Eddy-Current Scaling and Gap Voltage Validation Behavior

The 3300 XL probe structure implements eddy-current field interaction with conductive shaft targets, producing a demodulated voltage proportional to probe-to-target spacing. Signal conditioning is dependent on proximitor excitation carrier stability and calibrated -10 VDC to 0 VDC gap voltage mapping. Cross-channel interference suppression is achieved through coaxial shielding integrity and ClickLoc connector impedance stability, ensuring minimal signal distortion in multi-probe installations within rotating machinery assemblies.

Frequently Asked Questions

Q: Can the 330100-50-02 operate without a 3300 XL Proximitor Sensor?
A: No. The probe is a passive transducer and requires an external proximitor module to generate excitation and convert eddy-current impedance variation into voltage output.

Q: Is the probe compatible with mixed cable lengths in a single loop?
A: Only system-defined extension cables matched to the 3300 XL calibration constant are permitted. Mismatched total loop length affects scale factor linearity.

Q: What is the limitation of signal integrity in high EMI environments?
A: Performance depends on coaxial shielding continuity and proper grounding. Improper shield termination increases cross-talk and noise coupling.

Field Installation Guidelines

• Maintain consistent 90 deg routing bends with minimum coaxial cable stress radius compliance
• Ensure probe tip alignment perpendicular to target shaft surface to preserve eddy-current linearity
• Ground cable shield at single-point system reference only to avoid ground loop current
• Verify probe gap calibration using static shaft reference before dynamic commissioning
• Avoid mechanical preload on probe tip during installation torqueing sequence
