Product Overview

The 330102-00-96-05-02-05 is a 3300 XL 8 mm Proximity Probe from Bently Nevada, a trusted brand in industrial monitoring. It features a 3/8-24 UNF thread with armor, a 0.5 meter (1.6 feet) total length, and a miniature coaxial ClickLoc connector with standard cable. The probe tip is made of polyphenylene sulfide (PPS), and the case is AISI 303 or 304 stainless steel (SST). Agency approvals include CSA, ATEX, and IECEx, making it suitable for hazardous area installations.

Technical Specifications Breakdown

Key parameters for the 330102-00-96-05-02-05 are listed below for quick reference:

Industry Applications

Steam Turbine Radial Vibration Monitoring

In steam turbine installations, the probe is mounted near bearing housings to measure shaft radial vibration. The 2 mm linear range and -9 Vdc recommended gap setting provide accurate data for trend analysis and alarm thresholds. The probe's stainless steel case and PPS tip resist high temperatures and moisture, ensuring long-term stability.

Compressor Axial Position Measurement

For centrifugal compressors, the probe monitors thrust bearing wear by measuring axial shaft position. The 0.5 meter cable with ClickLoc connector simplifies installation in confined spaces. The CSA, ATEX, and IECEx approvals allow use in hazardous gas environments (Class I, Zone 0).

Installation & Setup Guidance

When installing the probe, ensure the thread engagement does not exceed 0.563 inches for the 3/8-24 UNF thread. Use field wiring of 0.2 to 1.5 mm² (16 to 24 AWG) with a 3-conductor shielded triad cable, tinned ends, and a maximum length of 305 meters (1,000 feet) to the Proximitor Sensor. The probe is not pressure tested before shipment; contact the custom design department if pressure seal testing is required.

Maintenance & Reliability

The probe's design includes a Viton O-ring for sealing differential pressure between tip and case. Exposing the probe to temperatures below -34°C (-30°F) may cause premature failure of the pressure seal. Inspect the probe and cable periodically for physical damage, especially in high-vibration or corrosive environments. The probe's relative humidity performance shows less than 3% change in Average Scale Factor (ASF) after 56 days at 93% humidity.

Solving Vibration Monitoring Challenges in Rotating Machinery

In critical rotating machinery such as steam turbines, compressors, and large pumps, undetected shaft vibration can lead to catastrophic failure and unplanned downtime. The Bently Nevada 330102-00-96-05-02-05 3300 XL 8 mm Proximity Probe provides precise, non-contact measurement of radial vibration and axial position, enabling early detection of mechanical issues. This robust probe is designed for continuous operation in demanding environments, offering reliable data for predictive maintenance and asset protection.

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. For intrinsically safe installations, use zener barriers per drawing 141092 or galvanic isolators. For non-incendive circuits, follow drawing 140979.

Selection Guide & Purchasing Advice

When selecting a replacement or new probe, verify the thread size, cable length, and connector type match your application. The 330102-00-96-05-02-05 is a standard configuration with 0.5 meter cable and ClickLoc connector. For other options, consult the Bently Nevada 3300 XL series documentation.
