Bently Nevada 330101-00-09-15-12-CN 3300 XL 8 mm Probe, 3/8-24 UNF Thread

Overview

For maintenance engineers seeking a robust vibration sensing solution, the Bently Nevada 330101-00-09-15-12-CN offers proven reliability in monitoring rotating machinery. This 3300 XL 8 mm probe features a 3/8-24 UNF thread design without armor, making it suitable for direct installation in bearing housings and machine cases. The probe's patented TipLoc and CableLoc technologies enhance mechanical integrity, reducing the risk of sensor failure in demanding environments.

Technical Specifications Breakdown

Key parameters for the 330101-00-09-15-12-CN are listed below for quick reference:

Industry Applications

Its 2 mm linear range and high sensitivity (7.87 V/mm) allow early detection of shaft displacement, imbalance, and misalignment. Choosing this 8 mm design over smaller probes provides greater robustness against physical abuse, reducing unplanned downtime.

Installation & Setup Guidance

Mount the probe using the 3/8-24 UNF thread with recommended torque of 11.2 N·m (100 in·lbf) for standard forward mounting. For the first three threads, use 7.5 N·m (66 in·lbf). Set the recommended gap to -9 Vdc (approximately 1.27 mm or 50 mils) for radial vibration measurements. Ensure the target surface is clean and within the linear range (0.25 to 2.3 mm). Use 3-conductor shielded triad cable for field wiring, keeping total length under 305 meters to avoid signal roll-off.

Maintenance & Reliability

Inspect the probe and cable periodically for physical damage, especially at the connector and probe tip. The probe operates reliably from -52°C to +177°C (standard) and withstands up to 93% humidity with minimal scale factor change. The patented CableLoc design provides 330 N (75 lbf) pull strength, reducing cable detachment risks. Regularly verify the gap voltage and scale factor during scheduled outages.

Compatibility & Integration

This probe is designed for use with Bently Nevada 3300 XL Proximitor sensors and compatible monitoring systems. The miniature coaxial ClickLoc connector ensures secure, quick connections. The FluidLoc cable option prevents liquid ingress, maintaining signal integrity in oil-rich environments. Always pair with approved extension cables and monitors to preserve system accuracy.

Selection Guide & Purchasing Advice

When selecting a vibration probe, consider the machine's operating temperature, required linear range, and environmental exposure. The 330101-00-09-15-12-CN is a standard choice for most industrial rotating equipment. Contact AutoDCSTech to verify current lifecycle status and availability before ordering.
