Parameter Analysis

The 330709-000-230-50-02-05 is a 5-meter probe, which must be used with a 5-meter Proximitor sensor to ensure correct calibration. The probe’s DC resistance is 7.2 ± 0.8 ohms, critical for system diagnostics. The M16x1.5 thread and 230 mm case length allow for flexible mounting. The miniature ClickLoc connector ensures secure and reliable connection.

Application Scenarios

This probe is ideal for monitoring vibration and position in rotating machinery such as turbines, compressors, pumps, and other industrial equipment. It is suitable for use in hazardous areas with multiple approvals, ensuring compliance with various international standards.

Installation Guide

Install the probe with recommended torque of 21.1 N•m (187 in•lb) for the M16x1.5 case. Ensure the target surface is flat and has a minimum diameter of 30.5 mm (1.2 in) for cross-talk limitation. For shaft applications, the recommended minimum shaft diameter is 152 mm (6.0 in). Maintain a minimum bend radius of 25.4 mm for the cable.

Compatibility

The 330709-000-230-50-02-05 is part of the 3300 XL series and is compatible with Bently Nevada 3300 XL Proximitor sensors (5-meter version). It is designed for use with 3300/3500 monitoring systems.

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 to prevent pressure seal failure. Periodically verify probe resistance to ensure system integrity.

Procurement Advice

When ordering the Bently Nevada 330709-000-230-50-02-05, confirm the total length (5.0 meters) and connector type. Ensure you have the matching 5-meter Proximitor sensor. Verify agency approval requirements for your specific application.
