Product Overview
When a legacy 3300-series proximity probe starts delivering erratic displacement readings, upgrading to the Bently Nevada 330173-00-18-10-02-05 restores accurate vibration monitoring. This 3300 5mm Probe uses an M8 x 1 thread and arrives without armor, making it suitable for internal machine train measurements. The miniature coaxial ClickLoc connector with standard cable simplifies the replacement process, so you can swap out older transducers without redesigning your monitoring loop.
This probe features a polyphenylene sulfide (PPS) tip and a case machined from AISI 303 or 304 stainless steel. The 1.0 metre (3.3 feet) total length, 180 mm overall case length, and 00 mm unthreaded length match common 3300 system layouts. Because the Bently Nevada 330173-00-18-10-02-05 is made in the U.S.A., you get consistent manufacturing quality for critical machinery protection.

Installation Guidance
Install the Bently Nevada 330173-00-18-10-02-05 with care to avoid thread damage. Engage the M8 x 1 thread to a maximum of 12 mm. Apply a probe case torque of 5.1 N·m (45 in·lb) recommended, and never exceed 7.3 N·m (65 in·lb). For connector-to-connector joints, use a maximum torque of 0.565 N·m (0.42 ft·lbf). Keep the cable bend radius above 25.4 mm (1.0 in) to prevent internal wire fatigue. These torque limits protect both the probe and the surrounding equipment.
Maintenance & Reliability
Maintaining the 330173-00-18-10-02-05 is straightforward when you monitor its operating environment. Do not expose the probe to temperatures below -34°C (-30°F); the pressure seal may fail prematurely. The upper limit is +177°C (+351°F), so verify the bearing housing or casing temperature stays within this range. Periodically inspect the gold-plated connectors, which are made from gold-plated brass or gold-plated beryllium copper, for corrosion or looseness. Replacing worn probes before failure reduces unplanned downtime and protects downstream machinery.
Selection Guide & Purchasing Advice
Before purchasing, confirm that the Bently Nevada 330173-00-18-10-02-05 matches your system requirements. Verify the unthreaded length (00 mm), overall case length (180 mm), and total length (1.0 m). Make sure your extension cable uses the miniature coaxial ClickLoc connector. The agency approval option 05 indicates multiple approvals, so check that these align with your site certification needs.
