Frequently Asked Questions (FAQ)

Q1: Is the Bently Nevada 330709-000-080-50-12-05 probe brand new and original?
Yes. We supply 100% genuine new original Bently Nevada 3300 XL series probes. No refurbished or counterfeit units.

Q2: Does this 5-meter probe work with any 3300 XL Proximitor Sensor?
Bently Nevada designed 330709-000-080-50-12-05 specifically for the 5-meter Proximitor Sensor only. Using a different cable length will cause linearity errors. Always match the 5.0 meter total length with the correct proximitor.

Q3: What is the linear measurement range for this 11 mm probe?
The 3300 XL 11 mm probe provides a linear range from 0.25 mm to 2.5 mm (10 to 100 mils) for ferrous targets. Performance depends on target material and shaft diameter.

Q4: What does agency approval option 05 (Multiple Approvals) mean?
Option 05 certifies the probe for hazardous area installations. It complies with ATEX, IECEx, and Class I Div 1 requirements. Refer to the temperature classification table for safe operating limits.

Q5: What torque should I apply to the M16x1.5 probe case?
Use recommended torque 21.1 N·m (187 in·lb). Maximum allowable torque is 63.3 N·m. Over-torquing may damage threads or the internal sensing coil.

Q6: Do you have stock? How quickly can you ship?
Yes, we have 330709-000-080-50-12-05 in stock ready to ship. We dispatch within 5 days via FedEx, UPS, or DHL. Express delivery typically takes 3–7 business days worldwide.

Q7: What is the return policy for this probe?
We offer 30-day returns from the delivery date. The item must remain unused in original packaging. Customer pays return shipping unless the product is defective.

Q8: What is the minimum recommended shaft diameter for accurate measurements?
Bently Nevada specifies a minimum shaft diameter of 152 mm (6.0 inches) for the 11 mm probe. This avoids electrical runout and cross-talk issues.

Q9: Can I use this probe below -34°C?
Bently Nevada warns that exposing the probe below -34°C (-30°F) may cause premature pressure seal failure. Stay within the rated operating range for reliability.
