Installation & Setup Guidance
When installing the Bently Nevada 330709-000-030-90-12-00, observe the following: The probe case thread is M16 x 1.5 with a maximum engagement of 24 mm. Tighten the probe case to the recommended torque of 21.1 N·m (187 in·lb); do not exceed the maximum rated torque of 63.3 N·m to avoid damage. The connector should be finger-tight plus a maximum of 0.565 N·m (5 in·lb). Ensure a minimum bend radius of 25.4 mm (1.0 in) to prevent cable stress. For optimal performance, use a flat target surface at least 30.5 mm (1.2 in) in diameter and a shaft diameter of 152 mm (6.0 in) minimum to meet cross-talk limitations.
Maintenance & Reliability
The Bently Nevada 330709-000-030-90-12-00 is built with AISI 304 stainless steel and PPS tip, offering excellent corrosion resistance and thermal stability. Its operating temperature range of -52°C to +177°C ensures suitability for severe environments. To extend service life, avoid exposing the probe to temperatures below -34°C (30°F), which can cause premature pressure seal failure. Regularly inspect the connector and cable for wear; the FluidLoc cable is designed for harsh conditions but should be protected from excessive bending. The probe's DC resistance (8.5 ± 1.1 ohms at 9 meters) serves as a diagnostic tool—any significant deviation may indicate cable damage.
Selection Guide & Purchasing Advice
Before purchasing a replacement or upgrade, verify that the total probe length (9.0 meters) and connector type (miniature coaxial ClickLoc) match your existing system. The 330709-000-030-90-12-00 is a direct fit for Bently Nevada 3300 XL monitor systems. If you require an armored version or different length, consult the full 330709 series.
