Hardware Specifications

Eddy-Current Probe Scaling and Rotor Dynamics

The probe operates via eddy-current proximity probe scaling to generate an output voltage directly proportional to the physical gap between the 8 mm tip and the target conductive surface. To preserve accurate rotor dynamics measurements, the matching Proximitor sensor establishes a target gap voltage validation near -10 VDC to bias the system within its linear measurement window. The internal composition supports complete component interchangeability across matching lengths without manual bench calibration. The specialized coaxial shielding prevents external EMI from degrading dynamic vibration or static position information, while physical construction provides cross-talk suppression between adjacent probe tips.

Frequently Asked Questions

Q: Does this 9.0-meter probe require calibration to its specific extension cable and Proximitor sensor?

A: No. The 3300 XL 8 mm system components allow complete interchangeability, eliminating the need to match or bench calibrate individual components or custom-tune the hardware.

Q: Is this probe backward compatible with older non-XL components?

A: Yes, each component of the 3300 XL 8 mm system is backward compatible and interchangeable with non-XL 3300 series 5 mm and 8 mm transducer system elements.

Field Installation Guidelines

• Thread Engagement and Gap Setup: Mechanical installation must verify mechanical clearance before gapping. Adjust the probe depth while tracking the gap voltage with a digital voltmeter to verify the target voltage baseline.
• Coaxial Connector Isolation: Ensure the miniature coaxial ClickLoc connectors are clean and dry during assembly. Wrap all intermediate connections with self-fusing silicone tape to prevent moisture ingress and grounding paths against the machine casing.
• Conduit Routing and Bend Radius: Route the 9.0-meter integrated probe lead through dedicated flexible or rigid conduit. Maintain the minimum recommended bend radius for coaxial cables to prevent internal conductor damage or signal distortion.
