Parameter Analysis

The 330709-000-080-90-12-00 offers a 9.0-meter cable length, ideal for installations where the probe must be routed over a distance to the proximitor. The 80 mm case length provides flexibility for various mounting configurations. The 11 mm probe size delivers a linear range suitable for most rotating machinery applications. The DC resistance of 8.5 ± 1.1 ohms ensures consistent performance with Bently Nevada monitoring systems.

Application Scenarios

This proximity probe is widely used for vibration and position monitoring in turbines, compressors, pumps, and other rotating machinery. It is suitable for applications requiring reliable measurement of shaft radial vibration, axial position, and speed/phase reference.

Installation Guide

Install the probe into a mounting hole with M16 x 1.5 thread. Ensure the unthreaded length (0 mm) and case length (80 mm) meet your mounting requirements. Tighten the probe case to the recommended torque of 21.1 N•m (187 in•lb). Connect the ClickLoc connector to the extension cable, tightening 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. Observe temperature limits: avoid exposing the probe below -34°C as it may cause premature failure of the pressure seal.

Compatibility

This probe is compatible with Bently Nevada 3300 XL monitoring systems, including 3500 series monitors and associated proximitors. It is designed to work with 3300 XL extension cables and is part of the 3300 XL family.

Maintenance Advice

Regularly inspect the probe tip and cable for damage. Keep the connector clean and dry. Ensure that the probe is not subjected to temperatures outside the specified range. Check torque periodically to maintain proper installation.

Procurement Advice

When ordering, verify the model number 330709-000-080-90-12-00 to ensure it matches your requirements. Confirm the total length (9.0 m), connector type (ClickLoc), and thread size (M16 x 1.5). For applications requiring agency approvals, select the appropriate option. Contact TenBN for availability and technical support.

FAQ

What is the temperature range of this probe?

The operating and storage temperature range is -52°C to +177°C (-62°F to +351°F). However, exposing the probe to temperatures below -34°C may cause premature failure of the pressure seal.

What is the recommended torque for installation?

The recommended probe case torque is 21.1 N•m (187 in•lb). For the connector, use finger-tight, with a maximum of 0.565 N•m (5 in•lb).

Can this probe be used with 3500 series monitors?

Yes, the 330709-000-080-90-12-00 is compatible with Bently Nevada 3500 series monitoring systems when used with appropriate proximitors and extension cables.

What is the minimum shaft diameter for accurate measurement?

For a flat target surface, the recommended minimum shaft diameter is 152 mm (6.0 inches).
