Bently Nevada 330101-00-25-20-12-05 3300 XL 8 mm Probe, 3/8-24 UNF Thread

Overview

For engineers tasked with safeguarding rotating machinery, the Bently Nevada 330101-00-25-20-12-05 offers a robust solution for precise vibration and position measurement. This 3300 XL 8 mm probe, featuring a 3/8-24 UNF thread and a 2.0-meter cable, is designed to withstand harsh industrial environments while delivering reliable data for predictive maintenance. Its patented TipLoc and CableLoc technologies enhance durability, reducing the risk of probe failure and unplanned downtime.

Technical Specifications Breakdown

Key parameters for the 330101-00-25-20-12-05 are listed below for quick reference:

Industry Applications

The 2 mm linear range and 7.87 V/mm sensitivity enable early detection of shaft vibration and displacement anomalies. With CSA, ATEX, and IECEx approvals, it is suitable for hazardous area installations where safety and reliability are paramount.

Installation & Setup Guidance

Proper installation is essential for accurate readings. Ensure the probe is mounted with the recommended torque of 11.2 N•m (100 in•lbf) for standard forward-mounted probes. The recommended gap setting for radial vibration is -9 Vdc, approximately 1.27 mm (50 mils). Use 3-conductor shielded triad cable for field wiring, with a maximum length of 305 meters (1,000 feet) between the Proximitor Sensor and the monitor. Verify thread engagement does not exceed 0.563 inches to avoid mechanical interference.

Maintenance & Reliability

The 3300 XL probe is built for longevity. The PPS tip and stainless steel case resist corrosion and mechanical stress. Inspect the probe and cable periodically for signs of wear or fluid ingress. The probe operates reliably in temperatures from -52°C to +177°C (standard) or up to +218°C for extended range versions. Avoid exposing the probe to temperatures below -34°C, as this may cause premature failure of the pressure seal.

Compatibility & Integration

This probe is designed for use with Bently Nevada 3300 XL Proximitor Sensors and monitoring systems. The miniature coaxial ClickLoc connector ensures a secure, quick connection. The 2.0-meter cable length is standard for many installations, but extension cables can be added to reach the Proximitor. Verify system compatibility before ordering.

Selection Guide & Purchasing Advice

When selecting a replacement or new probe, confirm the thread type (3/8-24 UNF), cable length, and connector style match your existing setup. The 330101-00-25-20-12-05 is a versatile choice for many industrial applications. Our team can help you verify specifications and ensure the correct part for your machinery.
