Parameter Analysis

The 330709-000-230-90-11-05 probe length of 9.0 meters provides flexibility for installations where the monitor is remote from the measurement point. The 11 mm tip diameter offers a good balance between sensitivity and target size requirements. The probe’s DC resistance of 8.5 ± 1.1 ohms ensures consistent performance with compatible proximitors. The temperature range of -52°C to +177°C allows use in harsh environments, though exposure below -34°C may affect the pressure seal. The M16x1.5 thread and 230 mm case length are standard for many mounting configurations.

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 reliable, continuous measurement of shaft vibration, axial position, and eccentricity. The 3300 XL series is widely deployed in power generation, oil and gas, petrochemical, and manufacturing facilities.

Installation Guide

Install the probe with the recommended torque of 21.1 N•m (187 in•lb) for the M16x1.5 case. Ensure the target surface meets the recommended minimum flat surface diameter of 30.5 mm (1.2 in) and shaft diameter of 152 mm (6.0 in) to avoid cross-talk limitations. Route the cable with a minimum bend radius of 25.4 mm (1.0 in) to prevent damage. Connect the ClickLoc connector to the extension cable or proximitor, tightening finger tight plus a maximum of 0.565 N•m (5 in•lb). Verify the probe gap according to the system calibration.

Compatibility

The 330709-000-230-90-11-05 is compatible with Bently Nevada 3300 XL extension cables and proximitors, as well as 3500 monitoring systems. It is designed to work with standard 3300 XL system components. For specific compatibility, refer to the product manual or contact TenBN technical support.

Maintenance Advice

Regularly inspect the probe tip and cable for damage or contamination. Clean the probe tip with a soft cloth if necessary. Check the connector for tightness and corrosion. Avoid exposing the probe to temperatures below -34°C (30°F) as this may cause premature failure of the pressure seal. Periodically verify the DC resistance to ensure the probe is within specification.

Procurement Advice

When ordering the Bently Nevada 330709-000-230-90-11-05, confirm the total length, connector type, and approvals match your requirements. Ensure that the probe is sourced from an authorized channel like TenBN to guarantee authenticity and warranty. Consider purchasing spare probes to minimize downtime in critical applications.
