Technical Specifications Breakdown

Key parameters for the 330101-00-30-20-12-05 are listed below for quick reference:

Industry Applications for the 3300 XL Probe

The 8 mm diameter provides a thicker PPS encapsulation, offering superior resistance to physical abuse compared to smaller probes. The FluidLoc cable option prevents oil leakage through the cable interior, making it especially suitable for lubricated machinery where fluid ingress is a concern.

Installation and Setup Guidance

When installing the 330101-00-30-20-12-05, ensure the probe tip is properly gapped for radial vibration measurement. The recommended gap setting 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 (1000 feet) between the Proximitor Sensor and the monitor. The miniature coaxial ClickLoc connector simplifies cable attachment while maintaining signal integrity.

Maintenance and Reliability

The patented TipLoc molding method provides a robust bond between the probe tip and body, while the CableLoc design delivers 330 N (75 lbf) pull strength. These features reduce the risk of mechanical failure in high-vibration environments. The probe is designed to seal differential pressure between the tip and case using a Viton O-ring. For applications requiring pressure seal testing, contact the custom design department. The probe's relative humidity performance shows less than 3% change in Average Scale Factor when tested at 93% humidity per IEC 68-2-3 for up to 56 days.

The Challenge of Reliable Vibration Monitoring in Harsh Conditions

In rotating machinery, undetected shaft vibration can lead to catastrophic failure, unplanned downtime, and costly repairs. Engineers need a sensor that delivers consistent, accurate data even in extreme temperatures, high humidity, and physically demanding environments. The Bently Nevada 330101-00-30-20-12-05 3300 XL 8 mm Probe is engineered to meet these demands, providing a robust, field-proven solution for critical asset protection.

Compatibility and Integration

This probe is part of the 3300 XL system and is compatible with standard 3300 XL Proximitor Sensors and extension cables. The 2.0-meter total length allows flexible routing in tight installations. The CSA, ATEX, and IECEx approvals enable use in hazardous locations, expanding its applicability across oil and gas, chemical, and power generation industries.

Selection Guide and Purchasing Advice

When selecting a replacement or new probe, verify the thread size (3/8-24 UNF), overall case length (3.0 in), and total cable length (2.0 m).
