For a 3300 5 mm system (with Proximitor and extension cable) the linear range is 1.52 mm (60 mils) from 0.25 to 1.78 mm, and the incremental scale factor is 7.87 V/mm (200 mV/mil) ±6.5% over the full linear range.
Industry Applications
This proximity probe excels in turbomachinery, pumps, compressors, and electric motors where shaft vibration and axial position must be monitored continuously.
-
Turbo compressors: The 146054-08-90-00-05 detects early bearing wear and rotor instability, preventing catastrophic failures.
-
Hydroelectric generators: Its ceramic tip resists harsh environments and delivers stable readings for thrust bearing monitoring.
-
Paper mill rollers: With a 9-meter cable, this Bently Nevada 146054-08-90-00-05 simplifies routing to remote Proximitor sensors, reducing installation cost.
Installation & Setup Guidance
Mount the probe with the 3/8-24 UNF thread into a properly tapped hole. Ensure the target surface is clean and free of runout. Use the provided 0.563-inch maximum thread engagement to avoid bottoming out. Connect the 75 Ω coaxial cable to a compatible Proximitor (not included). Calibrate the system against an AISI 4140 steel target for accurate readings.
Maintenance & Reliability
Inspect the probe cable for cuts or abrasion regularly. Verify the tip is clean and free of metal debris. The ceramic tip resists wear, but check for cracks during routine shutdowns. Operating within -51°C to +177°C ensures stable performance. Because this Bently Nevada 146054-08-90-00-05 is new and factory-sealed, you get maximum service life.
Selection Guide & Purchasing Advice
Before ordering, confirm your system’s required probe length and connector type. This model uses a 9.0-meter cable and no connector; ensure your Proximitor accepts this configuration. For hazardous areas, the CSA, ATEX, and IECEx approvals cover most installations.
