 FAQ & Selection Guide

• Q: Can I use this probe in high magnetic fields?
• A: Yes. Output voltage at 60 Hz is only 0.001 to 0.027 V pp per gauss. Good for motors and generators.
• Q: What if my target is larger than 11 mm?
• A: The 11 mm probe works with flat targets ≥15 mm diameter for best linearity.
• Q: How to choose total probe length?
• A: Select 1 m for short runs, 5 m for medium, or 9 m for long distances to the monitor.
• Practical tip from field engineers:
• When installing, use the recommended 21.1 N•m torque. Over-tightening may crack the probe tip.
• Selection guide:
• For standard duty, choose option 00 (no armor). For abrasive or high-vibration areas, take the armored version.
• Pick option 02 connector for quick locking. Use standard cable for indoor use.
• If ambient exceeds 120°C, check temperature class T3 or higher. For 177°C, use T2.
