Bently Nevada 330102-30-65-10-02-CN 3300 XL 8 mm Proximity Probe

Technical Specifications Breakdown

Key parameters for the 330102-30-65-10-02-CN are listed below for quick reference:

Installation Guidance for Optimal Performance

Proper installation is key to accurate readings. The probe features a 3/8-24 UNF thread with a maximum thread engagement of 0.563 in. Field wiring should use 0.2 to 1.5 mm² (16 to 24 AWG) three-conductor shielded triad cable with tinned ends. Maximum cable length between the 3300 XL Proximitor Sensor and monitor is 305 meters (1,000 feet). For best frequency response, keep field wiring as short as possible. The probe is designed to seal differential pressure between tip and case using a Viton O-ring; contact the custom design department if pressure testing is required.

Ensuring Machinery Reliability with Precision Measurement

In rotating machinery, undetected shaft vibration can lead to catastrophic failure. The Bently Nevada 330102-30-65-10-02-CN 3300 XL 8 mm Proximity Probe provides accurate, non-contact displacement measurement to protect your critical assets. This probe is engineered for harsh industrial environments, offering a linear range of 2 mm (80 mils) from 0.25 to 2.3 mm (10 to 90 mils) with a recommended gap setting of -9 Vdc for radial vibration applications.

Maintenance and Reliability

Routine inspection of the probe cable and connector ensures long service life. The probe operates reliably in up to 93% relative humidity with less than 3% change in Average Scale Factor (ASF) after 56 days per IEC 68-2-3. Avoid exposing the probe to temperatures below -34°C (-30°F) to prevent premature pressure seal failure. The stainless steel case resists corrosion in most industrial environments.

Solving Vibration Monitoring Challenges

Traditional contact sensors wear out and introduce measurement errors. This proximity probe uses eddy current technology to sense shaft position without physical contact, eliminating mechanical wear. Its PPS tip withstands high temperatures up to +177°C standard, or +218°C for the tip in extended range models, ensuring reliable operation in demanding applications.

Compatibility and System Integration

This probe is designed for use with Bently Nevada 3300 XL Proximitor sensors. For 1.0 meter probes, use the corresponding Proximitor sensor (5-meter probes require a 5 m Proximitor; 3-meter probes require a 9 m Proximitor). The miniature coaxial ClickLoc connector simplifies field replacement and ensures secure signal transmission. For intrinsically safe installations, use approved zener barriers per drawing 141092 or galvanic isolators for Class I, Zone 0 applications.

Selection and Purchasing Advice

When selecting a replacement probe, verify the total length, thread type, and connector. The 330102-30-65-10-02-CN is a 1.0 meter probe with 3/8-24 UNF threads and a ClickLoc connector.
