The Bently Nevada 330104-00-08-10-02-00, also cataloged as the 330104 3300 XL 8 mm Proximity Probe, operates as a dedicated hardware component for non-contact vibration and position measurements within rotating machinery monitoring platforms.

Suffix Breakdown & Configuration Matrix

The 330104 model is an 8 mm eddy-current proximity transducer featuring an M10 x 1 threaded case configuration. The specific part number 330104-00-08-10-02-00 breaks down as follows:

• 00: Unthreaded Length (0.0 inches).

• 08: Overall Case Length (0.8 inches).

• 10: Total Length (1.0 meter).

• 02: Connector Option (Miniature coaxial ClickLoc connector, standard cable).

• 00: Agency Approval (No hazardous area approvals).

Hardware Specifications

Machinery Monitoring & TSI Integration

The 330104 probe projects a high-frequency radio frequency field from its 8.0 mm tip to interact with the target shaft. This displacement data is routed to a Proximitor sensor, which generates a voltage signal proportional to the gap distance. For accurate rotor dynamics monitoring, strict gap voltage validation (typically targeting -10 VDC at the monitor) is required. The system utilizes AISI 4140 steel as the calibration target; deviation from this target material requires laboratory recalibration or software offset compensation to maintain the 7.87 V/mm scale factor. Proper installation requires adherence to counterbore clearance boundaries (minimum 31.8 mm) to ensure cross-talk suppression and eliminate side-viewing interference.

Ordering info

• 1 x 330104-00-08-10-02-00 Proximity Probe

• 1 x M10 x 1 stainless steel hex alignment locking nuts

• 1 x Set of silicone connector protective boots

Field Installation Guidelines

• Mechanical Torque:

  Do not exceed 13.5 N·m (120 in-lb) when locking the probe into position. Excessive torque can cause structural separation of the probe tip from the case.

• Cabling:

  Use dedicated, grounded metal conduits to house coaxial cable lines to minimize electromagnetic noise and interference.

• Connector Handling:

  The ClickLoc connectors require finger-tight torque. A "click" sound indicates proper seating; do not overtighten with pliers.

• Environmental Protection:

  Ensure the probe tip remains below 177 deg C for standard applications. For higher temperature environments, utilize ETR (Extended Temperature Range) components.

Frequently Asked Questions

• Can this probe measure both vibration and position?

  Yes, the eddy-current principle allows the system to measure both static shaft position and dynamic vibration signals simultaneously.

• Is this probe interchangeable with older 3300 8 mm components?

  Yes, 3300 XL components are designed to be electrically and physically interchangeable with previous 3300 8 mm transducer systems.

• What happens if the gap voltage is outside the linear range?

  Operation outside the linear range (typically –1 to –17 VDC) will result in signal clipping, inaccurate vibration data, or monitoring system faults.

• Does this probe require matching with its extension cable?

  The 3300 XL system is designed for full component interchangeability. You do not need to bench-calibrate individual components as a system.

• What is the recommended gap setting?

  The standard recommended gap setting is 1.27 mm (50 mils) to maintain the probe within the center of its 2.0 mm linear range.

• Is the connector waterproof?

  The ClickLoc connectors are corrosion-resistant and provide a robust seal, but they are not intended for direct submersion in oil or water without appropriate protective boots.

• Why is the target material important?

  The eddy-current calibration is specific to AISI 4140 steel. Other conductive materials will alter the permeability of the target, shifting the scale factor significantly.

• Can this be installed in a hazardous area?

  This specific part number (ending in -00) does not include hazardous area approvals. Always confirm if your site installation requires Ex-rated (hazardous area) certified equipment.
