Parameter Analysis
The 5.0-meter probe length is specifically designed for use with the five-meter Proximitor sensor, ensuring optimal signal integrity. The miniature coaxial ClickLoc connector provides secure and reliable connections. The probe’s DC resistance of 7.2 ± 0.8 ohms is within the specified range for accurate eddy-current sensing. The PPS tip and stainless steel case offer excellent environmental resistance.
Application Scenarios
This 330709-000-080-50-02-00 probe is ideal for monitoring vibration and position in turbines, compressors, pumps, and other rotating machinery. It is commonly used in critical applications where precise measurement is essential for predictive maintenance and machine protection.
Installation Guide
Ensure the probe is mounted with the recommended torque of 21.1 N•m (187 in•lb) and not exceeding 63.3 N•m (560 in•lb). The thread engagement length should be a maximum of 24 mm. Maintain a minimum bend radius of 25.4 mm (1.0 in) for the cable. For optimal performance, follow the target size and shaft diameter recommendations: minimum flat surface diameter of 30.5 mm and minimum shaft diameter of 152 mm.
Compatibility
This probe is designed for use with Bently Nevada 3300 XL systems and is compatible with the five-meter Proximitor sensor. It is not compatible with other Proximitor lengths.
Maintenance Advice
Regularly inspect the probe and cable for damage. Avoid exposing the probe to temperatures below -34°C (-30°F) to prevent premature failure of the pressure seal. Clean the probe tip with a soft cloth and approved solvent if contamination occurs.
Procurement Advice
When ordering the 330709-000-080-50-02-00, verify the model number and specifications to ensure it meets your application requirements. Consider purchasing spare probes to minimize downtime. Authorized Bently Nevada channels like TenBN offer genuine products and technical support.
