Bently Nevada 330101-33-53-10-12-05 3300 XL 8 mm Probe, 3/8-24 UNF Thread, Without Armor

Robust Vibration Monitoring with the Bently Nevada 3300 XL 8 mm Probe

Industrial rotating machinery demands precise and reliable vibration monitoring to prevent costly downtime and catastrophic failures. The Bently Nevada 330101-33-53-10-12-05, a 3300 XL 8 mm probe with 3/8-24 UNF thread and without armor, delivers the accuracy and durability required for critical asset protection. This probe is designed for eddy-current displacement measurement, providing a linear output proportional to shaft vibration and position.

Technical Specifications Breakdown

Key parameters for the 330101-33-53-10-12-05 are listed below for quick reference:

Industry Applications and Failure Prevention

The patented TipLoc molding method provides a more robust bond between the probe tip and the probe body, while the CableLoc design delivers 330 N (75 lbf) pull strength. The optional FluidLoc cable prevents oil and other liquids from leaking out of the machine through the cable’s interior. By using this probe, engineers can detect early signs of bearing wear, unbalance, and misalignment, enabling proactive maintenance that reduces unplanned downtime.

Installation and Setup Guidance

Proper installation is critical for accurate measurements. The 330101-33-53-10-12-05 uses a 3/8-24 UNF thread for mounting. The recommended gap setting for radial vibration is -9 Vdc, approximately 1.27 mm (50 mils). Field wiring should use 0.2 to 1.5 mm² (16 to 24 AWG) three-conductor shielded triad cable with tinned field wiring. The maximum length between the 3300 XL Proximitor Sensor and the monitor is 305 meters (1,000 feet). Ensure the probe tip is clean and free of debris before installation.

Maintenance and Reliability

The probe case is made from AISI 303 or 304 stainless steel, offering corrosion resistance. The probe tip material is PPS, providing a thicker encapsulation for enhanced ruggedness. The standard probe operates from -52°C to +177°C. Exposing the probe to temperatures below –34°C (–30°F) may cause premature failure of the pressure seal. Inspect the cable and connector periodically for damage. The probe is designed to seal differential pressure between the probe tip and case using a Viton O-ring.

Compatibility and Integration

This probe is part of the Bently Nevada 3300 XL series and is designed for use with 3300 XL Proximitor Sensors and compatible monitoring systems. The miniature coaxial ClickLoc connector ensures a secure and reliable connection. The unit carries CSA, ATEX, and IECEx approvals, making it suitable for hazardous area installations.
