Hardware Specifications

Eddy‑Current Probe Scaling and Gap‑Voltage Validation

The 3300 XL 8 mm probe maintains a calibrated −10 VDC gap‑voltage target to ensure linear displacement scaling across proximitor interfaces. The short 0.5 m cable minimizes impedance variation, improving phase stability for rotor‑dynamic analysis. ClickLoc termination provides repeatable electrical seating, suppressing cross‑talk in multi‑probe installations. The probe’s eddy‑current field geometry supports stable sensitivity when mounted near high‑speed rotating machinery.

Frequently Asked Questions

Q: Can the probe be removed while the proximitor remains energized? A: Removal should occur only with the channel de‑energized to avoid transient gap‑voltage excursions.

Q: Does the 0.5 m cable length require proximitor recalibration? A: No. The cable length is factory‑matched to standard 3300 XL proximitor modules.

Q: Does the “00” approval suffix affect electrical performance? A: No. It indicates no hazardous‑location certification; electrical characteristics remain unchanged.

Field Installation Guidelines

• Maintain clean mounting surfaces to ensure stable eddy‑current field alignment.
• Terminate cable shielding at the proximitor end only to prevent ground‑loop formation.
• Avoid sharp bends in the cable to preserve coaxial impedance.
• Route probe wiring away from high‑current conductors to reduce electromagnetic interference.
• Verify ClickLoc connector engagement before energizing the monitoring channel.
