Application Scenarios

This proximity probe is ideal for monitoring radial 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 essential.

Installation Guide

Install the probe with the recommended torque of 21.1 N•m (187 in•lb). Ensure the thread engagement does not exceed 24 mm. Use a minimum bend radius of 25.4 mm for the cable to avoid damage. For optimal performance, maintain a target size of at least 30.5 mm diameter for flat surfaces and a shaft diameter of at least 152 mm.

Compatibility

The 330709-000-230-10-02-05 is part of the 3300 XL series and is compatible with Bently Nevada 3300/3500 monitoring systems. It works with standard extension cables and proximity transducers.

Maintenance Advice

Regularly inspect the probe tip for contamination or damage. Keep the cable free from sharp bends and abrasion. Verify the dc resistance periodically to ensure the probe is within specification. Avoid exposing the probe to temperatures below -34°C as this may affect the pressure seal.

Procurement Advice

When ordering the Bently Nevada 330709-000-230-10-02-05, confirm the exact model number and options to match your application. Consider purchasing spare probes to minimize downtime. Ensure you source from authorized distributors to guarantee genuine parts and warranty support.
