Parameter Analysis

The 330709-000-230-10-11-05 probe is engineered for high accuracy and stability. Its 11 mm sensing element provides excellent linearity and resolution for vibration and displacement measurements. The probe’s DC resistance of 5.9 ± 0.5 ohms ensures consistent performance with compatible proximitors. The recommended minimum target size (flat surface) is 30.5 mm diameter, and the recommended minimum shaft diameter is 152 mm, ensuring reliable readings in typical rotating machinery applications. The probe’s temperature range and material selection make it suitable for harsh environments.

Application Scenarios

This proximity probe is ideal for monitoring radial vibration, axial position, and shaft eccentricity in turbines, compressors, pumps, and other rotating equipment. It is commonly used in machinery protection systems, condition monitoring, and performance analysis. The probe’s robust design and multiple approvals make it suitable for use in hazardous areas and critical industrial processes.

Installation Guide

Proper installation is crucial for accurate measurements. The probe should be mounted with the recommended torque of 21.1 N•m (187 in•lb) for the M16x1.5 case. Ensure the thread engagement does not exceed 24 mm. The connector should be finger tight, with a maximum torque of 0.565 N•m (5 in•lb). Maintain a minimum bend radius of 25.4 mm for the cable. Follow the manufacturer’s guidelines for gap setting and target specifications to achieve optimal performance.

Compatibility

The 330709-000-230-10-11-05 is part of the 3300 XL series and is compatible with Bently Nevada 3300 XL proximitors and extension cables. It is designed to work with standard 3300 series monitoring systems. For specific system integration, refer to the product manual or consult with TenBN technical support.

Maintenance Advice

Regularly inspect the probe tip and cable for damage or wear. Ensure connectors are clean and properly torqued. Avoid exposing the probe to temperatures below -34°C (-30°F) as this may cause premature failure of the pressure seal. Periodic calibration checks are recommended to maintain measurement accuracy.

Procurement Advice

When ordering, verify the model number 330709-000-230-10-11-05 to ensure it matches your requirements. Confirm the total length and connector type. For large quantities or custom requirements, contact TenBN for availability and lead times. Ensure you purchase from an authorized channel to guarantee genuine Bently Nevada quality.
