Parameter Analysis

The 330709-000-230-50-01-05 probe has a DC resistance of 7.2 ± 0.8 ohms, ensuring accurate signal transmission. The recommended minimum target flat surface diameter is 30.5 mm (1.2 in), and the minimum shaft diameter is 152 mm (6.0 in) to avoid cross-talk limitations. The probe case torque recommended is 21.1 N•m (187 in•lb), with a maximum rated torque of 63.3 N•m (560 in•lb). The connector-to-connector torque is finger tight (maximum 0.565 N•m). The minimum bend radius is 25.4 mm (1.0 in).

Application Scenarios

This proximity probe is ideal for monitoring vibration and position in critical rotating machinery such as turbines, compressors, pumps, and other industrial equipment. It is commonly used in applications requiring high reliability and accuracy, including power generation, oil & gas, and manufacturing.

Installation Guide

When installing the 330709-000-230-50-01-05, ensure the probe case thread is properly engaged (maximum thread engagement 24 mm). Use the recommended torque of 21.1 N•m for the probe case. The connector should be finger tight, with a maximum torque of 0.565 N•m. Avoid bending the cable beyond the minimum bend radius of 25.4 mm. For temperatures below -34°C, premature failure of the pressure seal may occur, so take precautions.

Compatibility

This probe is designed for use with the five-meter Proximitor Sensor only. It is part of the 3300 XL series and is compatible with Bently Nevada monitoring systems that support 3300 XL 11 mm probes.

Maintenance Advice

Regularly inspect the probe and cable for damage. Keep the probe tip clean and free from contaminants. Ensure connectors are properly tightened and protected. Avoid exposing the probe to temperatures below -34°C to prevent pressure seal failure.

Procurement Advice

When purchasing the 330709-000-230-50-01-05, verify the total length and connector type to ensure compatibility with your system. Confirm the agency approvals meet your site requirements. Consider purchasing from authorized distributors to guarantee genuine parts and warranty support.
