Product Overview
The Bently Nevada 330708-00-10-10-11-00 is a 3300 XL 11 mm proximity probe manufactured in the USA. This probe features a 5/8-18 UNF thread, a polyphenylene sulfide (PPS) tip, and an AISI 304 stainless steel case. The unthreaded length is 0 inches, overall case length is 1.0 inch, and total probe length is 1.0 metre (3.3 feet). It includes a miniature coaxial ClickLoc connector with connector protector and FluidLoc cable, ensuring reliable signal transmission in harsh industrial environments. As a direct upgrade from older 3300 series probes, the 330708-00-10-10-11-00 delivers improved performance and durability.
Installation Guide
Proper installation of the Bently Nevada 330708-00-10-10-11-00 minimizes signal noise and mechanical damage. For the 5/8-18 UNF thread, the maximum length of thread engagement is 0.938 inches. Apply torque within recommended limits: maximum rated torque is 45.2 N·m (400 in·lb), and recommended torque is 15.2 N·m (133 in·lb). For connector-to-connector connections, use finger tight as recommended, with a maximum torque of 0.565 N·m (5 in·lb). The minimum bend radius for the cable is 25.4 mm (1.0 in). Ensure the probe is properly sealed to maintain differential pressure integrity.
Maintenance and Reliability
The Bently Nevada 330708-00-10-10-11-00 operates within a temperature range of -52°C to +177°C (-62°F to +351°F). Note that exposing the probe to temperatures below -34°C (-30°F) may cause premature failure of the pressure seal. The probe cable is 75 Ω triaxial, fluoroethylene propylene (FEP) insulated, available in total probe lengths of 1, 5, or 9 metres. Regularly inspect the cable and connector for damage. The probe tip material (PPS) withstands harsh conditions, and the case material (304 SST) resists corrosion. Shipping weight is 0.17 kg.
Compatibility and Integration
This 3300 XL probe is designed for direct replacement of older Bently Nevada 3300 series probes. The Bently Nevada 330708-00-10-10-11-00 works seamlessly with standard Bently Nevada monitoring systems that accept proximity probe inputs. Verify thread size, total length, and connector type to ensure compatibility with your existing installation.
Selection Guide
Before purchasing the Bently Nevada 330708-00-10-10-11-00, confirm the required thread size (5/8-18 UNF), total probe length (1.0 m), and connector type (miniature coaxial ClickLoc with FluidLoc cable). For custom lengths or armored options, contact UBEST Automation. We provide genuine Bently Nevada parts with reliable support.
Troubleshooting and Common Issues
Common issues with proximity probes include signal drift and pressure seal failure. For the Bently Nevada 330708-00-10-10-11-00, seal failure can occur if the probe is exposed to temperatures below -34°C for extended periods. Ensure proper torque settings during installation to avoid thread damage. If signal noise appears, check the cable for bend radius violations or connector tightness. The probe dc resistance measured from center conductor to outer conductor for a 1.0 m probe is 5.9 ± 0.5 ohms; deviations may indicate a cable fault.
