Installation & Setup Guidance
Proper installation of the 330708-00-24-90-01-00 is critical for accurate readings. Mount the probe with the 5/8-18 UNF thread into the machine case. Ensure thread engagement does not exceed 0.938 inches. Tighten the probe case to the recommended torque of 15.2 N·m (133 in·lb) using a torque wrench. Do not exceed 45.2 N·m. The connector-to-connector torque should be finger tight only, with maximum 0.565 N·m (5 in·lb). Ensure the minimum bend radius of 25.4 mm (1.0 in) for the cable is maintained to prevent damage.
Maintenance & Reliability
The robust stainless steel case and PPS tip provide excellent corrosion resistance and thermal stability. The Bently Nevada 330708-00-24-90-01-00 operates reliably from -51°C to +177°C. For continuous vibration monitoring, periodic inspection of the connector and cable integrity is recommended. Exposing the probe to temperatures below -34°C (-30°F) may cause premature seal failure. Regular calibration verification ensures measurement accuracy, extending service life and reducing long-term costs.
Selection Guide & Purchasing Advice
When selecting the Bently Nevada 330708-00-24-90-01-00, confirm your application requires a 9-meter cable with miniature coaxial ClickLoc connector. Ensure the thread size (5/8-18) matches your mounting point. This probe is ideal for steam turbines, compressors, and large pumps.
