Installation & Setup Guidance
When mounting the 330171-00-08-50-02-CN probe, drill and tap a hole for the 1/4-28 UNF thread using a #3 or larger tap drill. The maximum thread engagement length is 0.375 in. Tighten the probe case to the recommended torque of 5.1 N·m (45 in·lb), not exceeding 7.3 N·m. Ensure the cable bend radius stays above 25.4 mm to avoid damage. The miniature coaxial ClickLoc connector provides a secure connection.
Maintenance & Reliability
The Bently Nevada 330171-00-08-50-02-CN probe is built for longevity with a stainless steel case and PPS tip. Avoid exposing the probe to temperatures below -34°C (-30°F) to prevent premature seal failure. In high magnetic field environments (up to 300 Gauss at 60 Hz), typical output voltage variations remain low—for example, at 50 mil gap the probe contributes only 0.0014 mil pp/gauss. Regular inspection of the cable and connector integrity is recommended to maintain measurement accuracy.
Selection Guide & Purchasing Advice
Before purchasing, verify the probe length (5.0 m), connector type (miniature coaxial ClickLoc), and agency approval (CN for country-specific approvals). For genuine Bently Nevada 330171-00-08-50-02-CN probes, rely on PLC Source PRO for authentic parts and expert support.
