Hardware Specifications

Performance Characteristics

The 3300 XL 8 mm probe maintains the standard –10 VDC nominal gap‑voltage target, ensuring linear displacement scaling across the proximitor’s calibrated range. The long 5.0 m cable is factory‑matched to preserve coaxial impedance, maintaining phase stability and minimizing distortion during high‑speed rotor‑dynamic analysis. The armored construction provides mechanical protection in harsh industrial environments, while the ClickLoc™ connector ensures secure, repeatable electrical engagement.

Frequently Asked Questions

Q: Does the 5.0 m cable length require proximitor recalibration A: No. The cable length is factory‑matched to standard 3300 XL proximitor sensors.

Q: Does the “02” approval suffix affect electrical performance A: No. It simply indicates standard (non‑hazardous) certification; electrical characteristics remain unchanged.

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

Field Installation Guidelines

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