Industry Applications
The Bently Nevada 330709-000-030-50-02-05 excels in vibration monitoring for turbines, compressors, pumps, and motors. Its 11 mm probe tip and M16 x 1.5 thread allow easy installation into standard mounting holes. The probe’s cross-talk limitation ensures accurate readings even on small shaft diameters (minimum 152 mm recommended). In petrochemical and power generation plants, this probe replaces older models to enhance machine protection and reduce unplanned downtime.
Installation & Setup Guidance
When replacing an existing probe with the Bently Nevada 330709-000-030-50-02-05, ensure the mounting hole is clean and the thread engagement does not exceed 24 mm. Apply the recommended torque of 21.1 N·m (187 in·lb) to the probe case. For the connector, finger-tighten only; maximum torque is 0.565 N·m (5 in·lb). Maintain a minimum bend radius of 25.4 mm (1.0 in) for the cable. This probe is designed for use with the five-meter Proximitor Sensor only.
Selection Guide & Purchasing Advice
Before purchasing, verify that your existing system uses the five-meter Proximitor Sensor and that the cable length (5.0 m) is suitable. The Bently Nevada 330709-000-030-50-02-05 comes with a miniature coaxial ClickLoc connector. For support or to confirm compatibility, contact UBEST Automation.
