Professional FAQ & Selection Guide

• Is this probe compatible with modern 3300 XL systems?
• No. The 7200 series is electrically distinct. Always match your probe series to your Proximitor series to avoid calibration errors.
• What is the benefit of a fully threaded (00 option) probe?
• It allows for deeper reach and more precise mechanical gapping in internal machine mounts compared to partially threaded versions.
• What happens if the lead length is altered?
• Never cut or splice the lead; it is factory-tuned. Altering the length will destroy the linearity and scale factor accuracy.
• Can it withstand acidic environments?
• Yes, the 8mm probe is rated for contact with 10% sulfuric acid and various solvents like MEK.
• How do I confirm the probe is functional before install?
• Measure the continuity and resistance between the center pin and outer shell; an open circuit indicates a broken internal coil.
