Product Overview
The Bently Nevada 330174-00-02-20-12-05 is a 3300 series 5 mm proximity probe with an M8 x 1 thread and integral armor. This industrial automation module provides dependable eddy-current proximity sensing for displacement, vibration, and position monitoring applications. The 330174-00-02-20-12-05 comes from a U.S. manufacturing line and includes a 2.0 m total length, a 20 mm overall case, and a FluidLoc cable with miniature coaxial ClickLoc connector.
Technical Specifications
Each measurement parameter below traces directly to the verified configuration data for the Bently Nevada 330174-00-02-20-12-05. The probe tip uses polyphenylene sulfide (PPS), while the probe case uses AISI 304 stainless steel. The armored design protects the cable in harsh industrial environments.

Field Applications
Use the 330174-00-02-20-12-05 in rotating machinery applications that require accurate shaft vibration monitoring and axial position measurement. The 5 mm sensing element fits compact bearing housings, while the 2.0 m armored cable keeps the connection point near the machine casing. Process plants and utility systems often install this probe as a replacement for aging 3300 series sensors.
Installation and Replacement Guidance
Before installing the Bently Nevada 330174-00-02-20-12-05, verify that the mounting thread is M8 x 1 and the target material matches the system requirements. Apply a probe case torque of 5.1 N·m for most installations, and never exceed 7.3 N·m. Keep the cable bend radius above 25.4 mm to avoid internal damage. Set the initial gap near 1.27 mm because the system is characterized at that spacing. When replacing an older probe, confirm the total length matches the previous configuration; this model provides 2.0 m of cable with a miniature coaxial ClickLoc connector and FluidLoc cable for secure field connection.
Maintenance and Reliability
Inspect the armored cable regularly for cuts, kinks, or crushed areas. Use the connector-to-connector torque of 0.565 N·m maximum when tightening the ClickLoc connection. Keep the probe tip clean; PPS material resists many process contaminants but still benefits from routine inspection. The probe temperature range covers -35°C to +177°C, and sustained exposure below -34°C may cause premature failure of the pressure seal.
Selection Guide
When ordering a replacement proximity probe, verify the exact part number Bently Nevada 330174-00-02-20-12-05 to ensure the unthreaded length, overall case length, cable length, connector, and approvals match your original configuration. This unit uses a 0 mm unthreaded section, a 20 mm overall case, and a 2.0 m FluidLoc cable with a miniature coaxial ClickLoc connector. If your application requires a different cable length, review the 3300 series cable options before purchasing.
