Bently Nevada 330101-10-27-05-02-00 3300 XL 8 mm Probe, 3/8-24 UNF Thread

Product Overview

The Bently Nevada 330101-10-27-05-02-00 is a 3300 XL 8 mm probe with 3/8-24 UNF thread, without armor. This component is engineered for precise vibration measurement in rotating machinery. Its patented TipLoc molding method ensures a robust bond between the probe tip and body, while the CableLoc design provides 330 N (75 lbf) pull strength for secure cable attachment. The miniature coaxial ClickLoc connector simplifies installation and maintenance.

Technical Specifications Breakdown

Key parameters for the 330101-10-27-05-02-00 are listed below for quick reference:

Industry Applications

The thicker encapsulation of the probe coil in molded PPS plastic results in a more rugged probe, making it suitable for harsh industrial environments. The larger diameter probe body provides a stronger, more robust case, reducing the risk of physical damage during operation. Engineers often choose this model when optimal robustness against physical abuse is required.

Installation & Setup Guidance

When installing the 330101-10-27-05-02-00, follow standard proximity probe mounting procedures. Ensure the probe is securely fastened using the 3/8-24 UNF thread. The recommended probe case torque for standard forward mounted probes is 11.2 N·m (100 in·lbf), with a maximum rated torque of 33.9 N·m (300 in·lbf). For the first three threads, use a recommended torque of 7.5 N·m (66 in·lbf) and a maximum of 22.6 N·m (200 in·lbf). The miniature coaxial ClickLoc connector simplifies cable attachment. Field wiring should use 0.2 to 1.5 mm² (16 to 24 AWG) three-conductor shielded triad cable with tinned wiring, with a maximum length of 305 meters (1,000 feet) between the Proximitor Sensor and the monitor.

Maintenance & Reliability

The probe's robust design, including the patented TipLoc and CableLoc features, minimizes maintenance needs. The probe is designed to seal differential pressure between the probe tip and case using a Viton O-ring. For optimal performance, inspect the probe and cable periodically for physical damage. The probe operates reliably within a standard temperature range of -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 material (AISI 303 or 304 SST) offers corrosion resistance.

Compatibility & Integration

This probe is part of the 3300 XL system and is compatible with 3300 XL extension cables and Proximitor Sensors. The system provides an Incremental Scale Factor (ISF) of 7.87 V/mm (200 mV/mil) ± 5% for standard 5 or 1 meter systems, including interchangeability error. For standard 9 meter systems, the ISF is 7.87 V/mm (200 mV/mil) ± 6.5%. The Deviation from Best Fit Straight Line (DSL) for standard 5 or 1 meter systems is less than ±0.025 mm (±1 mil) at 0°C to +45°C. Ensure the Proximitor Sensor and monitor are compatible with the 8 mm probe for accurate measurements.

Selection Guide & Purchasing Advice

When selecting a vibration probe, consider the specific requirements of your application, including temperature range, cable length, and connector type. The 330101-10-27-05-02-00 offers a 0.5 meter cable with a miniature coaxial ClickLoc connector, making it suitable for installations where space is limited. For applications requiring extended temperature range or armored cable, consult the Bently Nevada product line. AutoDCSTech stocks this model and can provide availability and lifecycle status. Please verify current lifecycle status and availability with AutoDCSTech before ordering.

Troubleshooting & Common Issues

If the probe fails to provide accurate readings, first check the cable connections and ensure the ClickLoc connector is fully seated. Verify that the probe gap is set to the recommended -9 Vdc (approximately 1.27 mm or 50 mils) for radial vibration. Inspect the probe tip for physical damage or contamination. If the probe is exposed to temperatures outside the standard range, consider using an extended temperature range probe. For persistent issues, consult the Bently Nevada documentation or contact AutoDCSTech for support.
