330103-15-23-05-02-CN Long Tip Probe Bently Nevada

Extra Long-Reach 8mm Probe for Deep Machine Casings

The Bently Nevada 330103-15-23-05-02-CN belongs to the trusted 3300 XL series. We design this extra long-reach 8mm probe for accurate displacement and vibration measurements through deep bearing housings and thick machine casings. The 150mm unthreaded tip reaches past obstacles before threads engage. It operates within a 2mm (80 mils) linear range, starting at 0.25 mm from the target. For radial vibration monitoring, we recommend a gap setting of -9 Vdc, which equals approximately 1.27 mm.

Environmental and Operating Ranges

• Temperature (Standard): Operates and stores from -52°C to +177°C (-62°F to +350°F).
• Temperature (Extended): Probe tip reaches -52°C to +218°C (-62°F to +425°F). Cable and connector handle up to +260°C.
• Humidity: Average Scale Factor changes less than 3% after 56 days in 93% humidity.
• Pressure Seal: Uses Viton® O-ring to seal differential pressure between tip and case.
• Deep Reach Design: The 150mm smooth section passes through deep housings to reach internal shaft targets.

Installation and Mounting Guide

• Thread Engagement: Maximum thread engagement length is 15 mm for M10x1 case thread.
• Torque (Forward Mount): Recommended torque is 11.2 N•m (100 in•lbf). Maximum rated torque is 33.9 N•m.
• Torque (First Three Threads): Use recommended torque of 7.5 N•m (66 in•lbf). Do not exceed 22.6 N•m.
