The miniature coaxial ClickLoc connector ensures secure and quick installation. The probe is designed to meet cross-talk limitations with a recommended minimum target flat surface diameter of 30.5 mm and shaft diameter of 152 mm. Its robust construction and temperature ratings make it suitable for harsh industrial environments.

Application Scenarios

This proximity probe is widely used for radial vibration and axial position measurements in turbines, compressors, pumps, and other rotating machinery. It is compatible with Bently Nevada 3300 and 3500 monitoring systems, providing accurate data for predictive maintenance and machine protection.

Installation Guide

Install the probe using the recommended torque of 21.1 N·m (187 in·lb) for the M16 x 1.5 case. Ensure the connector is finger tight, with a maximum torque of 0.565 N·m. Maintain a minimum bend radius of 25.4 mm for the cable. Verify the target surface meets the recommended minimum size and that the gap is set according to the system requirements.

Compatibility

The 330710-000-050-10-02-00 is part of the 3300 XL series and is compatible with Bently Nevada 3300/3500 racks, proximitors, and extension cables. It uses a miniature coaxial ClickLoc connector, which is standard for this series.

Maintenance Advice

Regularly inspect the probe cable and connector for damage. Keep the probe tip clean and free from debris. Avoid exposing the probe to temperatures below -34°C as this may cause premature failure of the pressure seal. Calibration checks should be performed periodically to ensure measurement accuracy.

Procurement Advice

When ordering, verify the model number 330710-000-050-10-02-00 to ensure correct configuration. Consider purchasing spare probes to minimize downtime. For applications requiring pressure testing or custom configurations, contact our custom design department.
