Bently Nevada 330104-01-05-50-02-02 3300 XL 8 mm Proximity Probe

Product Overview

When critical rotating machinery requires precise and reliable displacement measurement, the Bently Nevada 330104-01-05-50-02-02 3300 XL 8 mm Proximity Probe delivers accurate performance. This probe is part of the proven 3300 XL series, designed for non-contact vibration and position monitoring in harsh industrial environments. With a robust construction featuring a polyphenylene sulfide (PPS) probe tip and AISI 303 or 304 stainless steel case, it withstands demanding conditions while providing consistent readings.

Technical Specifications Breakdown

The 330104-01-05-50-02-02 offers a total length of 5.0 meters (16.4 feet), optimized for use with the 5 meter Proximitor sensor. Key parameters include:

Unthreaded length: 10 mm (option 01)

Overall case length: 50 mm (option 05)

Connector: Miniature coaxial ClickLoc connector with standard cable (option 02)

Probe DC resistance (RPROBE): 8.73 ± 0.50 Ω at 5.0 m length

Thread: M10 x 1, with armor for enhanced durability

These specifications ensure compatibility with the 3300 XL system components, maintaining system accuracy and interchangeability when calibrated to the AISI 4140 steel target.

Industry Applications

This proximity probe excels in monitoring radial vibration and axial position of turbines, compressors, pumps, and other rotating equipment. In petrochemical plants, the 330104-01-05-50-02-02 provides early warning of shaft misalignment or bearing wear, reducing unplanned downtime. For power generation, its high-temperature rating (up to +232°C for T1 classification) allows reliable operation near steam turbines and generators.

Installation & Setup Guidance

Proper installation is critical for accurate measurements. Mount the probe with a 1.27 mm (50 mils) gap to the target using the recommended AISI 4140 steel target for calibration. Ensure the M10 x 1 thread is securely engaged and the armored cable is routed to avoid sharp bends. The 5.0 m cable length is designed exclusively for the 5 meter Proximitor sensor—do not use extension cables without verifying compatibility. For hazardous locations, follow drawing 140979 for non-incendive circuits or drawing 141092 for intrinsically safe barriers.

Maintenance & Reliability

Regularly inspect the probe tip and cable for physical damage or contamination. The Viton O-ring seal maintains differential pressure integrity between the tip and case, so check for signs of leakage. In environments with extreme temperatures, refer to the temperature schedule: for EPL Ga and Gc, the probe operates from -55°C to +232°C (T1) down to -55°C to +40°C (T5). Periodic verification of the DC resistance (8.73 ± 0.50 Ω) helps confirm cable integrity.

Compatibility & Integration

The 330104-01-05-50-02-02 integrates seamlessly with 3300 XL 8 mm Proximitor Sensors and extension cables. It accepts 3300-series 5 mm and 8 mm probes. Power requirements range from -17.5 Vdc to -26 Vdc with a maximum consumption of 12 mA. For hazardous area installations, it supports Class I, Zone 0 (AEx/Ex ia IIC T5...T1 Ga) and Class I, Zone 2 (AEx/Ex nA IIC T5...T1 Gc) approvals. Always verify the agency approval option (00 = not required) matches your site's certification needs.

Selection Guide & Purchasing Advice
