Product Overview
For critical rotating machinery, precise vibration measurement is non-negotiable. The Bently Nevada 330102-00-25-50-11-00 3300 XL 8 mm Proximity Probe delivers the accuracy and durability required for continuous monitoring in harsh industrial environments. Designed for use with the 5-meter Proximitor sensor, this probe provides a linear range of 2 mm (80 mils), starting at approximately 0.25 mm (10 mils) from the target. Its robust construction includes a polyphenylene sulfide (PPS) tip and an AISI 303 or 304 stainless steel case, ensuring long-term reliability.

Industry Applications
With a 2 mm linear range and a recommended gap setting of -9 Vdc, it provides precise data for predictive maintenance programs. The 5-meter cable length is specifically matched to the 5-meter Proximitor sensor, ensuring signal integrity. For applications requiring intrinsic safety, the probe can be installed with approved zener barriers or galvanic isolators for Class I, Zone 0 environments.

Installation & Setup Guidance
Mount the probe using the 3/8-24 UNF thread with a maximum thread engagement of 0.563 inches. Field wiring should use 0.2 to 1.5 mm² (16 to 24 AWG) three-conductor shielded triad cable, with a maximum length of 305 meters (1000 feet) between the Proximitor sensor and monitor. Ensure the target surface is clean and within the linear range. For radial vibration, set the initial gap to approximately -9 Vdc.
Maintenance & Reliability
Inspect the probe cable and connector periodically for signs of wear or damage. 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 PPS tip and stainless steel case resist corrosion in humid or harsh environments.
Compatibility & Integration
This 5-meter probe is designed exclusively for use with the 5-meter Proximitor sensor. For intrinsic safety applications, refer to drawing 141092 for zener barriers or use galvanic isolators. For non-incendive installations, follow drawing 140979. The miniature coaxial ClickLoc connector ensures a secure, quick connection.
