Bently Nevada 330101-20-35-10-02-00 3300 XL 8 mm Probe

Technical Specifications Breakdown

Key parameters for the 330101-20-35-10-02-00 are listed below for quick reference:

Industry Applications

Turbine Radial Vibration Monitoring

Its 2 mm linear range and 7.87 V/mm scale factor deliver reliable data for protection systems.

Compressor Shaft Position Sensing

In centrifugal compressors, the 3300 XL 8 mm probe monitors axial and radial position. The robust PPS tip and stainless steel case withstand harsh environments.

Pump Condition Monitoring

For large pumps, early detection of shaft displacement prevents seal and bearing damage. The probe's miniature coaxial ClickLoc connector simplifies field wiring.

Installation & Setup Guidance

Mount the probe using the 3/8-24 UNF thread into a properly tapped hole. Ensure the target surface is clean and within the recommended gap setting of -9 Vdc (approximately 1.27 mm or 50 mils) for radial vibration. Use 3-conductor shielded triad cable for field wiring, with a maximum length of 305 meters (1,000 feet) between the probe and the monitor. Verify the incremental scale factor over the linear range during commissioning.

Maintenance & Reliability

Inspect the probe tip and cable periodically for physical damage. The patented TipLoc and CableLoc designs provide 330 N (75 lbf) pull strength for secure attachment. Avoid exposing the probe to temperatures below -34°C (-30°F) to prevent premature pressure seal failure. The Viton O-ring seals differential pressure, but the probe is not pressure tested before shipment.

Preventing Unplanned Downtime with Precision Vibration Sensing

In rotating machinery, undetected shaft vibration can lead to catastrophic bearing failure and costly production halts. The Bently Nevada 330101-20-35-10-02-00 3300 XL 8 mm Probe provides the rugged, accurate displacement measurement needed for early fault detection. This probe is designed for radial vibration and position monitoring in critical assets like turbines, compressors, and pumps.

Compatibility & Integration

This probe works with Bently Nevada 3300 XL extension cables and Proximitor sensors. The standard 1.0 meter system offers an incremental scale factor of 7.87 V/mm ± 5% over 0°C to +45°C. For extended temperature range applications, the probe tip can operate up to +218°C.

Selection Guide & Purchasing Advice

When selecting a vibration probe, consider the unthreaded length, overall case length, and cable connector type. Contact AutoDCSTech to verify current lifecycle status and availability before ordering.
