Application Scenarios

This 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. The 330709-010-050-10-02-00 is compatible with Bently Nevada 3300 XL systems and can be used with extension cables and proximitors to form a complete monitoring system.

Installation Guide

• Mount the probe using the M16 x 1.5 thread. Recommended torque: 21.1 N•m (187 in•lb). Maximum torque: 63.3 N•m (560 in•lb).
• Ensure the target surface is clean and meets the recommended minimum diameter (30.5 mm flat, 152 mm shaft).
• Connect the probe cable to a compatible extension cable or proximitor using the ClickLoc connector. Finger tight is recommended; maximum torque 0.565 N•m (5 in•lb).
• Maintain a minimum bend radius of 25.4 mm (1.0 in) for the cable.
• Set the proper gap according to your monitoring system requirements.

Compatibility

The 330709-010-050-10-02-00 is part of the 3300 XL series and is compatible with Bently Nevada 3300 XL extension cables and proximitors. It can be used with 3300 XL 11 mm systems. Ensure that the total system length (probe + extension) matches the proximitor calibration requirements.

Maintenance Advice

• Periodically inspect the probe tip and cable for damage or contamination.
• Keep connectors clean and protected from moisture.
• Avoid exposing the probe to temperatures below -34°C (-30°F) as this may cause premature failure of the pressure seal.
• Check torque on mounting threads periodically to ensure secure installation.

Procurement Advice

When ordering the Bently Nevada 330709-010-050-10-02-00, verify the model number to ensure it matches your system requirements. Consider purchasing spare probes for critical machinery to minimize downtime. Ensure you have the correct extension cable and proximitor for your application.
