Bently Nevada 3300 XL 8 mm Proximity Probe 330102-00-35-05-02-05

Technical Specifications Breakdown

Key parameters for the 330102-00-35-05-02-05 are listed below for quick reference:

Industry Applications for Vibration Monitoring

The 2 mm linear range (0.25 to 2.3 mm from target) provides precise measurement for early fault detection. In petrochemical plants, the ATEX and IECEx approvals allow installation in Zone 0 and Zone 2 hazardous areas. The probe's robust construction—PPS tip and stainless steel case—resists harsh process fluids and temperatures up to 177°C (standard). By catching misalignment or bearing wear early, you avoid unplanned downtime and costly repairs.

Installation and Setup Guidance

Proper installation is critical for accurate readings. Use 3-conductor shielded triad cable with tinned field wiring (0.2 to 1.5 mm² / 16 to 24 AWG). The maximum field wiring length between the probe and monitor is 305 meters (1,000 feet). For radial vibration, set the gap to -9 Vdc (approximately 1.27 mm or 50 mils). Ensure the probe tip is clean and the target surface is smooth. Thread engagement must not exceed 0.563 inches. The miniature coaxial ClickLoc connector simplifies field connection—just click and lock.

Maintenance and Reliability

Inspect the probe and cable periodically for physical damage or corrosion. The probe is designed to seal differential pressure between tip and case using a Viton® O-ring, but it is not pressure tested before shipment. Avoid exposing the probe to temperatures below -34°C (-30°F) to prevent premature pressure seal failure. The probe's relative humidity performance shows less than 3% change in Average Scale Factor (ASF) after 56 days at 93% humidity per IEC 68-2-3.

Understanding the 3300 XL 8 mm Proximity Probe

When monitoring shaft vibration and position in rotating machinery, accurate and reliable measurement is non-negotiable. The Bently Nevada 330102-00-35-05-02-05, a 3300 XL 8 mm Proximity Probe, delivers the precision needed for critical applications. This probe features a 3/8-24 UNF thread with armor, a 0.5 meter (1.6 feet) cable, and a miniature coaxial ClickLoc connector. It carries CSA, ATEX, and IECEx approvals, making it suitable for hazardous environments. The probe tip is made of polyphenylene sulfide (PPS), and the case is AISI 303 or 304 stainless steel (SST).

Compatibility and Integration

This probe works with Bently Nevada 3300 XL Proximitor Sensors and monitoring systems. For intrinsically safe installations, use zener barriers per drawing 141092 or galvanic isolators. For non-incendive circuits, follow drawing 140979. The probe is compatible with Class I, Zone 0 and Zone 2 environments as specified in the temperature schedules.

Selection Guide and Purchasing Advice

When selecting a replacement or new probe, verify the thread size (3/8-24 UNF), overall case length (3.5 in), and total length (0.5 m). The 330102-00-35-05-02-05 includes armor and agency approvals. For applications requiring extended temperature range (tip to 218°C, cable to 260°C), consider the extended range variant.
