Bently Nevada 330101-00-12-05-02-CN 3300 XL 8 mm Probe, 3/8-24 UNF Thread, Without Armor

Technical Specifications Breakdown

Key parameters for the 330101-00-12-05-02-CN are listed below for quick reference:

Industry Applications

Steam Turbine and Compressor Monitoring

In high-speed rotating equipment, the 330101-00-12-05-02-CN provides reliable shaft vibration and position data. Its linear range of 2 mm (80 mils) and precise ISF of 7.87 V/mm ensure accurate trend analysis for predictive maintenance programs.

Pump and Motor Protection

For pumps and motors operating in harsh environments, the probe's stainless steel case and PPS tip resist corrosion and mechanical stress. The patented TipLoc molding method creates a robust bond between tip and body, reducing false readings from vibration or thermal cycling.

Cost-Benefit and Operational ROI (Angle C)

Investing in the 3300 XL 8 mm probe reduces unplanned downtime by providing early warning of shaft misalignment or bearing wear. The thicker encapsulation and CableLoc design (330 N pull strength) extend service life, lowering total cost of ownership compared to standard probes.

Installation and Setup Guidance

Mount the probe using the 3/8-24 UNF thread into a suitable mounting block or bracket. Ensure the target surface is clean and within the linear range (0.25 to 2.3 mm from target). For radial vibration applications, set the initial gap to achieve approximately -9 Vdc output. Use field wiring of 0.2 to 1.5 mm² (16 to 24 AWG) with a three-conductor shielded triad cable. Maximum field wiring length between the Proximitor sensor and monitor is 305 meters (1,000 feet).

Maintenance and Reliability

Periodically inspect the probe cable and connector for signs of wear or damage. Avoid exposing the probe to temperatures below -34°C (-30°F) to prevent premature failure of the pressure seal. The probe is designed to seal differential pressure between tip and case using a Viton O-ring; if your application requires pressure testing, contact the custom design department.

Compatibility and Integration

This probe is part of the 3300 XL system and is compatible with Bently Nevada extension cables and Proximitor sensors. The miniature coaxial ClickLoc connector ensures secure, quick connections. For systems requiring fluid sealing, optional FluidLoc cable options are available to prevent oil leakage through the cable interior.

Selection Guide and Purchasing Advice

When selecting a replacement or new probe, verify the thread size (3/8-24 UNF), cable length (0.5 meter), and connector type (miniature coaxial ClickLoc). The 330101-00-12-05-02-CN is available from AutoDCSTech, your trusted source for industrial automation parts. Please verify current lifecycle status and availability with AutoDCSTech before ordering.

Troubleshooting and Common Issues

If output readings drift or become erratic, check the probe tip for contamination or physical damage. Verify that the gap is within the linear range and that the cable is not kinked or stressed. For signal noise issues, ensure field wiring is properly shielded and grounded. If problems persist, consult the Bently Nevada system manual for detailed diagnostics.
