Industry Applications
The Bently Nevada 330709-000-060-50-11-05 3300 XL probe excels in rotating machinery monitoring. Common applications include:
-
Steam and gas turbines – vibration and shaft displacement measurement.
-
Centrifugal compressors – radial and axial position monitoring.
-
Industrial pumps and motors – early detection of bearing wear and misalignment.
With a recommended minimum shaft diameter of 152 mm and a flat target surface of 30.5 mm, this probe ensures accurate cross-talk limited readings.
Installation & Setup Guidance
Proper installation is critical for accurate measurements. Follow these guidelines based on the Bently Nevada 330709-000-060-50-11-05 specifications:
-
Torque: Tighten the probe case to 21.1 N·m (187 in·lb) – never exceed 63.3 N·m.
-
Thread Engagement: Do not exceed 24 mm into the mounting hole.
-
Connector: Use finger-tight torque for the ClickLoc connector; maximum 0.565 N·m (5 in·lb).
-
Cable Bending: Maintain a minimum bend radius of 25.4 mm to avoid damage.
-
Temperature: Avoid exposing the probe to temperatures below -34°C for extended periods to protect the pressure seal.
This probe is designed for use with a five-meter Proximitor sensor only. Ensure matching lengths for proper operation.
