Bently Nevada 330102-05-30-50-02-05 3300 XL 8 mm Proximity Probe

Technical Specifications Breakdown

Key parameters for the 330102-05-30-50-02-05 are listed below for quick reference:

Industry Applications

In petrochemical plants, the probe's CSA, ATEX, and IECEx approvals allow safe installation in hazardous areas, including Class I, Zone 0 environments when used with intrinsic safety barriers. The 5-meter cable length simplifies routing to the Proximitor sensor, reducing installation complexity. By providing early warning of shaft vibration or thrust position changes, the probe helps avoid unplanned downtime and costly repairs.

Installation & Setup Guidance

Mount the probe using the 3/8-24 UNF thread with a maximum thread engagement of 0.563 inches. Use 3-conductor shielded triad cable with tinned field wiring (0.2 to 1.5 mm² / 16 to 24 AWG) between the Proximitor sensor and monitor. The maximum field wiring length is 305 meters (1,000 feet). For radial vibration applications, set the initial gap to -9 Vdc (approximately 1.27 mm or 50 mils). Ensure the probe tip is clean and free of debris before installation.

Maintenance & Reliability

The probe's PPS tip and stainless steel case resist corrosion and wear. Operating temperature range for standard probes is -52°C to +177°C. Exposing the probe to temperatures below -34°C (-30°F) may cause premature failure of the pressure seal. Inspect the cable and connector periodically for damage. The probe sealing material is a Viton O-ring; probes are not pressure tested before shipment.

Precision Vibration Monitoring with the Bently Nevada 3300 XL Probe

Industrial rotating machinery demands precise, reliable monitoring to prevent catastrophic failures. The Bently Nevada 330102-05-30-50-02-05, part of the 3300 XL 8 mm Proximity Probe series, delivers accurate shaft vibration and position measurements even in the most demanding environments. Designed for use with the 5 meter Proximitor sensor, this probe offers a linear range of 2 mm (80 mils), starting at approximately 0.25 mm (10 mils) from the target. The recommended gap setting for radial vibration is -9 Vdc, corresponding to about 1.27 mm (50 mils).

Compatibility & Integration

This 5-meter probe is designed for use exclusively with the 5 meter Proximitor sensor. It is compatible with Bently Nevada monitoring systems that accept 3300 XL series inputs. For hazardous locations, follow the applicable installation drawings (e.g., 141092 for intrinsic safety, 140979 for non-incendive circuits).

Selection Guide & Purchasing Advice

When selecting a replacement or new probe, verify the total length, thread type, and approvals match your application. Please verify current lifecycle status and availability with AutoDCSTech before ordering.
