Product Introduction
When precise vibration monitoring is critical, the Bently Nevada 330709-000-060-50-01-05 3300 XL 11 mm Proximity Probe delivers reliable performance. Designed for industrial machinery protection, this probe measures shaft vibration and position with high accuracy. Its 5.0-meter (16.4 feet) total length works exclusively with the five-meter Proximitor sensor.

Installation & Setup Guidance
Correct mounting ensures accurate readings. Use the M16x1.5 thread to install the probe into a tapped hole. Engage threads up to 24 mm maximum. Tighten the probe case to the recommended torque of 21.1 N·m (187 in·lb) and never exceed 63.3 N·m. The miniature coaxial ClickLoc connector requires only finger-tight torque; overtightening damages the connector. Route the cable with a minimum bend radius of 25.4 mm (1.0 in) to avoid internal stress.
Maintenance & Reliability
This probe withstands harsh environments. The PPS tip resists chemicals and abrasion. Follow the temperature schedule for ambient classifications: for T1 use up to +232°C, T2 up to +177°C, etc. Avoid exposing the probe below -34°C (-30°F) as it may cause premature pressure seal failure. Periodic inspection of the cable and connector for wear ensures long service life.
Troubleshooting & Common Issues
Cross-talk between adjacent probes can affect readings. Maintain the recommended minimum target flat surface diameter of 30.5 mm (1.2 in) and shaft diameter of 152 mm (6.0 in). If measurement drift occurs, verify cable continuity: the probe DC resistance should be 7.2 ± 0.8 Ω. Temperature extremes outside the -52°C to +177°C range may degrade performance. Ensure the Proximitor sensor matches the 5.0-meter probe length.
Selection Guide & Purchasing Advice
The Bently Nevada 330709-000-060-50-01-05 is a complete assembly with a 5.0-meter cable and ClickLoc connector. Confirm your system requires the five-meter length and multiple approvals (Agency Approval Option 05). For replacement or upgrade, verify the existing probe's thread, length, and connector type.
