Bently Nevada 330101-12-40-10-02-05 3300 XL 8 mm Probe

Technical Specifications Breakdown

Key parameters for the 330101-12-40-10-02-05 are listed below for quick reference:

Industry Applications for the 3300 XL Probe

The 8 mm diameter provides a thicker encapsulation of the probe coil in molded PPS plastic, offering enhanced ruggedness against physical abuse. The patented TipLoc molding method ensures a robust bond between the probe tip and body, while the CableLoc design delivers 330 N (75 lbf) pull strength for secure cable attachment. These features make the 330101-12-40-10-02-05 well-suited for applications where probe integrity is critical, such as in oil and gas, power generation, and petrochemical plants.

Installation and Setup Guidance

When installing the 3300 XL 8 mm probe, 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 measurements. The probe uses a 3/8-24 UNF thread for mounting. 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 3300 XL Proximitor Sensor and the monitor. For optimal signal integrity, keep cable runs as short as possible and avoid sharp bends.

Maintenance and Reliability

The probe is designed for long-term reliability in demanding environments. The standard probe operates from -52°C to +177°C (-62°F to +350°F). Exposing the probe to temperatures below –34˚C (-30˚F) may cause premature failure of the pressure seal. The probe case is made from AISI 303 or 304 stainless steel for corrosion resistance. The probe sealing material consists of a Viton O-ring to handle differential pressure between the probe tip and case. Periodic inspection of the probe tip and cable for physical damage is recommended.

Preventing Rotating Machinery Failures with Precision Vibration Monitoring

In high-speed rotating machinery, undetected shaft vibration can lead to catastrophic bearing failure and unplanned downtime. The Bently Nevada 330101-12-40-10-02-05 3300 XL 8 mm Probe delivers the ruggedness and accuracy needed for continuous vibration monitoring in harsh industrial environments. This non-contact eddy current probe provides a linear measurement range of 2 mm (80 mils), starting at approximately 0.25 mm (10 mils) from the target, with an incremental scale factor of 7.87 V/mm (200 mV/mil) ±5% for standard 1 or 5 meter systems. Its robust design helps engineers detect early signs of shaft instability before damage occurs.

Compatibility and Integration

The 330101-12-40-10-02-05 is part of the Bently Nevada 3300 XL family and is compatible with 3300 XL Proximitor Sensors and monitoring systems. The miniature coaxial ClickLoc connector simplifies installation and provides a secure connection. The probe can be ordered with an optional FluidLoc cable option to prevent oil or other liquids from leaking through the cable interior. For standard 1 or 5 meter systems, the incremental scale factor is 7.87 V/mm (200 mV/mil) ±5%.

Selection Guide and Purchasing Advice

When selecting a replacement or new probe, verify the total length, thread type, and connector requirements for your application. The 330101-12-40-10-02-05 offers a 1.0 metre total length with a 3/8-24 UNF thread and miniature coaxial ClickLoc connector. It carries CSA, ATEX, and IECEx approvals for use in hazardous areas.
