Bently Nevada 330101-00-40-10-11-05 3300 XL 8 mm Probe, 3/8-24 UNF Thread

Technical Specifications Breakdown

Key parameters for the 330101-00-40-10-11-05 are listed below for quick reference:

Industry Applications

Turbine and Compressor Monitoring

For steam turbines and centrifugal compressors, the 330101-00-40-10-11-05 provides critical shaft vibration data. Its 2 mm linear range and -9 Vdc recommended gap setting for radial vibration enable precise monitoring of rotor dynamics, helping operators avoid catastrophic failures.

Pump and Motor Protection

In large pumps and motors, early detection of shaft misalignment or bearing wear is essential. This probe’s robust PPS tip and stainless steel case withstand harsh conditions, while the FluidLoc cable prevents oil leakage along the cable path—a common issue in lubricated machinery.

Process Industry Reliability

In refineries and chemical plants, equipment must operate continuously. The CSA, ATEX, and IECEx approvals ensure the probe meets international safety standards for hazardous locations, reducing compliance risks.

Installation & Setup Guidance

When installing the 330101-00-40-10-11-05, ensure the target surface is clean and free of magnetic irregularities. Use the recommended field wiring: 0.2 to 1.5 mm² (16 to 24 AWG) three-conductor shielded triad cable. The maximum distance between the 3300 XL Proximitor Sensor and the monitor is 305 meters (1,000 feet). Set the initial gap to approximately -9 Vdc (about 1.27 mm or 50 mils) for radial vibration measurements. Verify the probe’s TipLoc and CableLoc features provide a secure bond—the cable offers 330 N (75 lbf) pull strength.

Reliability in Harsh Environments

In rotating machinery, unplanned downtime often stems from undetected shaft vibration. The Bently Nevada 330101-00-40-10-11-05 3300 XL 8 mm probe directly addresses this challenge by providing accurate, non-contact displacement measurements. This component is engineered for continuous operation in demanding industrial settings, helping maintenance teams identify developing faults before they cause failure.

Maintenance & Reliability

Inspect the probe and cable periodically for physical damage, especially near the connector and probe tip. Although the probe is designed to seal differential pressure with a Viton O-ring, it is not pressure tested before shipment. If your application requires a pressure seal test, contact the custom design department. Avoid exposing the probe to temperatures below -34°C (-30°F) to prevent premature failure of the pressure seal. The probe’s relative humidity tolerance is —less than a 3% change in Average Scale Factor after 56 days at 93% humidity per IEC 68-2-3.

Compatibility & Integration

The 330101-00-40-10-11-05 is part of the 3300 XL series and works with Bently Nevada Proximitor sensors and monitoring systems. The miniature coaxial ClickLoc connector ensures reliable signal transmission, and the FluidLoc cable option prevents liquid ingress. For optimal performance, use the probe with compatible extension cables and monitors from the same series.

Selection Guide & Purchasing Advice

When selecting a replacement or new probe, verify that the thread type (3/8-24 UNF) and overall length match your installation requirements.
