Centrifugal Compressors: Detect shaft misalignment and dynamic instabilities.
-
Industrial Pumps: Provide early warning of bearing degradation and imbalance.
These scenarios demand reliable performance under harsh conditions, and the 330708-00-24-10-01-00 meets those requirements with its robust construction and proven design.
Installation & Setup Guidance
Proper installation is critical for accurate measurements. For the Bently Nevada 330708-00-24-10-01-00 3300 XL 11 mm Proximity Probe, follow these guidelines:
- Ensure the mounting thread is 5/8-18 UNF. The maximum thread engagement is 0.938 inches.
- Apply the recommended case torque of 15.2 N·m (133 in·lb). Do not exceed 45.2 N·m (400 in·lb).
- When connecting the miniature coaxial ClickLoc connector, tighten finger tight only; maximum torque is 0.565 N·m (5 in·lb).
- Maintain a minimum bend radius of 25.4 mm (1.0 inch) for the probe cable to prevent damage.
- When routing the cable, avoid sharp edges and high-temperature surfaces.
Note: The probe seals differential pressure with a Viton O-ring. While not pressure-tested before shipment, it is designed to seal under normal conditions. If a pressure test is required, contact the manufacturer.
Maintenance & Reliability
The Bently Nevada 330708-00-24-10-01-00 3300 XL 11 mm Proximity Probe is designed for long-term reliability. Key maintenance considerations include:
- Operating temperature range of -51°C to +177°C. However, prolonged exposure below -34°C (-30°F) may lead to premature pressure seal failure.
- Inspect the cable and connector regularly for wear or damage. The FEP insulation provides chemical resistance and high-temperature performance.
- Verify that the probe tip (PPS material) remains clean and free from debris to maintain sensing accuracy.
- Store the probe in a clean, dry environment within the specified temperature range when not in use.
By following these practices, the 330708-00-24-10-01-00 will provide consistent performance over its service life.
