Bently Nevada 330102-02-25-20-02-00 3300 XL 8 mm Proximity Probe

Technical Specifications Breakdown

Key parameters for the 330102-02-25-20-02-00 are listed below for quick reference:

Industry Applications

The PPS tip resists chemical attack and wear, extending service life in aggressive environments.

Installation & Setup Guidance

Mount the probe using the 3/8-24 UNF thread with a maximum thread engagement of 0.563 in. For field wiring, use 3-conductor shielded triad cable (0.2 to 1.5 mm² / 16 to 24 AWG) with tinned ends. Keep the cable length between the probe and the 3300 XL Proximitor Sensor under 305 meters (1,000 feet) to avoid signal roll-off at high frequencies. Set the initial gap to approximately -9 Vdc (1.27 mm) for radial vibration monitoring.

Maintenance & Reliability

Inspect the probe cable and connector periodically for damage or wear. Avoid exposing the probe to temperatures below -34°C (-30°F) to prevent premature pressure seal failure. The probe is designed to seal differential pressure between tip and case using a Viton® O-ring; however, it is not pressure tested before shipment. For applications requiring a pressure seal test, contact the custom design department.

Compatibility & Integration

When used with intrinsically safe zener barriers per drawing 141092 or galvanic isolators, it is approved for Class I, Zone 0 hazardous locations. For non-incendive installations, follow drawing 140979 for Class I, Zone 2 compliance.

Selection Guide & Purchasing Advice

When selecting a replacement probe, verify the thread size, cable length, and connector type match your existing system. The 330102-02-25-20-02-00 is a standard option with a 2.0 m cable and ClickLoc connector. For custom lengths or agency approvals, consult AutoDCSTech for availability and lead times. Please verify current lifecycle status and availability with AutoDCSTech before ordering.
