-
Minimum Bend Radius: 25.4 mm (1.0 in) – prevents cable damage.
These specifications ensure reliable operation and long service life, maximizing return on investment.
Industry Applications
The Bently Nevada 330708-00-24-90-02-00 3300 XL Proximity Probe is ideal for critical rotating machinery such as turbines, compressors, and pumps. Its wide temperature range and rugged construction suit both indoor and outdoor installations. By providing accurate proximity measurements, it enables early detection of shaft vibration and alignment issues, significantly reducing unplanned downtime and repair costs. For end users, this translates to improved asset utilization and lower total cost of ownership.
Installation and Setup
Proper installation of the 330708-00-24-90-02-00 ensures optimal performance. The probe uses a 5/8-18 UNF thread with a maximum engagement length of 0.938 inches. Tighten the probe case to the recommended torque of 15.2 N·m (133 in·lb) – do not exceed 45.2 N·m to avoid damage. The miniature coaxial ClickLoc connector should be finger tight only (max 0.565 N·m). Maintain a minimum bend radius of 25.4 mm on the cable. This probe comes without armor and with standard cable; ensure the cable path avoids sharp edges.
Maintenance and Reliability
Regular inspection of the Bently Nevada 330708-00-24-90-02-00 extends its life and maintains accuracy. Check the cable for cuts or abrasions, especially near connectors. Inspect the Viton O-ring seal for integrity; exposure below -34°C (-30°F) may weaken the pressure seal. Verify connector tightness periodically. The probe’s robust design (PPS tip, 304 SST case) resists corrosion and wear, reducing replacement frequency. Proactive maintenance avoids unexpected failures and supports cost-efficient operations.
Selection Guide
When ordering the Bently Nevada 330708-00-24-90-02-00, confirm the total length option (here 9.0 meters / 29.5 feet), the connector type (miniature coaxial ClickLoc), and that 5/8-18 UNF thread matches your mounting. Verify cable length: 1, 5, or 9 meter options are available. For pressure-tested versions, contact the custom design department.
