-
Recommended Torque: 21.1 N·m (187 in·lb); maximum rated 63.3 N·m (560 in·lb).
-
Minimum Bend Radius: 25.4 mm (1.0 in) even with stainless steel armor.
-
Cross-talk Limitation: Minimum flat target diameter 30.5 mm, shaft diameter 152 mm.
Application Fields
The Bently Nevada 330709-000-080-50-01-05 3300 XL Proximity Probe excels in turbomachinery, compressors, pumps, and large motors. In a steam turbine installation, the probe’s 5-meter cable connects seamlessly to a compatible Proximitor sensor, providing accurate shaft vibration data to prevent catastrophic failure. Its PPS tip and stainless steel case withstand high temperatures and corrosive atmospheres common in petrochemical plants, reducing replacement frequency and maintenance costs.
Installation and Setup Guidance
Correct installation of the Bently Nevada 330709-000-080-50-01-05 is critical for reliable readings. Mount the probe with the recommended torque of 21.1 N·m (187 in·lb) to avoid thread damage. Ensure the M16x1.5 thread engagement does not exceed 24 mm. Use finger-tight torque for connector-to-connector connections (max 0.565 N·m). Avoid cable bends tighter than 25.4 mm. Verify the target surface meets minimum diameter requirements (flat surface 30.5 mm, shaft 152 mm).
Maintenance and Reliability
To maximize ROI from your Bently Nevada 330709-000-080-50-01-05, schedule periodic visual inspections of the probe cable and connector for signs of wear. The probe operates reliably from -52°C to +177°C, but avoid prolonged exposure below -34°C to protect the pressure seal. The 5-meter cable is designed specifically for 5-meter Proximitor sensors—using mismatched lengths degrades accuracy. By adhering to these practices, users minimize downtime and extend probe life, delivering a strong return on investment.
Selection Guide and Purchasing Advice
When selecting the Bently Nevada 330709-000-080-50-01-05 3300 XL Proximity Probe, confirm the thread type (M16x1.5), overall case length (80 mm), total length (5.0 m), and connector option (ClickLoc with protector). Ensure your system uses a compatible 5-meter Proximitor sensor. For genuine parts and competitive pricing, choose UBEST Automation (ubest101) as your supplier.
