Frequently Asked Questions (FAQ)

• Q: What is the difference between standard and optional FluidLoc cable?
  FluidLoc prevents oil or process liquid migration through the probe cable interior, ideal for machines with potential leaks.
• Q: Can I use this 3300 XL 8 mm Probe with 9-meter extension cables?
  Yes, the system maintains 7.87 V/mm scale factor with ±6.5% interchangeability when using extended lengths.
• Q: What shipping carriers do you use?
  We ship worldwide via FedEx, UPS, and DHL to ensure fast and tracked delivery.
• Q: Is this probe compatible with previous 3300 series monitors?
  Yes, the 3300 XL 8 mm Probe works with 3300 XL proximitor sensors and most 3300 monitoring systems.
• Q: What approvals does suffix 05 include?
  Option 05 includes CSA, ATEX, and IECEx certifications for hazardous area installations.
• Q: How do I set the gap for radial vibration?
  Adjust probe target gap to obtain -9 Vdc output, which equals approx 1.27 mm (50 mils) air gap.
