Product Overview
When replacing a worn proximity probe in a critical rotating machine, the Bently Nevada 330173-00-03-10-02-00 offers a direct and dependable solution. This 3300 5mm Probe uses an M8 x 1 thread and does not include armor, making it suitable for standard mounting configurations. The part number encodes a unique set of options: unthreaded length 0 mm, overall case length 30 mm, total length 1.0 metre, miniature coaxial ClickLoc connector, and no agency approval. The use of a polyphenylene sulfide (PPS) tip and AISI 304 stainless steel case ensures long service life in demanding environments.

Real-World Use Cases
The Bently Nevada 330173-00-03-10-02-00 is designed for monitoring radial or axial shaft vibration in steam turbines, gas turbines, compressors, and large pumps. When a machine's rotor dynamics change, this probe provides the precise displacement signal needed for predictive maintenance systems. Because the model number 330173-00-03-10-02-00 matches the 3300 series form factor, you can use it to upgrade existing installations without re-engineering the mounting geometry.
Installation & Setup Guidance
Mount the probe in a clean, threaded hole using the M8 x 1 thread. Apply the recommended torque of 5.1 N·m, and never exceed the 7.3 N·m maximum. Thread engagement must not extend beyond 12 mm, or the probe tip can contact the target prematurely. Route the 75 Ω triaxial cable with a bend radius of at least 25.4 mm to protect the conductor and dielectric. For the connector-to-connector joint, tighten to a maximum of 0.565 N·m.
Maintenance & Reliability
Regular inspection of the probe tip and cable is essential for continued accuracy. The PPS tip withstands many process fluids, but any contamination or scoring affects the eddy-current measurement. Keep the probe within the -35°C to +177°C range; exposing it to temperatures below -34°C may damage the internal pressure seal. Verify the probe's DC resistance periodically to catch early cable failures.
Selection Guide & Buying Advice
Before purchasing, confirm the overall case length (30 mm) and total cable length (1.0 metre) fit your installation. If your system requires a different option, check the complete Bently Nevada 3300 series range.
