Product Overview
For decades, machinery protection relied on contact sensors that wore out and drifted. The shift to non-contact eddy current measurement changed everything. The Bently Nevada 146054-08-10-01-05 continues that evolution. This 3300 ceramic capped proximity probe delivers reliable displacement data for critical rotating equipment.
What Is the 146054-08-10-01-05?
It is a 3300 Series probe with a ceramic cap, a 3/8-24 UNF thread, and no armor. The 1.0 meter total length suits tight installations. A miniature coaxial ClickLoc connector with protector ensures a secure, stable connection. The probe meets CSA, ATEX, and IECEx approvals for hazardous areas.

Key Performance Insights
The linear range spans 1.52 mm (60 mils), from 0.25 to 1.78 mm (10 to 70 mils). This range provides ample measurement window for radial vibration and axial position. The incremental scale factor is 7.87 V/mm (200 mV/mil) ±6.5% over the linear range from 0°C to +45°C. That consistency means you can trust the data for protection and diagnostics.
The ceramic tip resists wear and harsh chemicals. The AISI 304 stainless steel case handles corrosive environments. With a pressure rating of 34 Bar (500 psi), the probe seals reliably in high-pressure applications.
Applications in Oil, Gas, and Industrial Automation
In a refinery, this probe monitors compressor shaft vibration. Its ATEX and IECEx approvals allow installation in Zone 0, 1, or 2 hazardous areas. The ceramic cap withstands process gas contaminants. In a power plant, the probe tracks turbine axial displacement. The 1.0 meter length fits tight bearing housings. For pipeline pumps, the probe provides early warning of bearing wear, preventing unplanned downtime.
Installation and Setup
Mount the probe using the 3/8-24 UNF thread. Ensure the target is AISI 4140 steel for specified accuracy. Maintain the linear range between 0.25 and 1.78 mm from the target. Use the ClickLoc connector to attach the extension cable. Verify the -24 Vdc power supply and 10 kΩ load. Follow the manufacturer’s safety manual for hazardous area installations.
Maintenance and Reliability
Inspect the probe tip periodically for ceramic damage. Check cable insulation for cracks or abrasion. Keep the connector clean and dry. The 3300 series is known for long service life, but environmental factors like extreme temperature cycling can affect performance. Replace the probe if the incremental scale factor drifts beyond ±6.5%. For fast dispatch, worldwide, contact Oil AutoTech.
