Industry Applications and Operational ROI

Turbine and Compressor Protection

In steam turbines and centrifugal compressors, shaft vibration must be measured with high accuracy to avoid contact between rotating and stationary parts. The 330101-00-11-20-02-00 provides a linear range of 2 mm (80 mils) with an incremental scale factor of 7.87 V/mm, enabling early detection of imbalance or misalignment. This reduces unplanned downtime and extends equipment life.

Pump Monitoring in Harsh Environments

For pumps handling high-temperature fluids, the standard probe temperature range of -52°C to +177°C ensures reliable operation even in demanding conditions. The PPS tip and stainless steel case resist corrosion and mechanical wear, delivering long service life.

Installation and Setup Guidance

When installing the 330101-00-11-20-02-00, ensure the probe tip is positioned within the linear range starting at approximately 0.25 mm (10 mils) from the target. The recommended gap setting for radial vibration is -9 Vdc, corresponding to roughly 1.27 mm (50 mils). Field wiring should use 3-conductor shielded triad cable with 0.2 to 1.5 mm² (16 to 24 AWG) tinned conductors. Maximum field wiring length between the 3300 XL Proximitor Sensor and the monitor is 305 meters (1,000 feet).

Maintenance and Reliability

Inspect the probe cable and connector periodically for signs of wear or damage. The patented CableLoc design provides 330 N (75 lbf) pull strength, enhancing cable retention. Avoid exposing the probe to temperatures below -34°C (-30°F) to prevent premature failure of the pressure seal. The probe is designed to seal differential pressure between the tip and case using a Viton® O-ring.

Robust Vibration Sensing for Critical Machinery

Industrial rotating machinery demands precise, reliable vibration monitoring to prevent catastrophic failures. The Bently Nevada 330101-00-11-20-02-00 3300 XL 8 mm Probe delivers the accuracy and durability required for continuous protection of turbines, compressors, and pumps. This probe features a 3/8-24 UNF thread design without armor, making it suitable for standard mounting configurations where space is constrained.

Compatibility and Integration

This 3300 XL 8 mm probe is compatible with Bently Nevada 3300 XL extension cables and Proximitor sensors. The miniature coaxial ClickLoc connector ensures secure, quick connections. For systems requiring extended temperature range, optional ETR probes are available for tip temperatures up to +218°C and cable temperatures up to +260°C.

Selection Guide and Purchasing Advice

When selecting a replacement or new probe, verify the thread type (3/8-24 UNF), overall length (2.0 meters), and connector style (miniature coaxial ClickLoc).
