Frequently Asked Questions (FAQ)

• Q: Can I use this 3300 XL 8 mm probe with a 9-meter extension system?
  A: Yes, the probe works with standard extension cables; scale factor tolerance becomes ±6.5% for 9-meter total systems.
• Q: Does the probe resist oil or chemical ingress?
  A: The standard Viton O-ring provides pressure sealing. Order the FluidLoc cable option for additional liquid protection.
• Q: What is the maximum probe temperature for continuous operation?
  A: Standard probe withstands +177°C (+350°F); extended temperature probe tip supports up to +218°C (+425°F).
• Q: Is the 330101-10-27-05-02-00 compatible with existing 3300 XL proximity systems?
  A: Absolutely. This model matches 3300 XL 8 mm Proximity Proximitor sensors and 3300 monitoring systems seamlessly.
• Q: How do I verify the probe DC resistance?
  A: Use a multimeter across center and outer conductor; nominal RPROBE for 0.5 m length equals 7.45 ±0.50 Ω.
