Technical Parameters – Bently Nevada 330709-000-080-50-12-00

• Probe DC resistance (R_PROBE): 7.2 ± 0.8 ohms from center to outer conductor at 5.0 meters.
• Target size – flat surface: Recommended minimum diameter 30.5 mm (1.2 in).
• Shaft diameter: Recommended minimum 152 mm (6.0 in) for proper linearity.
• Probe tip material: Polyphenylene sulfide (PPS) – excellent chemical and wear resistance.
• Probe case material: AISI 304 stainless steel (SST) for corrosion resistance.
• Cable specification: 75 Ω triaxial, FEP insulated cable (5.0 meters total).
• Minimum bend radius (with or without armor): 25.4 mm (1.0 in) – protect cable integrity.
• Maximum thread engagement length: 24 mm for M16x1.5 probe case.

Temperature Range & Environmental Limits

• Operating and storage temperature: -52°C to +177°C (-62°F to +351°F).
• Critical note: Exposing the probe below -34°C (-30°F) may cause premature pressure seal failure.
• The probe withstands high thermal stress for turbines, generators, and compressors.
• AISI 304 stainless steel case provides durability in corrosive or wet environments.

Torque & Mechanical Installation Guidelines

• Maximum rated torque for M16x1.5 probe case: 63.3 N•m (560 in•lb) – never exceed this value.
• Recommended mounting torque: 21.1 N•m (187 in•lb) ensures proper sealing without damage.
• Connector-to-connector torque: Finger tight recommended. Maximum torque 0.565 N•m (5 in•lb).
• Clean threads thoroughly before installation. Apply anti-seize compound for high-temperature zones.
• Maintain minimum bend radius of 25.4 mm (1.0 in) on the probe cable to preserve signal quality.
• Cross-talk limitation requires a flat target of at least 30.5 mm diameter for accurate readings.

Frequently Asked Questions (FAQ)

Q1: Is the Bently Nevada 330709-000-080-50-12-00 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 330709-000-080-50-12-00 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: Why does this model have agency approval option 00?
Option 00 means "Not required" – this probe suits non-hazardous industrial environments without special certifications. For hazardous areas, choose option 05 (Multiple Approvals).

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 330709-000-080-50-12-00 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.
