Bently Nevada 330103-00-06-05-02-02 3300 XL 8 mm Proximity Probes

Configured for specific technical tasks in TSI systems, the Bently Nevada 330103-00-06-05-02-02 (330103 Proximity Sensors) provides direct physical/electrical execution. This component measures dynamic distance changes between the probe tip and the observed rotating shaft target. The hardware operates within the 3300 XL Proximity Transducer System to output continuous analog voltage signals proportional to the static and dynamic gaps.

Hardware Specifications

Machinery Monitoring & TSI Characteristics

The hardware establishes proximity measurement via an eddy-current probe scaling methodology. The Proximitor Sensor generates a high-frequency RF signal through the extension cable to the probe tip, inducing eddy currents in the target material. The field strength changes according to the physical gap distance. The system validates the nominal gap voltage around a -10 VDC target midpoint within the linear range, ensuring stable operations for rotor dynamics analysis. To maintain signal integrity across long distances, the design integrates cross-talk suppression mechanics, which isolate the RF frequencies from adjacent proximity probe channels and minimize measurement noise.

Frequently Asked Questions

Q: What physical constraints dictate the installation of the unarmored cable option?

A: The unarmored cable requires routing through rigid or flexible conduit systems to prevent mechanical damage, abrasion, and exposure to sharp environmental hazards inside the machine housing.

Q: How does the ClickLoc connector maintain electrical continuity under heavy machinery vibration?

A: The ClickLoc coaxial connector utilizes a positive-locking mechanism that physically detents into position, maintaining tight physical contact between the gold-plated surfaces and preventing impedance changes or accidental disengagement.

Q: Can this probe operate independently without an external power source?

A: No, the probe functions as a passive inductive-capacitive element. It requires an active excitation voltage from a matching 3300 XL Proximitor Sensor to generate the necessary radio frequency field.

Field Installation Guidelines

• Maintain the factory-specified minimum bend radius of 25.4 mm (1.0 inch) for the coaxial cable during routing to prevent internal insulation degradation or changes in characteristic impedance.
• Isolate all probe wiring from high-voltage AC lines and transient switching circuits to minimize electromagnetic interference across the measuring loop.
• Verify target material composition prior to final calibration, as the standard eddy-current probe scaling assumes an AISI 4140 steel target surface.
• Thread the probe into the mounting bracket using manual torque before applying tools, ensuring the M10 x 1 threads engage smoothly without cross-threading.
