Installation & Setup Guidance
Proper installation of the Bently Nevada 330708-00-24-90-01-05 3300 XL 11 mm Proximity Probe is critical for accurate readings. Verify thread engagement does not exceed 0.938 inches to avoid binding. Apply a recommended torque of 15.2 N·m (133 in·lb) to secure the probe case. For the connector, tighten finger-tight only; maximum torque is 0.565 N·m (5 in·lb). Observe the minimum bend radius of 25.4 mm (1.0 in) for the cable to prevent damage. The probe is designed for a differential pressure seal; ensure the Viton O-ring is seated correctly.
Maintenance & Reliability
To extend service life, avoid exposing the Bently Nevada 330708-00-24-90-01-05 to temperatures below -34°C (-30°F), as this may cause premature failure of the pressure seal. Regularly inspect the cable for cuts or kinks, especially near connectors. The probe operates reliably in the range -52°C to +177°C. Since the probe is not pressure-tested before shipment, verify the seal integrity in your application. Periodic checks of the DC resistance (expect 8.5 ± 1.1 ohms) can indicate cable degradation.
Buying Guide & Selection Advice
When ordering the Bently Nevada 330708-00-24-90-01-05, confirm your system requires a 9.0-meter probe with ClickLoc connector and 5/8-18 UNF thread. For replacement, match the unthreaded length (0 in), overall case length (2.4 in), and agency approval option 05.
