Parameter Analysis

The 330709-000-080-10-11-00 probe is engineered for accurate gap and vibration measurements. The 11 mm tip diameter provides a linear measurement range suitable for most rotating machinery. The 80 mm case length and 1.0 m cable length offer flexibility in mounting and routing. The M16 x 1.5 thread ensures a secure installation with a recommended torque of 21.1 N•m, preventing loosening under vibration. The probe’s DC resistance of 5.9 ohms is within specification for proper signal transmission. The operating temperature range of -52°C to +177°C allows use in extreme conditions, though exposure below -34°C may affect the pressure seal.

Application Scenarios

This proximity probe is widely used for vibration and position monitoring on critical rotating machinery including turbines, compressors, pumps, and other industrial equipment. It is suitable for radial vibration measurement, axial position monitoring, and speed/phase reference applications when paired with compatible Bently Nevada monitors. The probe’s robust construction and high-temperature rating make it ideal for harsh environments in power generation, oil & gas, and petrochemical industries.

Installation Guide

For optimal performance, install the probe with the recommended torque of 21.1 N•m (187 in•lb) for the M16x1.5 thread. 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) for shaft measurements. Maintain a minimum bend radius of 25.4 mm (1.0 in) for the cable. Connect the ClickLoc connector securely, tightening finger tight plus a maximum of 0.565 N•m (5 in•lb). Avoid exposing the probe to temperatures below -34°C to prevent pressure seal damage.

Compatibility

The 330709-000-080-10-11-00 is compatible with Bently Nevada 3300 XL series monitors and systems, including the 3500 series. It works with standard 3300 XL extension cables and proximitors. The probe uses a miniature coaxial ClickLoc connector, which is compatible with Bently Nevada’s FluidLoc cable system. Ensure that the total system (probe, extension cable, and proximitor) is matched for correct calibration.

Maintenance Advice

Regularly inspect the probe tip and cable for damage or contamination. Clean the probe tip with a soft cloth and appropriate solvent if needed. Check connector tightness periodically to ensure a secure connection. Do not exceed the maximum torque of 63.3 N•m when installing or removing. Store the probe in a clean, dry environment within the specified temperature range. If the probe is exposed to temperatures below -34°C, inspect the pressure seal for integrity.

Procurement Advice

When ordering the Bently Nevada 330709-000-080-10-11-00, verify the model number to ensure it meets your specific requirements, including thread size, case length, and cable length. Consider purchasing spare probes to minimize downtime. Ensure compatibility with your existing Bently Nevada monitoring system. For technical support and genuine parts, contact an authorized Bently Nevada channel like TenBN.
