Temperature Range & Environmental Tolerance

• Operating and storage temperature: -52°C to +177°C (-62°F to +351°F).
• Important note: Exposing the probe below -34°C (-30°F) may cause premature pressure seal failure.
• Temperature classification (EPL Ga/Gc):
  • T1: -55°C to +232°C  |  T2: -55°C to +177°C
  • T3: -55°C to +120°C  |  T4: -55°C to +80°C  |  T5: -55°C to +40°C
• Temperature classification (EPL Dc): T280°C / T225°C / T170°C / T130°C / T105°C / T90°C with ambient limits from -55°C up to +232°C (depending on class).
• Probe withstands high thermal stress – ideal for turbines, compressors, and generators.

Frequently Asked Questions (FAQ)

Q1: Is the Bently Nevada 330709-000-080-50-11-05 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 this 330709-000-080-50-11-05 specifically for the 5-meter Proximitor Sensor. Using a different cable length may cause linearity errors. Always match total length 5.0 m with the correct proximitor.

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

Q4: Can I install this probe in a hazardous area?
Yes. Agency approval option 05 = Multiple Approvals complies with ATEX, IECEx, and Class I Div 1 requirements. Refer to temperature classification table for safe area use.

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 coil.

Q6: Do you have stock? How quickly can you ship?
Yes, we have 330709-000-080-50-11-05 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 delivery date. The item must remain unused, in original packaging. Customer covers return shipping unless defective.

Q8: 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 to avoid electrical runout and crosstalk issues.
