Description

The Bently Nevada 330106-05-30-05-02-00, also cataloged as the 330106 Proximity Probe, operates as a dedicated hardware component for non-contacting vibration and position measurements within 3300 XL Proximity Transducer System platforms.

Hardware Specifications

Mechanical Monitoring and TSI Verification

The Bently Nevada 330106-05-30-05-02-00 functions alongside a 3300 XL Proximitor Sensor to convert mechanical displacement into an electrical signal. During installation and testing, personnel must execute gap voltage validation to confirm that the static probe position matches the linear range of the sensor. The target calibration requires a -10 VDC gap voltage output, which corresponds to the midpoint of the linear RF signal modulation. Furthermore, the internal construction of the probe tip employs advanced cross-talk suppression techniques, which effectively eliminates magnetic interference when mounting adjacent eddy-current probes on the same rotor dynamics observation plane.

Frequently Asked Questions

Q: What is the significance of the “02” connector option on this probe?

A: The “02” designation indicates that the probe comes with a miniature coaxial ClickLoc connector and a pre-installed connector protector. This prevents fluid contamination and mechanical unlocking at the junction between the probe lead and the extension cable.

Q: Can this probe operate properly without a 3300 XL Proximitor Sensor?

A: No. The probe acts as a purely passive inductive element. It requires the high-frequency RF excitation signal from a compatible 3300 XL Proximitor Sensor to establish the eddy-current field and evaluate target position.

Field Installation Guidelines

• Thread Engagement and Torque: Thread the probe into the bracket by hand until the tip approaches the target material. Always ensure a minimum of 5 full threads of engagement to maintain physical mounting stability under high-vibration conditions.
• Gap Adjustment: Connect a digital multimeter to the Proximitor Sensor output terminals. Rotate the probe until the gap voltage reads exactly -10 VDC, which indicates the center of the calibrated 80 mil linear range.
• Cable Routing and Shielding: Route the 0.5 m integral probe cable away from high-voltage conduit lines. You must ground the extension cable shield at the Proximitor housing while keeping the probe tip isolated from the machine casing to avoid ground loops.
