Parameter Analysis

The 330709-000-080-10-02-05 offers a linear measurement range suitable for most rotating machinery applications. The 1.0 m total length provides flexibility for installation. The probe’s DC resistance of 5.9 ± 0.5 ohms ensures consistent performance with compatible proximitors. The M16 x 1.5 thread allows secure mounting, and the stainless steel case provides durability in harsh environments.

Application Scenarios

This proximity probe is ideal for monitoring vibration and axial position in turbines, compressors, pumps, and other rotating machinery. It is commonly used in oil & gas, power generation, and petrochemical industries where reliable condition monitoring is critical.

Installation Guide

Install the probe with a recommended torque of 21.1 N•m (187 in•lb) for the case. Ensure the target surface is flat and has a minimum diameter of 30.5 mm (1.2 in) for flat surfaces, or a shaft diameter of at least 152 mm (6.0 in). Maintain a minimum bend radius of 25.4 mm for the cable. Connect the ClickLoc connector to the extension cable or proximitor, tightening finger tight only.

Compatibility

The 330709-000-080-10-02-05 is compatible with Bently Nevada 3300 XL extension cables and proximitors (e.g., 3300 XL 11 mm proximitor). It is designed for use with 3300 and 3500 monitoring systems.

Maintenance Advice

Regularly inspect the probe tip for damage or contamination. Ensure the cable is not bent beyond the minimum radius. Check connector tightness periodically. Avoid exposing the probe to temperatures below -34°C (-30°F) as this may cause premature failure of the pressure seal.

Procurement Advice

When ordering, verify the model number 330709-000-080-10-02-05 to ensure correct specifications. Confirm the total length, thread type, and connector option match your requirements. Consider purchasing spare probes to minimize downtime.
