Bently Nevada 330101-02-12-10-02-00 3300 XL 8 mm Probe, 3/8-24 UNF Thread

Technical Specifications Breakdown

Key parameters for the 330101-02-12-10-02-00 are listed below for quick reference:

Industry Applications for Reliable Vibration Monitoring

The thicker PPS encapsulation of the probe coil and larger diameter body provide superior ruggedness compared to smaller probes. Typical applications include monitoring radial vibration and axial position in steam turbines, compressors, pumps, and large electric motors. The patented TipLoc and CableLoc designs ensure a robust bond and high pull strength (330 N / 75 lbf), reducing the risk of failure in high-vibration environments.

Installation and Setup Guidance

Proper installation is critical for accurate measurements. The 330101-02-12-10-12-00 probe uses a 3/8-24 UNF thread. For standard forward mounted probes, the recommended probe case torque is 11.2 N·m (100 in·lbf), with a maximum rated torque of 33.9 N·m (300 in·lbf). For the first three threads, use a recommended torque of 7.5 N·m (66 in·lbf) and a maximum of 22.6 N·m (200 in·lbf). 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.

Maintenance and Reliability

Regularly inspect the probe and cable for physical damage, especially near the tip and connector. The probe is designed to seal differential pressure between the tip and case using a Viton® O-ring. Avoid exposing the probe to temperatures below -34°C (-30°F) to prevent premature failure of the pressure seal. The probe case material is AISI 303 or 304 stainless steel, offering good corrosion resistance in most industrial environments.

The Evolution of Precision: Bently Nevada 3300 XL 8 mm Probe

Industrial rotating machinery has grown more demanding, and vibration monitoring technology has evolved to match. The Bently Nevada 330101-02-12-10-02-00 represents a significant step forward in eddy-current probe design, offering enhanced robustness and measurement accuracy for critical asset protection. This 3300 XL 8 mm probe is engineered for applications where reliability and repeatable data are paramount.

Compatibility and Integration

The 3300 XL 8 mm probe is designed for use with Bently Nevada 3300 XL extension cables and Proximitor sensors. The miniature coaxial ClickLoc connector provides a secure, quick-connect interface. For optimal performance, use the recommended extension cable with a capacitance of 69.9 pF/m (21.3 pF/ft) typical. The system provides a linear range of 2 mm (80 mils), beginning at approximately 0.25 mm (10 mils) from the target.

Selection Guide and Purchasing Advice

When selecting a replacement or new probe, verify the thread type and cable length. The 330101-02-12-10-02-00 is a 1.0 meter probe with a 3/8-24 UNF thread and miniature coaxial ClickLoc connector. For applications requiring higher temperature tolerance, consider the extended temperature range option. Please verify current lifecycle status and availability with AutoDCSTech before ordering.
