Frequently Asked Questions (FAQ)

• Q: What is the linear measurement range of this probe?
  A: The 3300 XL 8mm Probe provides 2 mm (80 mils) linear range from 0.25 mm to 2.3 mm (10 to 90 mils).
• Q: Can I extend the cable beyond 1.0 meter?
  A: Yes, you can use field wiring up to 305 meters (1000 ft) between the proximitor sensor and monitor, but the probe assembly itself has a fixed 1.0 m cable.
• Q: Does the probe require any external barrier for hazardous locations?
  A: For intrinsic safety (Zone 0), install with approved zener barriers or galvanic isolators per drawing 141092.
• Q: What is the recommended target material?
  A: Use ferrous metals (e.g., 4140 steel) for optimal linearity and scale factor stability.
• Q: Is the probe pressure tested before shipment?
  A: Bently Nevada does not pressure test standard probes. Contact custom design department if your application requires pressure seal verification.
