Bently Nevada 330101-00-76-20-02-05 3300 XL 8 mm Probe, 3/8-24 UNF Thread, Without Armor

Robust Vibration Monitoring with the Bently Nevada 330101-00-76-20-02-05

For maintenance engineers seeking reliable machinery protection, the Bently Nevada 330101-00-76-20-02-05 3300 XL 8 mm probe delivers exceptional durability and precision.

Technical Specifications Breakdown

Key parameters for the 330101-00-76-20-02-05 are listed below for quick reference:

Industry Applications

This probe is engineered for continuous vibration monitoring on rotating machinery such as turbines, compressors, and pumps. The 8 mm diameter provides a thicker PPS encapsulation, offering superior robustness against physical abuse compared to smaller probes. Maintenance teams benefit from the patented TipLoc and CableLoc designs, which ensure a secure bond between tip and body and provide 330 N (75 lbf) pull strength, reducing the risk of cable failure in high-vibration environments.

Installation & Setup Guidance

When installing the 330101-00-76-20-02-05, ensure proper thread engagement: the maximum length of thread engagement for the 3/8-24 UNF thread is 0.563 in. For standard forward mounted probes, the recommended torque 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 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 a maximum length of 305 meters (1,000 feet) between the Proximitor Sensor and the monitor.

Maintenance & Reliability

The probe's stainless steel case and PPS tip resist corrosion and wear. Although the probe is not pressure tested before shipment, the Viton® O-ring seal is designed to handle differential pressure between tip and case. Exposing the probe to temperatures below –34˚C (-30˚F) may cause premature failure of the pressure seal, so avoid such conditions. The probe exhibits less than a 3% change in Average Scale Factor (ASF) when tested in 93% humidity per IEC standard 68-2-3 for up to 56 days, ensuring stable performance in humid environments.

Compatibility & 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 simplifies field installation and ensures a secure connection. For applications requiring oil leak prevention, optional FluidLoc cable options are available. Please verify current lifecycle status and availability with AutoDCSTech before ordering.

Selection Guide & Purchasing Advice

When selecting a replacement or new probe, consider the total length option: the 330101-00-76-20-02-05 includes a 2.0-meter cable. For longer runs, other options exist. AutoDCSTech stocks this exact model with CSA, ATEX, and IECEx approvals, ensuring compliance with global safety standards.
