approvals)

Technical Data Parameters

Mechanical Monitoring and Eddy-Current Validation

This probe utilizes eddy-current technology to detect the gap between the probe tip and the observed shaft. For optimal signal integrity, the installation must ensure the target material meets required surface finish standards. When connected to a calibrated 3300 XL Proximitor Sensor, the system targets a nominal gap voltage of -10 VDC at the center of the linear range. Maintenance personnel must verify rotor dynamics data against baseline vibration signatures to ensure the probe tip position is correctly established to prevent contact during transient machine conditions.

Package Contents

• 1 x 330106-00-24-10-02-05 8 mm Proximity Probe

• 2 x Hexagonal mounting nuts (3/8-24 UNF)

• 1 x Installation instruction manual

• 1 x Connector protector (pre-installed)

Mechanical Installation Directives

• Clearance: Ensure a radial clearance of at least 40 mm from the probe tip to any metallic obstruction to avoid signal interference.

• Torque: Tighten mounting nuts to a maximum torque of 6.8 N m (60 in-lb) to prevent housing deformation.

• Cabling: Route coaxial cables through dedicated metallic conduits to provide electromagnetic shielding.

• Grounding: Maintain a single-point ground connection at the monitor rack to prevent ground loops in the proximity circuit.

Frequently Asked Questions

• Can this probe be used with 3300 5 mm sensors? No, the 3300 XL 8 mm probe requires a 3300 XL Proximitor Sensor to maintain system linearity.

• What is the maximum cable length? The 1.0 meter integral cable is calibrated specifically for the 3300 XL system; do not extend or shorten without re-calibration.

• Is the tip of the probe replaceable? No, the probe assembly is a sealed, non-repairable unit.

• What is the purpose of the connector protector? It prevents the ingress of moisture and contaminants into the coaxial connector interface.

• Can I use this in hazardous areas? Yes, provided the installation complies with the agency approvals specified on the device label.

• How do I verify probe health? Check the gap voltage at the monitor terminal block; a reading of -10 VDC indicates the probe is positioned at the center of its linear range.

• Are the threads compatible with metric probes? No, this model uses 3/8-24 UNF threads; do not force into metric threaded holes.

• What happens if the cable is cut? Damage to the coaxial cable shield or center conductor will alter the resonant frequency and invalidate the signal output.
