Industry Applications
The Bently Nevada 330709-000-070-50-12-05 is ideal for upgrading vibration monitoring in turbines, compressors, and pumps. Its 5.0 meter cable length suits installations where the Proximitor sensor is located remotely. The PPS tip and 304 SST case ensure durability in harsh environments. Use it as a direct replacement for older 3300 XL series probes to gain improved temperature ratings and connector reliability.
Installation & Setup Guidance
Mount the probe using the M16 x 1.5 thread. Ensure maximum thread engagement of 24 mm. Apply recommended torque of 21.1 N·m (187 in·lb) for the probe case. For connector-to-connector connections, use finger-tight torque, not exceeding 0.565 N·m (5 in·lb). Observe minimum bend radius of 25.4 mm to avoid cable damage. The miniature coaxial ClickLoc connector provides secure attachment to the extension cable.
Maintenance & Reliability
Regular inspection of the probe cable and connector is recommended. The probe withstands operating temperatures from -52°C to +177°C. Note that exposure below -34°C may cause premature seal failure. Select the appropriate temperature classification for your environment: the probe supports classes from T1 to T5 for gas and dust atmospheres. The 304 SST case and PPS tip resist corrosion and wear, extending service life.
Selection Guide & Purchasing Advice
Before purchasing, verify that your system uses a five meter Proximitor sensor, as this probe is designed for that length. Confirm the connector type (Miniature coaxial ClickLoc) and cable type (FluidLoc). For assistance with compatibility or replacement needs, contact UBEST Automation or visit ubest101.myshopify.com. Ensure your application's temperature range falls within the probe's ratings.
