-
Cable Specification: 75 Ω triaxial, FEP insulated cable available in 1, 5, or 9 metre lengths.
-
Agency Approvals: Multiple approvals (option 05) for diverse industrial environments.
Industry Applications
This 3300 XL 11 mm proximity probe is ideal for vibration monitoring in rotating machinery such as steam turbines, centrifugal compressors, and large pumps. The Bently Nevada 330707-00-62-10-12-05 provides accurate gap voltage measurements for shaft displacement and eccentricity. Its PPS tip and 304 stainless steel case withstand harsh conditions in refineries and power plants.
Installation & Setup Guidance
Install the Bently Nevada 330707-00-62-10-12-05 with care. For 5/8-18 threads, thread engagement must not exceed 0.938 inches. Apply the recommended torque of 15.2 N·m (133 in·lb) to avoid damaging the probe case. The connector-to-connector torque should be finger tight, maximum 0.565 N·m (5 in·lb). Minimum bend radius for the cable is 25.4 mm (1.0 inch). Ensure the probe is not exposed to temperatures below -34°C (-30°F) during installation to preserve the pressure seal.
Maintenance & Reliability
Routine maintenance involves inspecting the cable for cuts or kinks. The Viton O-ring seals differential pressure between tip and case; avoid exceeding the temperature limits to prevent premature seal failure. The Bently Nevada 330707-00-62-10-12-05 operates reliably in environments from -51°C to +177°C. Store probes in clean, dry conditions within the same temperature range. Replacing older probes with this model reduces downtime and improves data accuracy, offering long-term cost benefits.
Selection Guide & Purchasing Advice
Before ordering, verify your system requirements: confirm thread size (5/8-18 UNF), total length (1.0 metre), and connector type (miniature coaxial ClickLoc). The Bently Nevada 330707-00-62-10-12-05 is direct replacement for many 3300 XL probes. For guaranteed authenticity and fast shipping, choose UBEST Automation as your supplier.
