Bently Nevada 330101-20-35-10-02-CN 3300 XL 8 mm Probe without Armor

Technical Specifications Breakdown

Key parameters for the 330101-20-35-10-02-CN are listed below for quick reference:

Application in Turbomachinery and Compressors

The 2 mm linear range provides clear signals for early fault detection. With a recommended gap setting of -9 Vdc, operators can establish a consistent baseline for trend analysis. The 8 mm probe body offers enhanced ruggedness compared to smaller designs, reducing the risk of damage during installation or operation.

Installation Guidance for Optimal Performance

When installing the 330101-20-35-10-02-CN, ensure the target surface is clean and within the specified linear range. The probe uses a 3/8-24 UNF thread for secure mounting. 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 patented TipLoc and CableLoc designs provide 330 N (75 lbf) pull strength, enhancing cable retention and probe tip integrity.

Maintenance and Reliability Considerations

The probe operates reliably across a wide temperature range. Standard probes function from -52°C to +177°C (-62°F to +350°F). The stainless steel case and PPS tip resist corrosion and wear. For applications with high humidity, the probe shows less than a 3% change in Average Scale Factor when tested at 93% humidity per IEC 68-2-3. Regular inspection of the cable and connector is recommended to maintain signal integrity.

Reliable Vibration Sensing for Critical Machinery

Industrial rotating machinery faces constant stress from imbalance, misalignment, and bearing wear. Without accurate vibration monitoring, these issues escalate into unplanned downtime and costly repairs. The Bently Nevada 330101-20-35-10-02-CN 3300 XL 8 mm Probe offers a robust solution for continuous shaft vibration and position measurement. This non-contact eddy current probe is designed for demanding environments where precision and durability are non-negotiable.

Compatibility and System Integration

This probe is designed for use with Bently Nevada 3300 XL extension cables and Proximitor sensors. The miniature coaxial ClickLoc connector simplifies field installation and ensures a secure connection. The standard 1.0 meter system delivers an Incremental Scale Factor of 7.87 V/mm ± 5% over the linear range, with deviation from best fit straight line less than ±0.025 mm (±1 mil) at 0°C to +45°C. This consistency supports accurate vibration monitoring across multiple channels.
