Industry Applications
Replace or upgrade legacy proximity probes in turbines, compressors, pumps, and other rotating equipment with the Bently Nevada 330171-00-20-10-02-05. Its robust construction and multiple agency approvals make it suitable for harsh environments. The PPS tip and stainless steel case resist wear and corrosion, extending service life.
Installation & Setup Guidance
For proper mounting, drill and tap a hole for 1/4-28 threads using a #3 or larger tap drill. Apply recommended torque of 5.1 N·m (45 in·lb) to the probe case (maximum 7.3 N·m). Maintain minimum cable bend radius of 25.4 mm (1.0 in). Avoid exposing the probe to temperatures below –34°C to prevent pressure seal failure. The miniature coaxial ClickLoc connector ensures secure cable attachment.
Selection Guide & Purchasing Advice
Before ordering, verify that the Bently Nevada 330171-00-20-10-02-05 matches your system requirements. The unthreaded length option is 0 inches, overall case length 2.0 inches, and total cable length 1.0 meter. Check connector compatibility with your proximitor or extension cable.
