Bently Nevada 330101-00-08-10-02-05 3300 XL 8 mm Probe, 3/8-24 UNF Thread, Without Armor

Technical Specifications Breakdown

Key parameters for the 330101-00-08-10-02-05 are listed below for quick reference:

Common Applications in Industrial Plants

Steam and Gas Turbines: Mount the probe near bearing housings to monitor shaft radial vibration. The -9 Vdc recommended gap setting provides optimal sensitivity within the linear range.

Centrifugal Compressors: Use the 3300 XL 8 mm probe to detect thrust position changes that indicate impending failure. The stainless steel case withstands oil and moisture exposure common in compressor trains.

Pumps and Fans: Install the probe through a 3/8-24 UNF threaded hole for secure mounting. The PPS tip resists chemical attack from process fluids.

Installation Guidance for Engineers

When positioning the probe, ensure the target surface is clean and free of electrical discontinuities. Use the recommended field wiring of 0.2 to 1.5 mm² (16 to 24 AWG) three-conductor shielded triad cable. Maximum cable length between the Proximitor Sensor and monitor is 305 meters (1,000 feet). For radial vibration measurements, set the initial gap to -9 Vdc (approximately 1.27 mm or 50 mils). Verify the gap voltage using a digital multimeter before securing the probe.

Maintenance and Reliability Considerations

Inspect the probe cable and connector periodically for signs of wear or damage. The probe's Viton O-ring seals differential pressure between tip and case, but probes are not pressure tested before shipment. Avoid exposing the probe to temperatures below –34°C (–30°F) to prevent premature failure of the pressure seal. The probe operates reliably in up to 93% relative humidity with less than 3% change in Average Scale Factor.

Reliable Vibration Sensing for Critical Machinery

When rotating machinery experiences unexpected vibration, unplanned downtime and costly repairs follow. The Bently Nevada 330101-00-08-10-02-05 3300 XL 8 mm Probe provides precise, non-contact displacement measurement to detect shaft vibration and position changes early. Designed for harsh industrial environments, this probe helps engineers implement predictive maintenance strategies that reduce operational risk.

Preventing Failure Through Accurate Measurement

Mechanical looseness, bearing wear, and imbalance generate distinct vibration signatures. The 330101-00-08-10-02-05 probe's 2 mm linear range and 7.87 V/mm scale factor deliver the resolution needed to distinguish these fault patterns. Its patented TipLoc molding method creates a robust bond between probe tip and body, reducing signal drift over time. The CableLoc design provides 330 N (75 lbf) pull strength, ensuring cable integrity even in high-vibration installations.

Compatibility and System Integration

This probe is part of the Bently Nevada 3300 XL system and works with compatible Proximitor sensors and monitors. The miniature coaxial ClickLoc connector simplifies field installation and reduces signal noise. Agency approvals include CSA, ATEX, and IECEx for use in hazardous locations.

Selection Guide and Purchasing Advice

Choose the 330101-00-08-10-02-05 when you need a 1.0 meter probe with standard cable and agency approvals. For longer cable lengths or armored versions, contact AutoDCSTech for alternative options. Please verify current lifecycle status and availability with AutoDCSTech before ordering.
