Precision Measurement for Rotating Machinery
This probe delivers a linear range of 2 mm (80 mils), starting at approximately 0.25 mm (10 mils) from the target. The recommended gap setting for radial vibration is -9 Vdc, corresponding to about 1.27 mm (50 mils). With an incremental scale factor of 7.87 V/mm (200 mV/mil) ± 5%, it provides consistent, repeatable measurements critical for early fault detection.
Industry Applications
- Turbine Monitoring: The probe's robust stainless steel case and PPS tip withstand high temperatures up to +177°C, making it suitable for steam and gas turbine bearing vibration monitoring.
- Compressor Protection: In reciprocating and centrifugal compressors, the 3300 XL probe detects shaft displacement changes that indicate wear or imbalance, helping prevent catastrophic failures.
- Pump Vibration Analysis: For critical pumps in oil and gas or water treatment, this probe offers the sensitivity needed to identify developing faults before they cause downtime.

Installation and Setup Guidance
When installing the 330101-01-29-10-01-CN, ensure the target surface is clean and within the specified linear range. Use the recommended gap setting of -9 Vdc for radial vibration applications. Field wiring should use 0.2 to 1.5 mm² (16 to 24 AWG) three-conductor shielded triad cable, with a maximum length of 305 meters (1,000 feet) between the probe and monitor. The miniature coaxial ClickLoc connector simplifies connection while providing reliable signal integrity.
Maintenance and Reliability
Regularly inspect the probe cable and connector for signs of wear or damage. The probe is designed to seal differential pressure between tip and case using a Viton® O-ring. Avoid exposing the probe to temperatures below -34°C (-30°F) to prevent premature pressure seal failure. For applications requiring pressure seal testing, contact the custom design department.
Reliable Vibration Sensing for Critical Machinery
When unplanned downtime threatens production targets, accurate vibration measurement is essential. The Bently Nevada 330101-01-29-10-01-CN 3300 XL 8 mm Probe provides the robust performance needed for continuous monitoring of rotating equipment. This probe is designed to withstand harsh industrial environments while delivering precise displacement data.
Robust Construction for Demanding Environments
The 330101-01-29-10-01-CN features a patented TipLoc molding method that creates a stronger bond between the probe tip and body. Its cable incorporates a CableLoc design offering 330 N (75 lbf) pull strength, ensuring secure attachment even under stress. The probe case is made from AISI 303 or 304 stainless steel, providing corrosion resistance. The probe tip material is polyphenylene sulfide (PPS), which offers durable encapsulation of the coil.

Compatibility and Integration
This probe is part of the Bently Nevada 3300 XL series and is designed for use with compatible Proximitor sensors and monitoring systems. The extension cable capacitance is 69.9 pF/m (21.3 pF/ft) typical. For extended temperature range applications, probe tips can operate up to +218°C (+425°F).
Selection Guide and Purchasing Advice
When selecting the 330101-01-29-10-01-CN, verify that the thread size (3/8-24 UNF) and cable length (1.0 meter) meet your installation requirements. This probe does not include armor; if additional protection is needed, consider armored options. Please verify current lifecycle status and availability with AutoDCSTech before ordering.
