Industry Applications
Its 2 mm linear range and 7.87 V/mm sensitivity enable precise shaft displacement monitoring, helping operators detect early signs of bearing wear or imbalance. The rugged PPS tip and stainless steel case withstand harsh industrial conditions, reducing unplanned downtime.
Installation & Setup Guidance
When installing the 330101-00-72-20-02-CN, ensure proper thread engagement (max 0.563 in) and use the recommended torque of 11.2 N•m (100 in•lbf) for forward mounted probes. The probe should be positioned to achieve a -9 Vdc gap setting for radial vibration measurements. Field wiring must 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 monitor.
Maintenance & Reliability
Inspect the probe and cable periodically for physical damage, especially in high-temperature or high-humidity environments. The probe is designed to seal differential pressure with a Viton® O-ring; avoid exposing the probe to temperatures below –34°C (–30°F) to prevent premature pressure seal failure. The probe's relative humidity tolerance ensures less than 3% change in Average Scale Factor (ASF) after 56 days at 93% humidity per IEC 68-2-3.
Robust Vibration Sensing for Critical Machinery
The Bently Nevada 330101-00-72-20-02-CN is a 3300 XL 8 mm probe designed for reliable eddy-current displacement measurement. This model features a 3/8-24 UNF thread, a 2.0 meter cable, and a Miniature coaxial ClickLoc connector. Its robust construction, including a patented TipLoc molding and CableLoc design, provides enhanced durability and pull strength of 330 N (75 lbf).
Compatibility & Integration
The 330101-00-72-20-02-CN is compatible with Bently Nevada 3300 XL Proximitor Sensors and monitoring systems. The Miniature coaxial ClickLoc connector simplifies cable attachment and removal. For extended temperature ranges, the probe tip can operate up to +218°C (+425°F) with the ETR option.
Selection Guide & Purchasing Advice
When selecting a replacement or new probe, verify the thread size (3/8-24 UNF), cable length (2.0 meters), and connector type.
