Bently Nevada 330102-00-20-10-02-CN 3300 XL 8 mm Proximity Probe

Product Overview

The Bently Nevada 330102-00-20-10-02-CN is a 3300 XL 8 mm proximity probe designed for non-contact displacement measurement. It features a polyphenylene sulfide (PPS) probe tip and a case made from AISI 303 or 304 stainless steel. This probe includes a miniature coaxial ClickLoc connector with standard cable, and its total length is 1.0 meter (3.3 feet). The unthreaded length option is 0 inches, and the overall case length is 2 inches. The agency approval option is Country Specific Approval (CN).

Technical Specifications Breakdown

Key parameters for the 330102-00-20-10-02-CN are listed below for quick reference:

Industry Applications

The PPS tip resists chemical attack, while the stainless steel case withstands corrosive atmospheres common in refining processes.

Installation & Setup Guidance

Mount the probe using the 3/8-24 UNF thread, ensuring thread engagement does not exceed 0.563 inches. Use 3-conductor shielded triad cable with tinned field wiring, sized between 0.2 to 1.5 mm² (16 to 24 AWG). The maximum field wiring length between the 3300 XL Proximitor Sensor and the monitor is 305 meters (1,000 feet). For radial vibration applications, set the initial gap to -9 Vdc, corresponding to approximately 1.27 mm (50 mils) from the target. Verify linear range operation from 0.25 to 2.3 mm (10 to 90 mils).

Maintenance & Reliability

Inspect the probe cable and connector periodically for signs of wear or corrosion. 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; it is not pressure tested before shipment. For applications requiring pressure seal verification, contact the custom design department.

The Evolution of Precision Monitoring

Industrial machinery has grown more complex over the decades, demanding sensors that keep pace with tighter tolerances and harsher environments. The Bently Nevada 3300 XL series represents a leap forward in proximity probe design, offering engineers a robust tool for radial vibration and position measurement. The 330102-00-20-10-02-CN model embodies this evolution, combining proven eddy-current technology with materials engineered for longevity.

Compatibility & Integration

This probe is designed for use with Bently Nevada 3300 XL Proximitor sensors. The 1.0 meter cable length is compatible with standard monitoring systems. For 3-meter or 5-meter configurations, refer to the 330101 probe or specific Proximitor sensor requirements. The probe can be installed with intrinsically safe zener barriers per drawing 141092 or galvanic isolators for hazardous area use.

Selection Guide & Purchasing Advice

When selecting a replacement or new installation, verify the required cable length, thread type, and agency approvals. The 330102-00-20-10-02-CN is available from AutoDCSTech, your trusted source for industrial automation parts. Please verify current lifecycle status and availability with AutoDCSTech before ordering.

Troubleshooting & Common Issues

If readings are erratic, check the cable continuity and connector integrity. Ensure the target material is compatible with the probe's eddy-current principle. Verify that the gap is within the linear range (0.25 to 2.3 mm). If the probe has been exposed to extreme temperatures, inspect the pressure seal for signs of leakage. For persistent issues, consult the Bently Nevada installation manual.
