Bently Nevada 330104-00-22-10-02-00 3300 XL 8 mm Proximity Probe

The Bently Nevada 330104-00-22-10-02-00, also cataloged as the 330104 Proximity Probe, operates as a dedicated hardware component for non-contact displacement measurements within 3300 XL Proximity Transducer System platforms. The probe measures static position and dynamic vibration inputs on fluid-film bearing machinery, generating raw eddy-current signals proportional to the gap distance between the target surface and the probe tip.

Hardware Specifications

Eddy-Current Probe Scaling and Rotor Dynamics Calibration

The 330104-00-22-10-02-00 features a precision-wound tip coil engineered to establish strict eddy-current probe scaling parameters. During field installation, engineering teams perform gap voltage validation, adjusting mechanical positioning until achieving target baseline voltages (typically a -10 VDC target zone) to align the sensor within its linear operational range. This design preserves measurement integrity across high-speed rotor dynamics evaluations, while integrated coaxial shielding properties enforce cross-talk suppression when routing multiple signal lines through shared industrial conduits or terminal boxes.

Frequently Asked Questions

Q: Can this 1.0-meter probe be wired directly to an analog input card without a Proximitor Sensor?

A: No. The probe requires a calibrated extension cable and a matching Proximitor Sensor to convert the high-frequency eddy-current impedance variations into a stable, usable voltage signal.

Q: What action should be taken regarding the electrostatic discharge note in the documentation?

A: Technicians must apply standard ESD precautions, including wearing grounded wrist straps during handling, to prevent static damage to the internal coil and the sensitive terminal circuits of the connected Proximitor.

Field Installation Guidelines

• Mechanical Seating and Torque: Hand-thread the 220 mm fully threaded case assembly into the mounting bracket or sleeve to prevent cross-threading. Tighten using specified engineering torque tolerances to protect the internal tip mechanics from compression failure.

• ClickLoc Connector Interface: Ensure the miniature coaxial ClickLoc connection is clear of dirt or moisture before mating. Push the sleeves together firmly until the mechanical detent engages, providing a low-resistance electrical path.

• Side-View Clearance Envelope: Maintain proper radial clearance boundaries around the 8 mm probe head. Proximity to unauthorized structural casing metal creates a parasitic signal loop that distorts the calibration scale factor.
