Installation & Setup Guidance
When installing the 330171-00-12-10-02-CN probe, ensure proper thread preparation. For the 1/4-28 UNF thread, use a #3 or larger tap drill when drilling and tapping the mounting hole. Apply the recommended probe case torque of 5.1 N·m (45 in·lb) to avoid damaging the case or threads; do not exceed 7.3 N·m (65 in·lb). The connector-to-connector torque should be limited to a maximum of 0.565 N·m (0.42 ft·lbf). Adhere to the minimum cable bend radius of 25.4 mm to prevent internal conductor damage. Avoid exposing the probe to temperatures below –34°C (–30°F) as this may compromise the pressure seal.
Maintenance & Reliability
Regular inspection of the Bently Nevada 330171-00-12-10-02-CN probe cable and connector is essential for reliable operation. Check for signs of wear, corrosion, or mechanical stress at the connector interface. Periodically verify that the mounting thread remains clean and that the probe case torque is within specification. The robust PPS tip and AISI 304 case offer excellent chemical resistance and durability in harsh industrial settings. Following these practices extends service life and reduces unplanned downtime.
Selection Guide & Purchasing Advice
Before purchasing the Bently Nevada 330171-00-12-10-02-CN, confirm that the overall cable length (1.0 metre) and connector type (miniature coaxial ClickLoc) match your system requirements. This probe is designed for use with Bently Nevada 3300 series proximity transducer systems. Ensure your power supply provides the required -17.5 Vdc to -26 Vdc range.
