Bently Nevada 330101-00-90-05-02-CN 3300 XL 8 mm Probe

Over the past decades, industrial machinery monitoring has evolved from basic manual inspections to sophisticated, continuous online systems. The Bently Nevada 330101-00-90-05-02-CN 3300 XL 8 mm Probe represents a key advancement in this evolution, offering enhanced robustness and accuracy for critical rotating equipment. This probe is designed for permanent installation in applications such as steam turbines, compressors, and pumps, where precise shaft vibration and position measurements are essential for predictive maintenance and asset protection.

Technical Specifications Breakdown

Key parameters for the 330101-00-90-05-02-CN are listed below for quick reference:

Industry Applications

In steam turbines, the 330101-00-90-05-02-CN provides accurate shaft displacement readings, enabling early detection of imbalance or misalignment. For centrifugal compressors, its robust PPS tip and stainless steel case withstand harsh conditions while maintaining a linear range of 2 mm (80 mils). The probe's patented TipLoc and CableLoc designs offer superior pull strength (330 N / 75 lbf), reducing downtime from cable failures in high-vibration applications.

Installation and Setup Guidance

Proper installation is vital for accurate measurements. The 330101-00-90-05-02-CN uses a 3/8-24 UNF thread for mounting. Ensure the probe tip is clean and free of debris before insertion. 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. Always verify the target material and surface finish per Bently Nevada guidelines.

Maintenance and Reliability

Periodic inspection of the probe cable and connector is recommended to ensure no damage or wear. The probe's Viton® O-ring seals differential pressure, but probes are not pressure tested prior to shipment. Avoid exposing the probe to temperatures below -34°C (-30°F) to prevent premature pressure seal failure. For extended temperature range applications, the probe tip can operate up to +218°C (+425°F), with cable and connector rated to +260°C (+500°F).

Compatibility and Integration

This probe is part of the 3300 XL system and is compatible with Bently Nevada Proximitor Sensors and monitors. The miniature coaxial ClickLoc connector ensures secure and quick cable attachment. The standard cable length of 0.5 meter (1.6 feet) allows flexible routing within machinery. For longer runs, extension cables with matched capacitance (69.9 pF/m typical) maintain signal integrity.

Selection Guide and Purchasing Advice

When selecting a replacement or new probe, verify the thread size (3/8-24 UNF), overall case length (9.0 in), and total length (0.5 meter).
