Bently Nevada 330101-00-50-10-02-00 3300 XL 8 mm Probe

Product Overview

The Bently Nevada 330101-00-50-10-02-00 is a 3300 XL 8 mm probe with a 3/8-24 UNF thread, designed without armor for direct installation in industrial machinery. This probe is part of the 3300 XL series, known for its robust construction and precise vibration measurement. The probe's cable incorporates a patented CableLoc design that offers 330 N (75 lbf) pull strength, ensuring secure attachment.

Technical Specifications Breakdown

Key parameters for the 330101-00-50-10-02-00 are listed below for quick reference:

Industry Applications

This probe is engineered for continuous vibration monitoring in critical rotating machinery such as turbines, compressors, and pumps. The 8 mm probe design provides a thicker encapsulation of the probe coil in molded PPS plastic, resulting in a more rugged probe that withstands physical abuse. The larger diameter of the probe body also offers a stronger, more robust case. For applications where oil or other liquids might leak through the cable interior, the optional FluidLoc cable option prevents such leakage, enhancing reliability in harsh environments.

Installation & Setup Guidance

When installing the 330101-00-50-10-02-00, ensure the probe tip is properly positioned relative to the target. The recommended gap setting for radial vibration is -9 Vdc, approximately 1.27 mm (50 mils). The linear range begins at approximately 0.25 mm (10 mils) from the target and extends from 0.25 to 2.3 mm (10 to 90 mils). Use field wiring of 0.2 to 1.5 mm² (16 to 24 AWG) with a 3-conductor shielded triad cable and tinned field wiring. The maximum length between the 3300 XL Proximitor Sensor and the monitor is 305 meters (1,000 feet). Refer to frequency response graphs for signal rolloff at high frequencies with longer wiring.

Maintenance & Reliability

Regular inspection of the probe and cable is recommended to ensure reliable operation. The probe is designed to seal differential pressure between the probe tip and case using a Viton O-ring. Exposing the probe to temperatures below -34°C (-30°F) may cause premature failure of the pressure seal. The probe operates reliably in high humidity environments, with less than a 3% change in Average Scale Factor (ASF) when tested in 93% humidity per IEC standard 68 2 3 for up to 56 days. For extended temperature range probes, the probe tip can withstand up to +218°C (+425°F), and the cable up to +260°C (+500°F).

Compatibility & Integration

The 330101-00-50-10-02-00 is compatible with the 3300 XL Proximitor Sensor system. The standard 5 or 1 meter system provides an Incremental Scale Factor (ISF) of 7.87 V/mm (200 mV/mil) ±5% over the 80 mil linear range from 0°C to +45°C (+32°F to +113°F). The standard 9 meter system offers ±6.5% interchangeability error. The Deviation from Best Fit Straight Line (DSL) for standard 5 or 1 meter systems is less than ±0.025 mm (±1 mil) over the same temperature range. This ensures accurate and repeatable vibration measurements.

Selection Guide & Purchasing Advice

When selecting the 330101-00-50-10-02-00, consider the specific thread requirement (3/8-24 UNF) and the absence of armor. This probe is suitable for applications where a compact, robust vibration sensor is needed. For assistance with lifecycle status or compatibility, contact AutoDCSTech.
