Product Overview
The Bently Nevada 330173-08-18-10-02-00 is a genuine 3300 series 5mm proximity probe engineered for precision vibration monitoring in critical rotating machinery. This model replaces or upgrades older 3300-series probes with an M8 x 1 threaded case, an 80 mm unthreaded length, and a 180 mm overall case length. With a total length of 1.0 meter, the probe integrates seamlessly into existing Bently Nevada monitoring systems, ensuring minimal downtime during retrofit projects.

Installation and Setup
Mount the probe using the M8 x 1 thread and engage a maximum thread length of 12 mm. Apply a recommended torque of 5.1 N·m and never exceed the maximum torque of 7.3 N·m to avoid damaging the case or threads. Maintain a minimum cable bend radius of 25.4 mm to protect the internal cable and preserve signal integrity.
Maintenance and Reliability
Inspect the probe and cable regularly for signs of wear or mechanical damage. Keep the probe tip clean and ensure it remains within the specified temperature range of -35°C to +177°C; prolonged exposure below -34°C may cause premature failure of the pressure seal. The 330173-08-18-10-02-00 uses a polyphenylene sulfide tip and AISI 304 stainless steel case for long-term durability in harsh environments.
Troubleshooting and Common Issues
If you experience signal noise, verify that the probe and extension cable connectors are properly seated and free of contamination. Over-torquing the mounting threads can deform the case; always use a torque wrench. The probe exhibits minimal sensitivity to 60 Hz magnetic fields up to 300 Gauss, but avoid routing cables near high-current conductors for stable output.
Selection Guide
Before ordering, confirm the unthreaded length (08 = 80 mm), overall case length (18 = 180 mm), total length (10 = 1.0 m), and connector option (02 = miniature coaxial ClickLoc). When replacing an existing probe, match these options to your system requirements.
